Change your number through your carrier, not through iPhone settings

Your phone number is managed by your carrier — the company that provides your cellular service — not by Apple or your iPhone itself. To change your number, you contact your carrier directly by phone, through their website, or by visiting a store. The iPhone has no setting that changes your number. Once your carrier completes the change, your phone will automatically use the new number within a few hours.

The process is straightforward and usually free if you have been with your carrier for at least a few months. Some carriers charge a small fee if you change your number frequently or within a short time of your last change. The entire process typically takes between 15 minutes and 24 hours, depending on your carrier and whether you do it online or by phone.

Key Takeaways

  • Contact your carrier — not Apple — to change your phone number; your carrier is Verizon, AT&T, T-Mobile, or another company that bills you monthly.
  • You can request a number change by phone, online through your carrier's website or app, or by visiting a physical store location.
  • The change is usually free, but some carriers charge a fee if you have changed your number multiple times in a short period.
  • After your carrier processes the change, your iPhone will receive the new number automatically within a few hours; no action is needed on the phone itself.
  • Before changing your number, update your contacts with your new number and notify people who reach you regularly so they have the correct information.

How to request a number change from your carrier

The fastest way to change your number is to call your carrier's customer service line. The number is on your bill, on your carrier's website, or on the back of your SIM card. Tell the representative you want to change your phone number. They will ask why you want to change it (you do not need a specific reason) and whether you want to keep your current number as a backup or have it released. The process takes about 10 to 15 minutes.

If you prefer not to call, most carriers offer online number changes through their website or mobile app. Log in to your account, look for a section called "Manage My Number," "Change Number," or "Phone Settings," and follow the prompts. The online process usually takes 5 to 10 minutes and gives you the new number immediately, though it may take a few hours to activate on your phone.

You can also visit a physical store location for your carrier. Bring a photo ID. A representative will process the change in person, which usually takes 15 to 30 minutes. This option is useful if you have questions or want to discuss options before making the change.

What happens after your carrier processes the change

Once your carrier completes the number change, your iPhone will receive the new number automatically. You do not need to restart your phone, update settings, or contact Apple. The new number will appear in your iPhone's settings under Settings > Phone > My Number within a few hours. You can verify the change by checking that location or by calling your own number from another phone.

During the transition period — usually a few hours — calls and text messages to your old number may still reach you. After the transition is complete, your old number will no longer work on your phone. Your carrier may reassign your old number to another customer, so do not share it with anyone after the change.

Costs and restrictions on changing your number

Most carriers do not charge a fee to change your number once per year or even once every few months. However, if you change your number frequently — more than once or twice per year — some carriers charge $15 to $25 per change. Check your carrier's policy before requesting the change if you are concerned about fees.

Some carriers have restrictions based on your account status. If you are in the middle of a contract or have an outstanding balance, your carrier may ask you to settle the balance before processing the change. If you are on a prepaid plan, you can usually change your number without restrictions. Ask your carrier about any conditions that apply to your specific account.

Notifying your contacts and updating your information

Before you change your number, make a list of people and services that have your current number. This includes family, friends, employers, banks, doctors, and any online accounts that use your phone number for two-factor authentication. After your carrier processes the change, contact these people and services to give them your new number.

For online accounts — email, banking, social media, and others — update your phone number in your account settings. This is especially important for accounts that use your phone number to verify your identity or send security codes. If you do not update these accounts, you may not be able to log in or recover your account if you forget your password.

If you use your old number for work or business, give your new number to clients, colleagues, and anyone who contacts you regularly. Consider setting up a voicemail message on your old number (if your carrier allows it) that directs callers to your new number, though this only works for a limited time after the change.

Changing your number on a family plan

If your iPhone is part of a family plan, you can change only your own number without affecting other family members' numbers. Call your carrier or log into your account and request a change for your specific line. The carrier will process the change for only that line while leaving other numbers on the plan unchanged.

If you are the account holder for a family plan and want to change the number on another family member's line, you can request it, but some carriers require the account holder's permission or the line holder's consent. Check your carrier's policy or ask during the call.

If you change your mind or need to reverse the change

If you change your number and then realize you made a mistake, contact your carrier immediately. Most carriers allow you to reverse the change within 24 to 48 hours at no cost. After that window closes, reversing the change may not be possible, or your carrier may charge a fee. The sooner you contact them, the better your chances of getting your old number back.

If your old number has already been reassigned to another customer, your carrier cannot restore it. In that case, you will need to keep your new number and notify your contacts of the change.

Frequently Asked Questions

Do I need to do anything on my iPhone to change my number?

No. Your iPhone has no setting that changes your number. You contact your carrier, they process the change, and your phone receives the new number automatically. You do not restart your phone, update settings, or contact Apple.

Will I lose my text messages or photos if I change my number?

No. Changing your number does not affect anything stored on your iPhone. Your messages, photos, contacts, and apps remain on your phone. Only the phone number associated with your account changes.

Can I change my number if I am on a prepaid plan?

Yes. Prepaid carriers usually allow number changes without restrictions. Contact your carrier by phone, through their app, or online to request the change. The process is the same as for postpaid plans.

How long does it take for my new number to work?

Your carrier usually activates the new number within a few hours. In rare cases, it may take up to 24 hours. You can check if the change is complete by looking in Settings > Phone > My Number or by calling your own number from another phone.

What should I do with my old number after I change it?

Do not share your old number with anyone. Your carrier will reassign it to another customer, and any messages or calls sent to that number will reach someone else. Update all your contacts with your new number before or shortly after the change.
