Where to find your phone number on iPhone

Your phone number is stored in your iPhone's settings, not in the phone app or contacts. Open Settings, tap Phone, and look at the top of that screen — your number appears next to "My Number". This is the fastest way to see it.

If you do not see a number there, your SIM card may not be registered with your carrier yet, or you may be using an eSIM that has not activated. In either case, contact your carrier directly — they can confirm what number is assigned to your account.

Key Takeaways

  • Your phone number lives in Settings > Phone > My Number, not anywhere in the Phone app itself.
  • If no number appears there, your SIM or eSIM has not finished activating with your carrier.
  • Your carrier's customer service line (usually printed on your bill or SIM card packaging) can tell you your number if Settings does not show it.
  • On a new iPhone, wait 24 hours after inserting a physical SIM or activating an eSIM before checking — set up takes time.

Why the number does not always show up

A blank "My Number" field usually means one of two things: your SIM card is new and still activating, or your eSIM has not completed its setup. Both are normal. Physical SIM cards can take up to 24 hours to register with your carrier's network, and eSIMs sometimes need a restart of your phone to finish activating.

If you have had the SIM in your phone for more than a day and still see nothing, restart your iPhone by powering it off and back on. If that does not work, your carrier may need to push the set up to your phone manually — call them and have your account number ready.

Another reason your number might not display is if you are using a dual SIM setup (both a physical SIM and an eSIM at the same time). In this case, Settings > Phone > My Number shows only your primary line. To see your secondary number, you will need to contact your carrier or check your carrier's app, where both numbers are usually listed under account details.

Getting your number from your carrier if Settings is blank

The fastest way is to call your carrier's customer service line. You will find this number on your bill, on your carrier's website, or on the SIM card packaging. Have your account number or the phone number associated with your account ready when you call.

You can also text a carrier-specific code to get your number back. AT&T customers can text "INFO" to 611611. Verizon customers can dial *611 from any phone. T-Mobile customers can dial 611 from their phone. These shortcuts connect you to automated systems that will text or read your number back to you.

If you prefer not to call, log into your carrier's website or mobile app using your account credentials. Most carriers display your phone number prominently on the account dashboard or in a section labeled "My Account" or "Account Details". This method works even if your iPhone has not activated yet.

Checking your number on a phone you just switched to

When you move to a new iPhone, your number transfers with your SIM card or eSIM, but it may not show in Settings when ready. Wait at least an hour after the transfer completes, then check Settings > Phone > My Number again. If it still does not appear, restart the phone.

If you transferred your service using eSIM during setup (the process that lets you scan a QR code instead of using a physical card), the number may take longer to appear — sometimes up to 24 hours. This is normal. Your phone is working correctly even if Settings shows nothing yet.

During the waiting period, your phone can still make and receive calls even if Settings has not updated. The delay is purely a display issue. If you need to confirm your number is active before Settings updates, try making a test call to a friend or checking your voicemail — both will work if your number is live on the network.

What to do if you need your number urgently

Do not wait for Settings to update. Call your carrier's customer service line directly — they can tell you your number in seconds. Keep your account number handy, which you can find on your bill or in your carrier's app.

If you cannot reach your carrier by phone, use their website or mobile app to log into your account. Most carriers display your phone number on the account dashboard or in the "My Account" section. This works even if your iPhone has not activated yet.

Frequently Asked Questions

Why does my iPhone say "My Number" but show nothing next to it?

Your SIM or eSIM has not finished activating. Wait 24 hours and restart your phone. If it still shows nothing after that, contact your carrier — they may need to manually push the set up to your device.

Can I see my phone number in the Phone app?

No. The Phone app shows your contacts and call history, but not your own number. Settings > Phone > My Number is the only place in iOS where your number appears.

I switched carriers but my old number still shows in Settings. What happened?

Your phone has not connected to the new carrier's network yet. Restart your iPhone and wait a few minutes. If the old number persists after a restart, turn airplane mode on for 10 seconds, then off again. If it still does not update, contact your new carrier.

Does my phone number change if I get a new iPhone?

No. Your number stays the same as long as you keep the same SIM card or eSIM. When you move to a new iPhone, transfer your SIM or eSIM to the new phone, and your number comes with it.

What if I have two phone numbers on one iPhone?

If you use dual SIM (a physical SIM and an eSIM together), Settings > Phone > My Number shows only your primary line. To see your secondary number, open your carrier's app or log into your account online. Both numbers are active and working even though only one displays in Settings.
