What X (Twitter) checks
Verification is an SMS code. X refuses ranges it classifies as VoIP and limits how many accounts one number can verify. A real mobile allocation from a trusted country is accepted; cheap ranges are refused with « this phone number cannot be used » more often than on other platforms.
- The lock. A new account that follows, posts links or is created over a VPN is locked and asks for a phone. Verifying unlocks it immediately.
- SMS two-factor is a paid feature on X. Use an authenticator app or a security key instead; it is safer anyway.
- Discoverability. « Let people who have your phone number find you » is a setting. Turn it off.
Which line and country to pick
Take a mobile line from the United Kingdom, the United States or Germany. This is not the place for a budget range.
Verify before you get locked. Adding the number in Settings → Account information on day one avoids the lock altogether, and a number added calmly is questioned less than one added under a lock.
Step by step
- Pick the line. Choose a mobile line in United Kingdom or another recommended country. The exact price, activation included, is shown before you pay.
- Pay in crypto. Send any of 8 cryptocurrencies to a one-time deposit address. The line is live about a minute after the payment confirms; no e-mail, no document.
- Enter the number in X (Twitter). Type the number where X (Twitter) asks for it and request the code.
- Read the code in the panel. The SMS lands in your inbox with the code extracted and copyable. Developers get it on a webhook.
- Lock the account. Set Authenticator app or security key so the account does not depend on the number alone.
If X (Twitter) refuses the number. It is the range, not the line. Ask for a swap — free within 7 days — and you get a number from a different carrier block, with the remaining period carried over.
Keeping the account
- Two-factor with an authenticator or key, since SMS two-factor is behind a subscription and depends on the number anyway.
- Keep the line while the account matters; X re-asks on every lock.
- One number per account. Reusing it across accounts is the fastest way to get all of them flagged together.

Questions
Does X accept virtual phone numbers?
Real mobile allocations from trusted countries, yes. X is strict with VoIP-classified and cheap ranges; a UK, US or German mobile line is what we recommend.
Why does X want my phone number after signup?
New accounts are locked for suspected automation until a number is verified. Verifying unlocks them at once. Adding the number before the lock avoids it.
Can I use SMS two-factor on X with this number?
Only on a paid plan. Use an authenticator app or a security key instead; neither depends on the number.
Can people find me on X by this number?
Only if discoverability by phone number is on. Turn it off in the privacy settings.
How many X accounts can one number verify?
Few, and flagged accounts lower the limit. Use one line per account.
