How to Change Your Phone Number on iPhone

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

Your iPhone's phone number is assigned by your wireless carrier — AT&T, Verizon, T-Mobile, or whoever you pay for service. Apple does not control it. To change your number, you contact your carrier directly, either through their website, their app, by phone, or by visiting a store. The process takes minutes to hours depending on the carrier and method you choose.

Once your carrier changes the number in their system, your iPhone automatically receives the update. You do not need to do anything in iPhone settings. The new number appears in the Phone app and in your device settings within a few minutes.

Key Takeaways

Your wireless carrier controls your phone number, so you must contact them to change it — AT&T, Verizon, T-Mobile, or your prepaid provider.
Most carriers let you change your number online through their website or app without calling or visiting a store.
Some carriers charge a fee to change your number, usually between $15 and $30, though some waive it if you have a valid reason.
Your iPhone updates automatically once the carrier processes the change; you do not need to adjust any settings yourself.
Changing your number does not affect your iCloud account, Apple ID, or any data on your phone.

How to change your number through your carrier's website or app

Most carriers offer the fastest route through their own website or mobile app. Log in with your account credentials, look for a section labeled "Manage My Number," "Change Number," or "Phone Number Settings," and follow the prompts. The carrier will ask you to confirm your identity, may ask why you want to change the number, and will show you available numbers in your area code or a different one if you request it.

Verizon's app and website both have a "Change Number" option under Account settings. AT&T's website includes a "Change Your Number" tool in the Account section. T-Mobile's app and website have similar options under Account or Services. If you use a prepaid carrier like Boost Mobile, Cricket, or Metro by T-Mobile, the process is the same — log into your account and look for number management options.

After you select a new number and confirm, the carrier processes the change. This usually takes effect within minutes, though some carriers may take up to a few hours. You will receive a confirmation text or email with your new number.

Changing your number by phone or in person

If you prefer to speak with someone, call your carrier's customer service number. You can find it on your bill, on the back of your SIM card, or on the carrier's website. Have your account number and a form of ID ready. The representative will verify your identity, explain any fees, show you available numbers, and process the change over the phone.

You can also visit a carrier store in person. Bring your ID and your phone. A staff member can change your number on the spot, usually in under 10 minutes. This method works well if you want to see available numbers before choosing or if you have questions about the process.

What happens to your data and accounts when you change your number

Changing your phone number does not affect anything on your iPhone itself. Your photos, messages, contacts, and apps all stay exactly where they are. Your iCloud account and Apple ID remain the same because they are tied to your email address, not your phone number.

What does change is how people reach you by text or phone call. You will need to tell your contacts your new number. Some apps that use your phone number for two-factor authentication — like banking apps or social media accounts — may ask you to update your number in their settings, but this is separate from changing your carrier number and happens only if you choose to update those accounts.

Fees and reasons carriers may charge

Most carriers charge between $15 and $30 to change your number. Verizon, AT&T, and T-Mobile all charge a fee, though the exact amount varies by plan and region. Some carriers waive the fee if you have a legitimate reason, such as harassment, spam calls, or a data breach affecting your number.

If you are switching carriers entirely — moving from Verizon to T-Mobile, for example — you can usually keep your current number through a process called number porting. This is different from changing your number and often has no fee. Ask your new carrier about porting when you switch.

How to verify your new number is active on your iPhone

After your carrier processes the change, open the Settings app on your iPhone. Tap "Phone" and look at the line labeled "My Number." Your new number should appear there within a few minutes. If it still shows your old number after an hour, restart your iPhone by turning it off and back on. This forces your phone to reconnect to the carrier's network and refresh the information.

You can also check by opening the Phone app and looking at the number displayed at the top of the Contacts tab. Another way to confirm is to call yourself from another phone — if your iPhone rings, the new number is active.

What to do if your carrier won't change your number

Some carriers have restrictions on how often you can change your number. If you changed it recently, they may require you to wait 30 to 90 days before changing it again. If you hit this limit, ask the carrier when you will be may be able to access to change it next.

If you believe the carrier is wrongly refusing your request, ask to speak with a supervisor or file a complaint with the Federal Communications Commission (FCC). The FCC handles complaints about wireless carriers and can investigate if a carrier is not following its own policies.

Frequently Asked Questions

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

No. Your Apple ID is tied to your email address, not your phone number. Your iCloud data, backups, and all Apple services continue to work exactly as before. You do not need to update anything in Apple settings.

Can I keep my old number if I switch to a different carrier?

Yes, through a process called number porting. When you sign up with a new carrier, tell them you want to port your number from your old carrier. The new carrier handles most of the process. There is usually no fee, though some carriers charge a small amount. It typically takes one to three business days.

Will my text messages or iMessage history disappear if I change my number?

Your message history stays on your iPhone. However, people texting your old number will not reach you anymore. If someone tries to text your old number, the message may bounce back or go to whoever the carrier assigns that number to next. Let your contacts know your new number so they can update it in their phones.

What if I change my number and then want to change it back?

You can change your number as many times as your carrier allows, but most carriers require you to wait 30 to 90 days between changes. If you want your old number back immediately, ask your carrier if it is still available. If someone else has been assigned it, you cannot get it back.

Do I need to update my number anywhere else after changing it on my iPhone?

You should update your number with any service that uses it for two-factor authentication or account recovery — banks, email providers, social media accounts, and work systems. Your iPhone itself does not need any updates. Check the settings of apps that send you codes or alerts to make sure they have your new number.
