Verifying a phone number for Facebook Marketplace
Quick answer
Facebook may ask you to confirm a phone number before you can list items or message buyers on Marketplace, especially on a new account. The code arrives by SMS, and the number isn't shown to buyers. If your code doesn't arrive or Facebook rejects the number, try another mobile number. A Noir SMS number can usually receive the code for your own account. Keep chats inside Messenger and never share your personal number or verification codes with buyers.
Marketplace is one of the busiest places to buy and sell locally, which also makes it a target for scams. Phone checks are Facebook's way of slowing down fake seller accounts.
Why the check appears
- New or recently created Facebook accounts.
- Accounts that haven't confirmed any contact info.
- Activity that Facebook's systems see as unusual, like many listings in a short time.
Verifying
Follow the prompt in Marketplace or go to Accounts Center > Personal details > Contact info and add a phone. Enter the SMS code. If you verify with a separate number, add a backup method too, because a temporary number is recycled later.
The "verify with a code" scam
A common trick: a "buyer" asks you to read them a code sent to your phone to "prove you're real". That code usually lets them take over a Google Voice number or one of your accounts. Never read a verification code to anyone.
Frequently asked questions
Do buyers see my phone number?
No. Marketplace conversations happen in Messenger and your number stays private unless you share it.
Can I use Marketplace without verifying a phone?
Sometimes, but Facebook can require it before you list or message. Confirming an email alone isn't always enough.
