How to Sell on Facebook Marketplace Anonymously

Short answer: Not completely. Outside the EU, you need a Facebook account to sell on Marketplace, and buyers can see your Marketplace profile. What you can do is keep everything else private: keep chats on Facebook, lock down your profile, never give out your real number, and meet in a public place. If a buyer wants to call or text, give them a second number instead of your own.

Can You Sell on Facebook Marketplace Anonymously?

Not fully. Marketplace is part of Facebook, so you sell from your Facebook account, and buyers can see your Marketplace profile and ratings.

There's one exception. In the EU, EEA and Switzerland, Facebook lets people use Marketplace without their Facebook information, with chats handled by email. Elsewhere, that option doesn't exist.

So the realistic goal isn't to be invisible. It's to stop a stranger from getting from your listing to your phone number, your home and the rest of your life.

What Can Go Wrong When You Share Your Number

• Buyers who won't stop. You tell them it's sold, and they keep texting or calling at odd hours.
• Scams. Fake payment confirmations, phishing links and "verification code" tricks are common. A scammer who has your real number can keep pushing.
• Lookups. Your number can lead to your name and address through a people-search site. See can someone find your address from your phone number.
• Harassment after a bad sale. An unhappy buyer with your real number doesn't need the platform to reach you.

How to Keep Your Privacy on Marketplace

1. Keep chats on Facebook as long as you can

Meta's own advice is to keep conversations on Facebook and not share personal details you don't need to. Messenger is enough for most sales.

2. Lock down your Facebook profile

Buyers can tap through to you. Before you list:

• Set past posts, your friends list and photos to Friends or Only Me.
• Remove your workplace, hometown and any photo that shows your house or street.
• Check what a stranger sees using Facebook's "View as" option on your profile.

3. Give buyers a second number, never your real one

Some buyers want to text for a quick pickup. When that happens, give them a second number. A second number is a real number they can call and text, but it isn't your personal one, so a lookup won't lead to you and you can block or stop using it without changing your own number.

TINE gives you a real US, UK or Canadian number for calls and texts in your browser, from $5 a month. Pick an area code where you sell, and use it for every listing.

4. Don't share your address until you need to

Meet in a public place when you can. Many police stations have marked areas for marketplace exchanges. For large items that have to be collected from home, share the address only when the buyer is confirmed and on their way, and have someone with you.

5. Never share a verification code

If a buyer asks you to read out a code sent to your phone "to prove you're real", stop. It's a common scam to take over your number or your accounts.

6. Take safe payments

Cash in person is simplest. Be wary of checks, overpayments and anyone who wants to pay before they've seen the item.

Platform-by-Platform Tips

Facebook Marketplace

Buyers see your Marketplace profile, so the profile clean-up above matters most. Keep chats in Messenger, and switch to a second number only if you need to text.

Craigslist

Craigslist hides your email behind a relay address for free postings. It doesn't mask phone numbers: if you tick "show my phone number", the number in your post is shown as typed. That makes a second number the best choice for the number you show buyers.

One catch: some postings need phone verification, and Craigslist says VoIP numbers aren't supported for that step. Verification numbers aren't shown on your posts, so you can verify with your own mobile and still show buyers your second number.

OfferUp

OfferUp has in-app chat, so you rarely need to share a number. Its optional phone check only supports US mobile numbers, not VoIP. If a buyer wants to text, give them your second number; just don't expect it to work for OfferUp's own phone badge.

Nextdoor

Buyers are probably neighbours. A second number keeps it friendly but separate if a sale goes badly and you still see them around.

Mercari and Poshmark

These handle shipping inside the app, so you rarely need a number. For local pickups, use your second number.

What It Costs

A TINE number costs $5 a month, or $49.99 a year (about $4.17 a month), with some calling and texting credit included. If you only sell now and then, take the monthly plan and cancel when you've cleared out the garage.

Frequently Asked Questions

Can you hide your name on Facebook Marketplace?

Outside the EU, EEA and Switzerland, no. You sell from your Facebook account and buyers can see your Marketplace profile. You can limit what else they see by locking down your profile.

Does Facebook Marketplace show your phone number?

Marketplace listings don't include a phone number unless you type one into the listing. The risk comes when buyers ask for it so they can text or call you.

Can I use a second number on Craigslist?

Yes, as the number you show buyers. For Craigslist's own phone verification, use your mobile, because Craigslist doesn't support VoIP numbers for that step. Your verification number isn't shown on your posts.

Is it safe to give my address to a Marketplace buyer?

Only when you have to. Meet in public where you can. If they must collect from your home, share the address late, and don't be alone.

What should I do if a buyer harasses me?

Stop replying, block them, report them on the platform, and keep screenshots. If they have your second number, you can stop using it. If you feel unsafe, contact the police.

The Bottom Line

You can't be fully anonymous on Facebook Marketplace, but you can make sure a sale never leads a stranger to your door. Lock down your profile, keep chats on the platform, meet in public, and give buyers a second number instead of your own.
