In short
X asks for a number at sign-up or to unlock an account. A one-time activation in @HushNumBot or on the website is enough for that code. SMS two-factor authentication in X is only for Premium subscribers, so an authenticator app protects the account better than a number.
In X a phone number is needed in two situations: at sign-up, if the service decided to check a new account, and when the account is locked and X asks you to prove a person runs it. Both need just one code, and long-term protection is better built without SMS.
When X asks for a phone number
- at sign-up, if the system decided to check the new account;
- when the account is temporarily locked and unlocking needs a phone confirmation;
- when you change details or after a suspicious sign-in, if a number is in the account.
How to get the X code
- In the bot or the web account, choose Twitter/X and a country.
- Buy the number and enter it in the form with the country code.
- Request the code and wait for the SMS in your order.
- Enter the code in X. If no code arrives within 15 minutes, the money returns to your balance.
Two-factor authentication in X without a number
Since 2023, X has kept SMS two-factor authentication for Premium subscribers only. Everyone else can use an authenticator app or a security key. That is good news: you can protect the account without tying it to a phone number, and a virtual number is needed only for a one-off confirmation.
If X does not accept the number
X limits how many accounts one number can confirm and may reject numbers that are used often. If the form shows an error right away, take another number or country. The general checklist is in SMS code not received.
Do you need a rental?
Usually not: sign-up and unlocking need one code. A rental helps if the number will be the account's main contact, you expect repeat checks and you do not want an authenticator app.
Frequently asked questions
Can I turn on SMS two-factor in X with a virtual number?
SMS two-factor in X is only for Premium subscribers. For everyone else an authenticator app is more reliable: it does not depend on a number.
What if my X account is locked and asks for a phone?
Get a number in the bot or the web account, enter it in the unlock form and wait for the code in your order. After you sign in, check the security settings.
Why does X say the number cannot be used?
The number may already have been used for other accounts or fall under X's limits. Take another number or country.
Check Hush SMS on one order: if the code does not arrive within 15 minutes, the money returns to your balance automatically.
