Confirming a Facebook account with a US phone number

What Facebook’s help center says about your number

Read on facebook.com/help and facebook.com/terms.php on November 13, 2026. No voice-call code is documented.

Why your two-factor number can’t also reset your password

Facebook says that, for security reasons, the mobile number you use for two-factor authentication can’t be used to help you reset your password. A reset has to come through some other contact on the account: your email or a second number.

So decide what job a rented number does before you add it. As the two-factor number, it will be texted a 6-digit code each time someone signs in from a phone or browser Facebook doesn’t recognize, and it has to stay yours for as long as two-factor stays on. As a reset or checkpoint contact, it only matters on the day you need it, which is the day you least want it to have ended. Either way, put your own email on the account; Facebook recommends that everyone does.

Two-factor doesn’t have to be a text. Facebook also accepts an authenticator app, a security key, approval from a device that’s already signed in, and printed recovery codes, none of which depend on a number.

Checkpoints and the request to confirm your number again

Facebook sometimes asks you to verify the account before you can go on, and its help calls these checkpoints. A confirmed number or email, it says, gives you another way to pass one. It may also ask you to confirm a number you added earlier, and one reason it lists is that “time has passed” since you last added or updated it. Both arrive as a code to the number, at a time you didn’t choose.

Private or incognito windows, or a browser that clears its history on close, make Facebook treat every visit as a new device, so you are asked for a code at each sign-in. Use a normal window if the number is your two-factor number.

Your contact details now sit in Meta’s Accounts Center, which Facebook shares with Instagram, so a change you make there is not Facebook-only. The Instagram guide covers its side: WhatsApp codes and email sign-up.

Confirming Facebook with a number from us

1. Get a number first

   Buy one on the home page. Keep its page open in another tab.

2. Enter it in Facebook’s sign-up form

   In the mobile number or email field, type the country code 1 before the ten digits, as Facebook asks. Finish the form; Facebook texts a code to confirm the account.

3. Type the code from the number’s page

   It appears there on its own, with a copy button. If nothing comes, use Send SMS again on Facebook’s screen.

Our numbers are non-VoIP, and Facebook’s help center says nothing about which number types it takes, so the decision is Facebook’s; if its text never arrives, cancel the number within 24 hours.

Adding and removing the number, and how long to rent it

The contact list is under Settings and privacy, Settings, Accounts Center, Profiles and personal details, Contact info. Add new contact, then Add mobile number or add an email; to take a number off, select it and choose Delete number.

1 week ($7.99) suits the common case: confirm the account with the number, add and confirm your own email from that same screen, then delete the number before the rental ends. Once a rental ends, the number can be given to someone else, so it shouldn’t stay on your account by accident.

1 year ($34.99) if you keep it as your two-factor or checkpoint number. Facebook will come back to it, and the risk of an ended number is that its next holder receives the codes meant for you.

If Facebook’s code doesn’t arrive

At sign-up, Facebook suggests, in this order:

1. Check the number you typed, and fix it with Update contact info.
2. Tap Send SMS again.
3. Confirm the account with your email address instead of a mobile number.

At a two-factor sign-in, Facebook says text codes can be delayed by the network, so wait a few minutes. It also says codes stop if text messages from Facebook have been turned off in your settings. If the code still doesn’t come, approve the sign-in from a device that’s already logged in, enter a recovery code, or choose I don’t have my phone and confirm your identity, which Facebook says it reviews typically within 1 to 2 business days.

If no text from Facebook reaches a number you just bought, cancel it within 24 hours for a refund (refund terms).

Questions people ask

Can I create a Facebook account without a phone number?

Yes. Facebook says that if you don’t have a mobile number you can sign up with an email address instead. You need to confirm one or the other to finish creating the account.

What if my mobile number is linked to another Facebook account?

Facebook says that if a message tells you an account already exists with your number, you may need to wait a few days before you can add it to yours. If it isn’t your account, use a different number or your email.

Why does Facebook ask for a code every time I log in?

Two-factor codes are asked for on devices and browsers Facebook doesn’t recognize. Private browsing, or clearing your history whenever the browser closes, makes every visit look new.

What happens if I never confirm my Facebook account?

Facebook’s terms allow it to disable an account that isn’t confirmed after registration. Confirm with your email or a number you will still have.

How do I log in to Facebook with a phone number?

Enter the whole number including the country code, 1 for a US number, and leave out extra zeros, plus signs and other symbols, as Facebook’s login help describes.
