Marketplace Buyer Asking for Your Phone Number? Read This

Why a Facebook Marketplace Buyer Is Asking for Your Phone Number

Plenty of buyers ask for a number for dull, legitimate reasons. They'd rather text than keep an app open. They're bringing a truck and a friend and want an easy way to say they're ten minutes out. They rarely use Messenger, or they've missed messages there before. If you've ever asked a seller for a number yourself, it was probably for one of these reasons.

The scam version of the same request looks different, and timing is the giveaway. Meta's Marketplace scam guide lists buyers or sellers who ask you to contact them outside Facebook or Messenger, by phone, text, or email, among its warning signs, and it stresses early requests in particular. It also gives the reason: once a conversation moves off Facebook, Messenger, and WhatsApp, scams become harder to detect and track.

An honest buyer's reasons for wanting a number are all about logistics, and logistics don't exist until you've agreed on a price, a time, and a place. A request that shows up in the second or third message, before a single question about the item, has nothing to coordinate yet. That's the moment to ask yourself what the number is really for.

Listen to the reason the buyer gives, too. "Can I text you when I'm on my way?" is about logistics. "Messenger keeps glitching," "my account is restricted," and "I verify every seller" are stories, and their only job is to move you somewhere else.

When the request is a setup, it's usually laying the groundwork for one of four things:

• A code request. Your number is the raw material for the verification code scam, because the buyer needs a code sent to your phone.
• A private channel. Once you're texting, the rest of the conversation happens where Meta can't see it, which is exactly why Meta flags the move.
• A route for fake notices. A text that looks like a payment confirmation or a warning from "Marketplace support" lands next to your real messages, where it's easier to believe.
• A contact that outlives the sale. Your listing disappears when the item sells. Your number stays in the buyer's phone, where it can be reused or passed along.

So the useful question isn't whether this buyer wants your number. It's what they need it for right now that the app can't already do. Early in a chat, the honest answer is almost always nothing.

What a Scam Buyer Can Do With Your Number

It helps to see what a phone number is worth to someone running Marketplace scams, because that explains why they work so hard to get it. The payoff tends to come in stages.

In the first few minutes: a code you didn't ask for

The quickest return is a verification code, requested under some pretext as soon as the buyer has your number. It's common enough to get its own section below. The short version is that the code unlocks something for the person asking, never anything that helps you sell your item.

Over the next few days: texts that seem to come from someone else

With your number and the knowledge that you're selling something, a scammer can write texts that fit your situation exactly. A payment service says the buyer's money is "pending" until you confirm your details. A "Marketplace team" notice says your listing was reported and will come down unless you verify your account. A courier needs a small fee before it can collect the item.

Meta describes smishing as the use of SMS messages to trick people into visiting phony sites from their phones, and lists it among the phishing scams seen on Marketplace. Each of these texts follows that pattern: the link leads to a page built to collect a login, a card number, or another code.

Example phishing text after a seller shared their number

+1 (414) 555-0119

Text Message

MKTPLACE PAY: A buyer has sent $240.00 for your listing "Oak dining table". Funds are on hold until you verify your seller account: mkt-pay-release.example/verify

Unverified payments are returned to the buyer after 30 minutes.

Notice what that text knows: that you're selling, what you're selling, and roughly what it's worth. Anyone who chatted with you about the listing has all three, which is why a text like this can feel personal and legitimate. The countdown is there to keep you from checking your actual payment app first.

Months later: the long tail

Most of what follows a shared number is noise rather than danger: wrong-number openers, fake job offers, and prize texts that show up long after the table has gone. Some of it is harder to shrug off. A number can be run through people-search sites that may connect it to a name and past addresses, and it's the thing many of your accounts use to confirm it's really you.

Our guide to what someone can do with your phone number ranks these risks from nuisance to serious. It's a useful corrective in both directions, because it also covers what someone generally can't do with a number alone, such as hacking your phone just by knowing it.

None of this is inevitable. Many sellers share a number with a buyer and never hear another word. But nearly every cost of giving it to the wrong person lands on you, and a phone number is far easier to hold onto than to take back. That imbalance is the whole argument for waiting until a pickup is actually arranged.

The Marketplace Code Scam: Why a Verification Request Gives It Away

If a buyer asks for your number and then mentions a code, you've found the most common reason behind the request. The story changes from buyer to buyer. They "verify every seller" after being scammed once. They want to "make sure you're not a bot." They claim Facebook requires sellers to confirm their identity before a sale. Then a text arrives, often from Google Voice, and they ask you to send them what it says.

With a Google Voice code, reading it back lets the scammer attach your phone number to a Google Voice account they control, typically so the number they use on their next target is tied to your phone instead of theirs. Our guide to the verification code scam on Facebook Marketplace walks through the mechanics and the other codes buyers ask for, such as Facebook login codes and WhatsApp registration codes.

