Change your number through your carrier, not through iPhone settings
Your phone number is managed by your wireless carrier — AT&T, Verizon, T-Mobile, or whoever you pay for service. iPhone has no setting that changes your number. To get a new number, you contact your carrier directly by phone, through their website, or in person at a store. The carrier makes the change on their end, and your iPhone receives the new number automatically within a few hours.
The process is free if you're within your contract terms, though some carriers charge a fee if you change numbers too frequently in a short period. Most carriers allow one free change per account per year, then charge $15 to $30 for additional changes. Before you call, know that the carrier will ask why you want to change — they track this partly to catch fraud, partly to see if they can solve the underlying problem instead.
Key Takeaways
- Contact your wireless carrier by phone, website, or store visit to request a number change; iPhone itself has no number-change setting.
- The carrier processes the change on their network, and your iPhone automatically receives the new number within hours — no action needed on your phone.
- Most carriers allow one free number change per year, then charge $15 to $30 for each additional change.
- After the change takes effect, update your number in contacts, passwords, and two-factor authentication settings for accounts that use your phone number.
How to request a number change from your carrier
Call your carrier's customer service line — the number is on your bill or on their website. Tell them you want to change your phone number. They will verify your account by asking for your account number, the last four digits of your Social Security number, or a PIN you've set up. Have your account information ready to speed this up.
Ask the representative whether the change is free under your plan. If you've already used your free annual change, confirm the fee before you proceed. Some carriers let you choose your new number from available options in your area code; others assign one to you. If you have a preference, ask whether selection is available.
The carrier will give you a confirmation number and tell you when the change takes effect — usually within 24 hours, sometimes the same day. Write down the confirmation number. Your iPhone will not prompt you or show a notification; the new number simply becomes active on the carrier's network. You can verify the change by opening Settings > General > About and looking at the phone number listed there, or by calling yourself from another phone.
Update your accounts and contacts after the change
Once your new number is active, update any account that uses your phone number for login or recovery. This includes email accounts, banking apps, social media, and work systems. Go into each account's security or settings section and update the phone number field.
For accounts that use your phone number as a second factor (two-factor authentication), update those first. If you try to log in to an account before updating the number there, you may not receive the verification code on your new number and could lock yourself out temporarily.
Update your contacts list so people have your new number. You can text or call people individually, or send a group message. Add your new number to your email signature if you use one for work. If you have an Apple ID, sign in to iCloud.com and update the phone number in your account settings there as well.
What happens to texts and calls to your old number
Once your number is reassigned to another person, texts and calls to your old number go to that new owner. This happens within days or weeks of your change. You cannot retrieve messages sent to the old number, and the new owner will receive them instead.
If you're worried about accounts still using your old number, prioritize updating financial institutions, email providers, and any service where someone could use your phone number to reset a password. For less critical accounts, update them over the next week or two as you remember.
Changing your number on a family plan
If you're on a family plan, you can change your individual number without affecting anyone else's. Call the carrier and specify which line on the account you want to change. The account holder (usually a parent or spouse) may need to authorize the change depending on the carrier's policy, but the process is otherwise the same.
If you're the account owner and want to change your own number, you can do it directly. If you want to change someone else's number on your family plan, you'll typically need their permission or have them call the carrier themselves.
If you need to keep your old number
If you're moving to a new carrier and want to keep your current number, ask about number porting. This is different from changing your number with your current carrier. When you port a number, your current carrier releases it to the new carrier, and you keep the same number on the new network. This process takes a few days and requires information from both carriers.
Number porting is free by law. Your new carrier will handle most of the paperwork; you just need to provide your account number and billing address from your old carrier. During the port, your service may be down for a few hours, so plan the switch for a time when you don't need your phone urgently.
Frequently Asked Questions
Will changing my number affect my iCloud or Apple ID?
No. Your Apple ID is tied to your email address, not your phone number. Changing your phone number does not affect iCloud, FaceTime, or iMessage. However, you should update the phone number in your Apple ID security settings so Apple can reach you if there's suspicious activity on your account.
Can I change my number online instead of calling?
Most carriers let you request a number change through their website or mobile app. Log into your account, look for account settings or phone number management, and follow the prompts. If the option isn't available online, you'll need to call or visit a store.
What if I change my mind after the carrier processes the change?
Contact your carrier immediately. If the change hasn't taken effect yet, they may be able to cancel it. Once the new number is active and your old number has been reassigned, you cannot get the old number back. You would have to request a different new number instead.
Do I need to do anything on my iPhone after the number change?
No. Your iPhone automatically receives the new number from the carrier's network. You don't need to restart it, update settings, or enter anything manually. Just verify the change took effect by checking Settings > General > About.
Will my contacts be able to reach me during the number change?
During the few hours the change is processing, your old number may not work reliably. Calls and texts could fail or be delayed. Once the new number is active, your old number stops working entirely. Tell people your new number before you request the change if possible.
