You can change your iPhone's phone number through your carrier, not through Apple

Your phone number is assigned and managed by your wireless carrier—Verizon, AT&T, T-Mobile, or whoever you pay for service. Apple's iPhone is just the device that displays it. To change your number, you contact your carrier directly, either online, by phone, or in person at a store. The process takes a few minutes to a few hours depending on the carrier and method you choose.

Once your carrier has switched your number, your iPhone will automatically detect the change and display the new number in Settings. You do not need to do anything on the phone itself to make the switch happen.

Key Takeaways

  • Your wireless carrier controls your phone number, so you must contact them to change it—Apple cannot do this for you.
  • Most carriers let you request a number change online through their account portal, by calling customer service, or by visiting a physical store.
  • The change usually takes effect within minutes to a few hours, and your iPhone will show the new number automatically in Settings > Phone.
  • Some carriers charge a fee for changing your number; check your carrier's policy before you request the change.
  • If you want to keep your current number when switching carriers, you will need to request a port-out authorization code instead of a number change.

How to change your number through your carrier's website

Most major carriers offer online account management where you can request a number change without calling. Log into your carrier's website or app using your account credentials. Look for a section labeled "Phone Number," "Manage Phone Number," or "Change Number"—the exact wording varies by carrier.

Select the line you want to change (if you have multiple lines on your account), then choose a new number from the available options your carrier shows you. Some carriers let you search for numbers with a specific area code or prefix. Confirm the change, and the carrier will process it. Write down your new number and any confirmation code provided.

Check your iPhone's Settings app after 15 minutes to an hour. Go to Settings > Phone > My Number to see if the new number appears. If it does not show up within a few hours, restart your iPhone by turning it off and back on.

Changing your number by calling your carrier

If you prefer to speak with someone, call your carrier's customer service line. The number is usually on your bill, on the back of your SIM card, or on the carrier's website. Tell the representative you want to change your phone number and have your account information ready—usually your account number, PIN, or the phone number associated with the account.

The representative will confirm your identity, show you available numbers, and process the change over the phone. Ask them to confirm the new number before you hang up and to give you a reference number for the change. The new number typically takes effect within minutes but can take up to a few hours.

Changing your number in person at a carrier store

You can also visit a physical store operated by your carrier and request a number change at the counter. Bring a photo ID and your account information. A store employee will look up your account, show you available numbers, and process the change when ready. This method is useful if you want to see available numbers in your preferred area code or if you have questions the representative can answer face-to-face.

The change usually takes effect while you are still in the store or within a few minutes of leaving. Your iPhone will detect the new number and display it in Settings shortly after.

What to expect after your number changes

Once your carrier has processed the change, your iPhone will automatically recognize the new number. You can see it in Settings > Phone > My Number. Your contacts, messages, and apps will continue to work normally—the change only affects the phone number associated with your line.

You will need to tell your contacts your new number so they can reach you. If you use your phone number for two-factor authentication on accounts like email, banking, or social media, update those services with your new number so you can still receive verification codes.

Fees and restrictions for changing your number

Some carriers charge a fee to change your number, while others offer it for free. Verizon, AT&T, and T-Mobile policies vary and change over time, so check your carrier's website or ask when you request the change. The fee, if there is one, is usually between $15 and $25.

Most carriers let you change your number as often as you want, but some may limit how frequently you can do so—for example, once per account per year. If you have recently changed your number and want to change it again, ask your carrier whether there are any restrictions.

When to port your number instead of changing it

If you are switching to a different wireless carrier and want to keep your current phone number, you do not change your number—you port it. Porting transfers your number from one carrier to another. Contact your new carrier and ask for the process; they will handle most of the work. You will need a port-out authorization code from your current carrier, which you can request online or by phone.

Porting usually takes one to three business days. During that time, your service may be interrupted briefly. Once the port is complete, your iPhone will show your original number on the new carrier's network.

Frequently Asked Questions

Will changing my number affect my iCloud account or Apple ID?

No. Your Apple ID is tied to your email address, not your phone number. Changing your iPhone's phone number does not affect your Apple ID, iCloud, or any Apple services. If you use your phone number as a recovery method for your Apple ID, you can update that separately in Settings > [Your Name] > Password & Security.

Can I choose a specific phone number when I change it?

Most carriers show you a list of available numbers and let you choose from them. Some carriers let you search by area code or prefix. You cannot request a completely custom number, but you usually have several options to pick from. If none of the available numbers appeal to you, you can ask the carrier to show you more options.

How long does it take for my new number to show up on my iPhone?

Usually between 15 minutes and a few hours. Your carrier processes the change first, then your iPhone detects it automatically. If your new number does not appear in Settings > Phone > My Number within a few hours, restart your iPhone. If it still does not show up after 24 hours, contact your carrier to confirm the change went through.

What happens to my text messages and calls after I change my number?

Your old messages and call history stay on your iPhone. Incoming calls and texts will come to your new number going forward. People trying to reach your old number will not be able to contact you, so tell your contacts your new number as soon as possible.

Can I change my number if I am in the middle of a contract?

Yes. Changing your phone number is different from canceling your service or switching carriers. You can change your number while keeping the same carrier and the same contract. There is no penalty for doing so, though your carrier may charge a fee for the change itself.