You don't need the mechanics to spot it, though. The four sources below all give the same answer, and it's unusually absolute:

• Meta includes verification codes sent to your phone or email among the things phishing scammers on Marketplace try to get, and gives a Google Voice code as an example (Meta's Marketplace scam guide).
• Google tells people in its Google Voice Help center not to share a verification code with anyone, and says Google employees will never ask for it.
• Craigslist says in its help pages on avoiding scams that requests for a "code" or "verification" are always a scam.
• The FTC, in its guide to two-factor authentication, says not to share a verification code with anyone you didn't contact first, "no matter what the story is," and warns that scammers try to trick people into handing these codes over.

That FTC phrasing is the most useful of the four, because the story is where these scams put their effort. A buyer who seems anxious about being cheated, who's polite and apologetic, who offers to pay extra for the trouble, is still asking for the one thing no buyer ever needs. A polished story is a sign of practice, not of honesty.

Honest Buyer or Setup? What to Check Before You Share

No single message proves a buyer is a scammer, and plenty of real people write short, blunt, or clumsy messages. What gives a setup away is the pattern: when the number comes up, what the buyer says it's for, and what they ask for next. The table sets the two side by side.

What to look at	Usually an honest buyer	Usually a setup
When they ask	After agreeing on a price and a pickup window	In the first few messages, before discussing the item
What they've asked about the item	Condition, measurements, whether it fits in a hatchback	Nothing, or "is this available?" followed by the number request
The reason they give	"So I can text you when I'm outside"	"Messenger is glitching," "my account is restricted," "I verify all sellers"
If you'd rather stay in the app	They keep chatting there	They insist, change the story, or go quiet
Price	Negotiates, or accepts the listed price	Offers more than you asked, or never mentions price
Who you'll deal with	The person messaging you	A relative, an assistant, a courier, or movers
What follows the number	A time and a place	A code, a link, a request for your email, or a payment "confirmation"

Some rows carry more weight than others. A buyer who asks for your number a little early but otherwise talks about the item, the price, and a time is probably just impatient. A buyer who wants to hand you off to someone else is showing a pattern Meta flags directly: requests to deal with people, such as relatives, who aren't the owner of the Facebook account. Anything in the last row, whether it's a code, a link, or a sudden interest in your email address, settles the question.

Pressure deserves its own mention. Meta's list of warning signs includes people who push you to move quickly to complete a sale. Honest buyers can be eager, but a scammer needs you to act before you think, and a number request wrapped in urgency ("I can come right now if you just text me") is doing two jobs at once.

The quickest test is to offer an alternative and watch what happens. Suggest staying in Messenger until pickup. Most honest buyers shrug and carry on. A scam buyer tends to push harder, invent a new reason, or vanish, because the plan depended on getting you off the platform. Either response tells you something useful, and you haven't given anything away to learn it.

Profiles are worth a glance, but they're weak evidence in both directions. Real people who rarely post often have thin profiles, and an established-looking account can be a stolen one. Let the request decide, not the profile photo.

What to Say When a Buyer Wants Your Number

You don't need to accuse anyone or explain your reasoning. A short, friendly boundary, stated once and repeated if needed, works on honest buyers and wastes a scammer's time. These replies cover the situations that come up most often. Adjust the wording to sound like you.

When they ask in the first few messages

"I keep everything in Messenger until we've set a pickup time. Is there anything you'd like to know about the table?"

The question at the end does the real work. It steers the conversation back to the item, which is where an honest buyer wants to be anyway, and it gives a scammer nothing new to use.

When they say they don't really use Messenger

"No problem, it's only a couple more messages. When would you like to come see it?"

They found your listing and messaged you on Facebook, so the app evidently works well enough for a few more lines. If Messenger truly is a struggle for them, they'll still manage a time and a place, and you can decide about a number after that.

When they want to verify you with a code

"Codes that come to my phone stay on my phone. You're welcome to see it in person before you pay."

After that, don't negotiate. If the reply is that it "only takes a second" or that they can't buy without it, you have your answer. Stop replying and report the conversation to Facebook, which is what Meta's guidance says to do when you suspect a scam.

When they ask for your email instead

An email address is the same request by another road. Meta warns about fake emails that appear to come from payment apps such as Zelle or Venmo and ask you to take some kind of action, and a scammer can only send you one if they have your address.

"I'd rather keep it here. Payment is cash at pickup, so there's nothing we need to email."

When they push

"That's my rule for every sale. If it doesn't work for you, no hard feelings."

Then stop typing. Every extra explanation gives a scammer something to argue with, and you don't owe one. Losing a sale to a buyer who wouldn't send two more messages in the app is a fine outcome.

