Where to find your phone number in Settings

Your iPhone stores your phone number in the Settings app. Open Settings, tap Phone, and look at the top of the screen — your number appears next to "My Number". This is the fastest way to check what number your carrier assigned to your device.

If you don't see a number listed, or if it shows as unknown, your SIM card may not have activated yet or your carrier hasn't provisioned the number. Contact your carrier's customer service to confirm your number is active on the account.

Key Takeaways

  • Your phone number appears in Settings > Phone > My Number at the top of the screen.
  • If no number shows, your SIM card may not be activated or your carrier hasn't assigned the number yet.
  • You can also find your number by dialing *#62# or checking your carrier's app or website.
  • A missing number usually means contacting your carrier is the next step, not a problem with your iPhone.

Using the Phone app to see your number

Open the Phone app and tap Contacts at the bottom. Scroll to the very top of your contacts list — your own number should appear in a card labeled "My Card" or simply showing your name. Tap it to see your full phone number displayed.

This method works on most iPhones, though the exact location can vary slightly depending on your iOS version. If you don't see your card at the top of Contacts, you may need to create one first by tapping the plus icon and entering your own information.

Checking your carrier's app or website

Your wireless carrier — whether Verizon, AT&T, T-Mobile, or another provider — displays your phone number in their official app or on their website. Log into your account through the carrier's app or website, navigate to your account details or phone line information, and your number will be listed there.

This method is especially useful if you have multiple phone lines or recently switched carriers, because the carrier's system is the source of truth for what number is actually active on your account. It also shows you exactly what the carrier has on file, which can help if you're troubleshooting a problem.

Using the *#62# code to retrieve your number

Open the Phone app and dial *#62#, then press the call button. Your iPhone will display a popup showing your phone number and other call-forwarding information. This method works on most carriers and doesn't place an actual call — it simply queries your SIM card for the information.

If the popup doesn't appear or shows an error, your carrier may not support this code, or your SIM card may not be fully activated. In that case, the Settings app or your carrier's website are more reliable options.

What to do if your number doesn't appear

If Settings, the Phone app, and your carrier's website all show no number or "unknown", your SIM card likely hasn't been activated yet. This happens most often with new phones, new SIM cards, or after switching carriers. Contact your carrier's customer service — they can confirm whether the number has been assigned and activate it if needed.

If you recently switched to a new iPhone but kept the same SIM card, the number should transfer automatically. If it doesn't show up within a few hours, restart your iPhone by turning it off and back on. If the number still doesn't appear after a restart, your carrier can troubleshoot whether the SIM card itself is the problem.

Finding your number on a family plan or shared account

If your iPhone is part of a family plan or a business account with multiple lines, each phone has its own number. The Settings > Phone > My Number path shows only the number assigned to that specific device. If you're unsure which number belongs to which phone, log into your carrier's account online or call customer service — they can list all phone numbers on the account and tell you which one is tied to your iPhone.

Family members or employees on the same plan can each check their own iPhone using the same Settings path, and each will see their own assigned number. This is useful if you need to give someone else their number or if you're managing multiple devices.

Frequently Asked Questions

Why does my iPhone show "unknown" instead of my phone number?

Your SIM card hasn't been activated yet, or your carrier hasn't provisioned the number to your account. Restart your iPhone first — wait 30 seconds and turn it back on. If it still shows unknown, contact your carrier to confirm the number is active.

Can I find my number if I don't have a SIM card?

No. Your phone number is stored on your SIM card and in your carrier's system. Without a SIM card, your iPhone has no number to display. Insert an active SIM card, wait a few minutes for it to register, and the number will appear in Settings.

Does my number change if I get a new iPhone?

Not if you move your existing SIM card to the new phone. Your number stays the same because it's tied to the SIM card, not the device. If you get a new SIM card, your carrier may assign a new number unless you specifically request to keep your old one.

What if I see multiple numbers in Settings?

You likely have an eSIM (digital SIM) and a physical SIM card both active on your iPhone. Settings will show both numbers. If you only want one active, go to Settings > Cellular and toggle off the line you don't need.

Is there a way to hide my phone number from others?

You can block your number from showing up on outgoing calls by going to Settings > Phone > Show My Caller ID and toggling it off. This hides your number from people you call, though some carriers may override this for emergency calls.
