• One phone number per account. Even with a dual SIM phone, you choose one
• The same number can be added to up to 10 accounts, and each one receives password reset and login verification texts
• A phone number gives access to login verification and lets contacts find you if they have your number
• If an account is inactive for 45 days or more and someone else verifies the same number on a new account, X detaches it from yours and notifies you
• Your email isn't shown on your profile, but people who already have it can find you unless you turn off Let others find me by my email address

X suggests updating your number before you change phone or device, and wiping personal data from the old one.

• The email is already on another X account. X allows one address per account, so use a different address or change the other account's email first
• The number is "already associated" with another account. X says it may have belonged to someone else before you, and that the old owner gets no access to your account
• No verification text: if you've blocked texts from 40404 before, unblock it and request a new code. X notes some people are having SMS trouble
• The new email shows as unconfirmed: find the confirmation email and select Confirm now
• You've lost the old phone: sign in to x.com on a computer, open your Apps settings and revoke access for apps connected through that phone