When the pickup is set and they want a way to reach you

This is the honest version of the request, and it deserves a yes of some kind. You can share your number, share a second number, or send the first text yourself from a masked number so the buyer has a way to reach you without seeing your real one:

"See you Saturday at 10 at the library parking lot. I'll text you that morning so you have a way to reach me."

A buyer who has agreed to a time and place and wants a way to say "stuck in traffic" is exactly who a pickup-day text is for.

When It's Fine to Give a Buyer Your Phone Number

This guide isn't an argument for never sharing your number. For many sales, a number shared at the right moment is a reasonable trade, and refusing on principle can make a simple pickup harder than it needs to be. An honest buyer holding your number is a small risk. The real risk is handing it to someone who only looks honest, which is why the moment you share matters more than the decision itself.

Sharing is usually reasonable when all of these are true:

• You've agreed on the item, the price, and a time and place, and that agreement is written down in the app.
• The buyer has asked real questions about the item.
• Nobody has mentioned a code, a link, shipping, a courier, or a relative who'll handle things.
• You're meeting somewhere public, or the buyer is collecting from you, and payment is cash or an app payment you'll confirm yourself.
• You'd shrug if the number ended up on a spam list.

Some situations lean the other way even when the buyer seems genuine:

• Your number guards important accounts. If your email or bank sends login codes to this number, every stranger who holds it is someone who could try the code trick on you later.
• You'd rather not be easy to look up. If you've dealt with harassment before, or you simply value that separation, remember that a number can lead to a name and an address.
• You sell often. Ten buyers a month means ten more people holding your number, and the exposure adds up. Selling regularly with your real number is one of the signs you should stop sharing your phone number.
• The item is expensive. Craigslist's safety tips single out high-value items as a reason to be especially careful, and a costly sale is where a scammer's effort is best rewarded.

Whatever you decide about individual buyers, keep your number out of the listing itself. A number in a listing's description is visible to everyone who scrolls past, not only the buyers you've vetted, and it invites a kind of contact Meta flags on its own: people reaching you about a Marketplace listing from outside Marketplace. Posting a number publicly heads the list in our guide to phone number privacy mistakes. It's also worth checking whether your number is visible in your Facebook profile's contact details, since a buyer who can see it there doesn't need to ask. Menu names shift between app versions, so look for your profile's contact info and its audience setting.

The same idea, that a number is earned by someone showing real intent, holds well beyond selling. Our guide on giving your number to someone from a dating app turns it into a three-question test for a situation where the stakes are more personal.

How to Text a Buyer Without Sharing Your Real Number

If the only reason you'd share your number is pickup-day logistics, you have options that handle the logistics without the exposure. They differ in cost, effort, and what the buyer ends up holding.

Option	What the buyer sees	Best for	Trade-offs
The app's own chat	Your profile, not your number	Most sales, start to finish	A buyer who's driving may not have the app open
A masked text	A protected sender ID	Pickup-day messages without a second line	Text only, with a small cost per message
A second-number app	A separate number you keep	Frequent sellers who want buyers to be able to ring them	Another number to manage, usually set up with your real number
A second phone or prepaid SIM	A separate number on separate hardware	Heavy resellers and small businesses	Ongoing cost and a second device
Your real number	Your personal number, for good	Buyers you already know	Can't be taken back

The app's own chat is the default for good reason. It's free, it keeps the whole conversation in one place, and if something goes wrong, you can report the buyer from the same thread. Its weak spot is pickup day, when a buyer circling a parking lot may not have the app open.

A masked text covers that gap. Ghost sends your message with your real number hidden, so the buyer sees a protected sender ID instead (how the masking works). If they need to answer, a Reply Link lets them respond without your number ever appearing on their screen. As of September 2026 it's pay-as-you-go at about 20¢ per text, credits never expire, and there's no subscription (pricing). It only sends texts, so a buyer who wants to talk on the phone would need one of the other options. And masking hides your number from the buyer, not from Ghost, your carrier, or lawful legal process.

Text Message

Hi Marcus, it's Dana from Marketplace. Still good for 10 at the library lot? I'm in a green hatchback near the book drop.

Yes! Running about 5 minutes behind, gray pickup.

No rush. Table's ready, cash is fine.

A second number makes sense if you sell often and want buyers to be able to ring you. Services such as Google Voice give you a separate number, but Google's help center describes a setup that confirms your phone by texting it a code, so your real number still sits behind the account. That same confirmation step is the one the code scam hijacks. For a side-by-side look at the two approaches, including cost and how replies work, see number masking vs a second phone number.

A second phone or prepaid SIM gives the cleanest separation and costs the most in money and hassle. It's overkill for selling one bookshelf, but it's a common setup for people who resell regularly or run a small business on the side.

Your real number is still a fine choice for buyers you already know, like a coworker buying your old monitor or a neighbor you've met. The point isn't secrecy for its own sake. It's that strangers get your number only once they've given you a reason to trust them.

