In short
Facebook asks for a number at sign-up or during a security check, and later may send a code to the same phone again. For a one-off confirmation a one-time activation in @HushNumBot or on the website is enough. If you need the account for a long time, take a rental: the repeat check reaches the same number.
Facebook rarely stops at one code. Meta may ask you to confirm the number at sign-up, after a device change or when its security system sees unusual activity. So choose the number with the question in mind: will you need the account after the first sign-in?
When Facebook asks for a phone
- at sign-up, if you give a number instead of an email or Facebook asks for confirmation;
- during a security check: a new device, unusual activity, a suspected break-in;
- when you turn on two-factor authentication by SMS;
- when you recover access, if the number is in the account.
How to get the Facebook code
- In the bot or the web account, choose Facebook and a country.
- Buy the number and enter it in the form with the country code.
- Request the code only after the number has been issued.
- Wait for the SMS in your order and confirm the number.
Why Meta may not accept a number
Meta checks how many accounts are already linked to the number, whether the number's country matches other signals and how often the code was requested. If the form says right away that the number cannot be used, take another number or country instead of repeating the request. A code that did not arrive within 15 minutes costs nothing: the money returns to your balance.
Facebook, Instagram and the Accounts Center
Facebook and Instagram can be joined in the Meta Accounts Center, and then the number becomes a shared contact for both. If you link the accounts, keep in mind that losing the number affects both. For Instagram, see virtual number for Instagram and TikTok.
What to do after sign-up
- add an email you will always have access to;
- for two-factor authentication, choose an authenticator app rather than SMS to a one-time number;
- if the number was a one-time activation, replace it in the settings with a permanent or rented one.
Frequently asked questions
Can I use one number for Facebook and Instagram?
Yes, if you join the accounts in the Meta Accounts Center. But then you need the number for a long time: a check sends the code to it for both accounts.
Why does Facebook ask for the code again a few days later?
That is how Meta's security works: it may ask for confirmation when you sign in from a new device or after unusual activity. A number rental covers these cases.
What if Facebook says the number cannot be used?
Take another number or another country. Repeating with the same number usually does not help.
Check Hush SMS on one order: if the code does not arrive within 15 minutes, the money returns to your balance automatically.
