What you can actually change about your caller ID on iPhone

Your carrier controls what name and number appear when you call someone — Apple cannot override that. What you can change on your iPhone is the name that appears in your own Contacts app next to your phone number, and you can hide your number from individual calls using a built-in setting. You cannot change the actual phone number the carrier broadcasts, and you cannot change what name the carrier displays (that comes from their records, not your phone).

If you want callers to see a different name, you need to contact your carrier and ask them to update the name associated with your account. If you want to block your number from showing up on outgoing calls, you can do that directly on your iPhone in Settings.

Key Takeaways

  • Your carrier controls the name and number that appears to people you call — your iPhone cannot change what they see.
  • To change the name your carrier displays, contact your phone company and ask them to update your account information.
  • To hide your number on individual calls, go to Settings > Phone > Show My Caller ID and toggle it off before you call.
  • The name in your own Contacts app next to your phone number is local to your phone and does not affect what others see.

Contacting your carrier to change your displayed name

Your phone company maintains a database with your account name. When you call someone, their phone receives your number from the carrier's network, and their phone looks up the name associated with that number in the carrier's directory. Changing what appears requires the carrier to update their records.

Call your carrier's customer service number (it is on your bill or their website) and ask to update the name on your account. Have your account number and a form of ID ready. The process usually takes a few minutes on the call, though it can take 24 to 48 hours to show up on other people's phones. Different carriers handle this differently — some allow you to set a business name, some only allow your legal name — so ask what options they offer.

If you are on a family plan, the primary account holder may need to make the change. If you are on a prepaid plan, some carriers do not allow name changes at all.

Hiding your number on calls using iPhone Settings

If you want your number to appear as "Unknown" or "Private" to the person you are calling, you can turn off caller ID for all calls or for individual calls.

To hide your number on all outgoing calls: Open Settings, tap Phone, scroll down to Calling Line Identification, and tap Show My Caller ID. Toggle it off. From that point on, your number will not display when you call anyone (unless you toggle it back on).

To hide your number on a single call: Open the Phone app, dial the number, then before you tap Call, tap the three dots (more options), and toggle off Show My Caller ID. Tap Call. That number will not see your caller ID for that call only.

Note that some businesses and government agencies will not accept calls from blocked numbers, and some may interpret a blocked number as a spam call. Emergency services (911) will always receive your real number regardless of this setting.

Why your carrier name might not match what you set

If you have changed the name in your iPhone's Contacts app next to your own phone number, that name only appears on your phone when you look at your own number. It does not broadcast to other people. When someone calls you, they see the name your carrier has on file, not the name you entered locally.

Similarly, if you have a business name you want to display, your carrier has to have that name in their system. Changing it in your iPhone's Notes app, your email signature, or anywhere else on your phone will not change what callers see.

What to do if your carrier will not change your name

Some carriers, especially prepaid services, do not allow account name changes. If your carrier refuses, you have limited options on the phone side — the restriction is at the carrier level, not the iPhone level.

You can ask the carrier if there is a workaround, such as updating your account through their online portal or visiting a physical store. Some carriers allow changes online that they will not do over the phone. If the carrier genuinely will not change it, the only way to display a different name is to switch to a carrier that allows it.

Caller ID spoofing and what is illegal

Changing your displayed name through your carrier is legal. Spoofing — making your call appear to come from a number that is not yours — is illegal under federal law in the United States. Do not use apps or services that claim to let you call from a different phone number or make your call appear to come from a business you do not own.

If you are a business and want to display your business name instead of your personal name, that is legitimate and your carrier can set it up. If you want to hide your number entirely, that is also legitimate. Anything that makes your call appear to come from a different person's or business's number is illegal.

Frequently Asked Questions

Can I change my caller ID name without calling my carrier?

No. Your carrier controls what name displays to other people. You can hide your number entirely through iPhone Settings, but you cannot change the name that appears without contacting your carrier and asking them to update their records.

Will changing my caller ID name affect my voicemail greeting?

No. Your voicemail greeting is separate from your caller ID name. Changing one does not change the other. You can update your voicemail greeting through the Phone app by opening Voicemail, tapping Greeting, and selecting Custom.

Does hiding my caller ID affect text messages?

No. Hiding your caller ID through Settings only affects phone calls. Text messages always show your phone number to the recipient, and there is no built-in way to hide it for SMS or iMessage.

What if I am getting calls from someone spoofing my number?

Report it to your carrier and to the Federal Communications Commission (FCC) at fcc.gov/complaints. Do not try to change your number in response — spoofing is illegal and the carrier can investigate. You can also block the spoofed calls on your iPhone by adding them to your blocked list in the Phone app.

Can I set different caller IDs for different contacts?

No. Your iPhone displays the same caller ID to everyone you call. Your carrier broadcasts one name and number associated with your account. You cannot set it to display differently to different people.