OfferUp and Craigslist Buyers Asking for Your Number

The request isn't unique to Facebook. An OfferUp buyer asking for your phone number, or a Craigslist reply that wants to "just text instead," is usually after the same things, and the same timing test applies. What changes is the tool you use to keep the conversation where it belongs.

On OfferUp

OfferUp has its own in-app messaging, and it plays the role Messenger plays on Facebook: a written record of what you agreed, kept in the app where you and the buyer found each other. Treat an early request to move to text the same way, and use the same replies. A buyer who asks for your number and then mentions a code is running the same scam no matter which app they found you on.

The phishing follow-ups adapt to the platform, too. A seller on OfferUp may see fake notices that borrow OfferUp's name rather than Facebook's, with the same structure: a payment on hold, an account to verify, a link to tap. The defense doesn't change. Check your payment app or the marketplace app by opening it yourself, never through a link in a text.

On Craigslist

Craigslist works differently, because many replies to a listing arrive by email through Craigslist's mail relay. Craigslist's help pages describe a good interaction as one that uses that relay to discuss a specific item, and they list requests to call or email for more information among the things to be wary of.

So a reply to your Craigslist post that skips the item and asks for your number fits a pattern Craigslist describes itself. Answer through the relay, keep the conversation about the item, and decide about contact details only once a meetup is arranged. If you listed a phone number in the post, expect texts from people who never used the relay at all, and treat any that ask for a code the way you'd treat them anywhere else.

Everywhere else

Most other selling apps and neighborhood buy-and-sell groups have some kind of built-in messaging. Whatever the platform, that chat is your Messenger: use it until the meetup is set, then decide whether a number is worth sharing. The warning signs in the table above don't depend on the app, because the scams don't either.

Already Gave a Buyer Your Number? What to Do Next

If you've already shared your number, don't panic. Most of the time nothing comes of it. What matters is recognizing the few follow-ups that do mean trouble, and knowing what to do about each.

If nothing unusual has happened

Finish the sale as planned, and keep the important details, such as the price, the time, and the payment method, confirmed in the app rather than only by text. Afterward, block the buyer's number if you don't expect to hear from them again. For the next few weeks, be skeptical of any text that mentions your listing, a payment, or a delivery, and don't tap links in them. Open the app or website you'd normally use instead.

If a code arrives that you didn't request

Don't share it, in any format. A code you didn't ask for means someone typed your number into a sign-up or login screen. If it's for an account you own and you weren't trying to sign in, open that service's app directly, change the password, and review its security settings. If it's a Google Voice code and you don't use Google Voice, keeping it to yourself is enough to stop that attempt.

If you already read a code to the buyer

Act on it the same day. What to do depends on which code it was:

• A Google Voice code. The Google Voice Help center covers this in its article on protecting your verification code, which speaks directly to people who aren't Google Voice users but were scammed into giving one up, and explains how to disconnect your number from Google Voice. If you do use Google Voice and another account has claimed your linked number, Google's article on reclaiming a Voice number walks through adding it back as a linked number and verifying it.
• A login code for one of your own accounts, such as Facebook, WhatsApp, email, or your bank. Go to that service's official app or website, change the password, sign out of sessions you don't recognize, and contact the company if you're locked out. For a bank, use the number on your card.
• Any code at all. Stop replying to the buyer, save screenshots of the conversation, and report it to the platform. Our guide to what to do if you were scammed as a seller has the full recovery checklist, including where to file official reports.

If scam texts start arriving

Don't reply, not even with STOP or "wrong number." A reply confirms that your number reaches a real person who reads their messages. Our guide on what happens if you reply to a scam text explains when STOP is safe to send and how to report and block scam texts on iPhone and Android.

If the buyer won't stop contacting you

Block the number and the buyer's Facebook profile, and don't engage. If the messages turn threatening, or the person turns up where you are, save everything, note dates and times, and contact your local police. Harassment laws vary by state and country, and this is general information rather than legal advice; the police or a lawyer can tell you what applies where you live.

Make your number less useful to a scammer

The longer-term risk of a shared number usually isn't the buyer. It's that your number is how many of your accounts decide it's really you. The FTC's guide to two-factor authentication calls text-message codes common and simple, but notes they can be intercepted through a SIM swap, where someone takes over your phone number. It describes authenticator apps as a safer choice because a SIM swap can't touch them, and security keys as the strongest form of two-factor authentication.

Moving your email, your bank, and your main social accounts to an authenticator app where they offer one means a stranger who holds your number has far less to work with. It's also worth asking your carrier whether it offers an account PIN or other protection against unauthorized SIM changes and number transfers. Carriers name and offer these differently, so ask what's available on your plan. Our explainer on SIM swaps and account takeover covers the warning signs to watch for.
