How to Hide Caller ID on iPhone 13 (All Calls or One Call)

To hide your caller ID on an iPhone 13, open Settings, tap Apps, tap Phone, tap Show My Caller ID, and turn the switch off. Your number is then withheld on outgoing calls, and the person you call usually sees something like “No Caller ID,” “Private,” or “Unknown.” If Show My Caller ID is missing or grayed out, your carrier controls the setting, and you’ll need to use a carrier code or your carrier’s account settings instead.

These steps follow Apple’s iPhone User Guide for iOS 27, which supports iPhone 13, iPhone 13 mini, iPhone 13 Pro, and iPhone 13 Pro Max. The same steps work on other iPhone models with iOS 18 or later. Steps were checked in October 2026.

Hide your caller ID for all calls

Caller ID is the number (and sometimes the name) that appears on the other person’s phone when you call. On iPhone, the Show My Caller ID setting controls whether your number is sent on outgoing calls.

iOS 18 and later (including iOS 27)

1. Open the Settings app.
2. Scroll down and tap Apps. You’ll see an alphabetical list of apps.
3. Tap Phone.
4. Tap Show My Caller ID.
5. Turn off the Show My Caller ID switch. It turns gray.

Your number is hidden on every call you make until you turn the switch back on.

iOS 17 and earlier

In iOS 17 and earlier, Phone is listed directly in Settings. Go to Settings > Phone > Show My Caller ID and turn off the switch.

Check that it worked

Call another phone you own, or ask someone to tell you what they see. Your number shouldn’t appear. The exact label depends on the other person’s phone and carrier.

Hide your number for one call only

If you want to hide your number on a single call and keep caller ID on for everything else, use a per-call blocking code. In the US, Verizon and T-Mobile both document dialing *67 before the number.

1. Open the Phone app and tap Keypad.
2. Type *67, then the full phone number with area code. For example: *67 555 123 4567.
3. Tap the green Call button.

The call goes through with your number hidden. You need to dial *67 again for every call. If you add *67 to a saved contact’s number, that contact will always get a hidden number from you, so it’s usually simpler to dial it on the keypad.

Codes vary by carrier and country, and some carriers may not support them. If *67 doesn’t work, check your carrier’s support site or call customer service.

Unblock for one call. If your number is hidden on all calls, Verizon documents dialing *82 before a number to show your caller ID on that one call. This can help when you call someone who rejects private calls.

Calls that always show your number. Verizon notes that caller ID blocking doesn’t apply to toll-free numbers (such as 800 numbers) or 911. Emergency services can see your number regardless of your settings.

If Show My Caller ID is missing or grayed out

Apple says that if you don’t see Show My Caller ID, your carrier may not let you turn off caller ID from your iPhone. This is common. Some carriers manage caller ID on their network instead of letting the iPhone control it.

Try these options:

• Use a per-call code. *67 may still work when the iPhone setting is missing.
• Use your carrier’s account settings. For example, Verizon lets the account owner or manager turn on Caller ID Blocking for a line in the My Verizon app under Plans & Devices > View details > Block specific services. Other carriers offer similar options in their apps or through customer service.
• Contact your carrier. Ask whether permanent caller ID blocking is available on your plan and whether it costs anything.

A switch that appears but is grayed out usually means the same thing: the carrier controls caller ID for your line.

Caller ID with two lines (Dual SIM)

iPhone 13 models in the US support Dual SIM with a physical SIM card and an eSIM, or two eSIMs. Each line belongs to a carrier, and each carrier decides whether its line can hide caller ID.

What this means in practice:

• Apple’s Dual SIM guide doesn’t describe caller ID settings for each line. Check Settings > Apps > Phone > Show My Caller ID. If your iPhone shows a separate setting for each line, set each one. If one line still shows your number, ask that line’s carrier about caller ID blocking.
• To control which number you call from, choose the line before you call. On the keypad, enter the number, tap the line shown near the top of the screen, and pick your other number. From Favorites, tap the Info button, tap the current number, and choose the other line. Apple documents both methods.
• Per-call codes such as *67 depend on the carrier of the line you’re calling from.

Can you change your caller ID on iPhone?

You can hide your number, but you can’t make your iPhone show a different phone number. The number people see belongs to the line (SIM or eSIM) you call from. To show a different number, call from a different line, such as your second Dual SIM line.

What you can change is how your name appears:

• To your contacts: Apple lists Name and Photo Sharing as one source of caller information. People who turn on Name & Photo Sharing in the Contacts app (My Card > Contact Photo & Poster) can share their name and photo with contacts. Your contacts may also see whatever name they saved for you in their Contacts app.
• To people who don’t know you: The caller name shown on many phones comes from your carrier’s records. Contact your carrier to ask how to update the name on your line. Some carriers offer a feature for this; for example, Verizon lists Share Name ID among its caller ID services.

Turn your caller ID back on

1. Open Settings, tap Apps, then tap Phone.
2. Tap Show My Caller ID.
3. Turn the switch on. It turns green.

If you used your carrier’s account setting to block caller ID, turn it off there too, or dial the carrier’s unblock code for single calls.

Frequently asked questions

What does the other person see when I hide my caller ID?

Usually “No Caller ID,” “Private,” “Unknown,” or “Anonymous.” Verizon says the words “Private,” “Anonymous,” or another indicator appear instead of your number. The exact wording depends on their phone and carrier.

Will people answer if my number is hidden?

Some won’t. Many people ignore unknown callers, and an iPhone set to silence unknown callers (in iOS 26 and later, Settings > Apps > Phone > Screen Unknown Callers > Silence) sends calls from unknown numbers to voicemail. If a call matters, leave your number on or use *82 if your carrier supports it.

Does hiding caller ID hide my number in text messages?

No. Show My Caller ID affects phone calls. Your number or Apple Account still appears on messages you send.

Does hiding caller ID work for FaceTime calls?

No. FaceTime calls show the phone number or email address you use for FaceTime. The Show My Caller ID setting is for cellular phone calls.

Can the person I call still find my number?

Hiding caller ID stops your number from showing on their screen. It doesn’t make you anonymous to your carrier, to emergency services, or to toll-free numbers that receive your number anyway.

Why does my number still show after I turned the setting off?

Your carrier may not honor the setting, or the number you called may be a toll-free or emergency number. Try *67 for one call, or ask your carrier to add caller ID blocking to your line.
