Where to find your phone number on your device

Your phone number is usually stored in your device's settings, though the exact location depends on whether you use an iPhone, Android phone, or another device. The fastest way is to open your Settings app, look for a section labeled "About Phone" or "About Device," and scroll until you see a field for your phone number or "My Number." On some devices it appears when ready; on others you may need to look under "SIM Card Status" or "Network" settings.

If your number does not appear in settings, try opening your phone's dialer app and pressing *#100# (on Android) or checking the SIM card itself — the number is sometimes printed on the card's edge. You can also text yourself from another phone to see what number appears as the sender, or call your own number from a friend's phone and listen for which number they dialed.

Key Takeaways

  • On iPhone, go to Settings > Phone to see your number at the top of the screen.
  • On Android, go to Settings > About Phone > Status or SIM Card Status to find your number.
  • If your number does not appear in settings, check the physical SIM card — the number is printed on the edge.
  • You can verify your number by texting or calling yourself from another phone to see which number appears.

iPhone: Settings > Phone

Open the Settings app on your iPhone and tap "Phone" near the top of the menu. Your phone number appears in large text at the very top of that screen, labeled "My Number." This is the most direct route on any iPhone model.

If you do not see "Phone" in your Settings menu, your device may not have cellular service enabled or may be using Wi-Fi only. In that case, check whether you have an active SIM card inserted — you can see this by going to Settings > General > About and looking for "ICCID" (the SIM card's unique identifier).

Android: Settings > About Phone

Open Settings and scroll down to find "About Phone" or "About Device" (the exact name varies by manufacturer). Tap it, then look for "Status" or "SIM Card Status." Your phone number should appear in a field labeled "My Phone Number," "Phone Number," or "Mobile Number."

On some Android phones made by Samsung, Google, or OnePlus, the number appears under Settings > Network and Internet > SIM Cards. If you have multiple SIM cards, each one will show its own number. If the number still does not appear, your SIM card may not be recognized by the device — try removing and reinserting it, or restart your phone and check again.

Checking your SIM card directly

Your SIM card has your phone number printed on its edge in small text. To find it, power off your phone, locate the SIM card tray (usually on the side of the device), and use the ejector tool that came with your phone or a straightened paperclip to open it. The number is printed along the bottom or side of the card itself.

This method works even if your phone is not turning on or if your number does not appear in settings. Write down the number carefully — the print is small and straightforward to misread. If you cannot read it clearly, take a photo with another device and zoom in.

What to do if your number does not appear anywhere

If your number is not in settings and not printed on your SIM card, your device may not have an active cellular plan. This can happen if you just switched carriers, if your account was suspended, or if you are using a device that was never activated with a phone number.

Contact your mobile carrier directly — you can find their customer service number on your bill, on their website, or by searching "[carrier name] customer service." They can tell you whether your account is active and what number is assigned to your SIM card. Bring your account number or the phone number you think is yours so they can look it up quickly.

Why you might need your phone number

You need your phone number to set up two-factor authentication, to give to doctors or banks, to register for accounts, or to troubleshoot with your carrier. Knowing it also helps you verify that your SIM card is working correctly and that your account is active.

If you use your phone for work or have recently switched devices, write your number down and store it somewhere safe — in a notebook, a password manager, or a note on another device. This way you have it if your phone is lost, stolen, or not working.

Frequently Asked Questions

Why does my phone number not show up in settings?

Your number may not appear if your SIM card is not fully inserted, if your account is not active with your carrier, or if your device does not have cellular service. Try removing and reinserting the SIM card, restarting your phone, or contacting your carrier to confirm your account is active.

Can I find my number if my phone is broken?

Yes. If your phone turns on but the screen is damaged, you can still remove the SIM card and read the number printed on it. If your phone does not turn on at all, contact your carrier with your account information and they can tell you what number is assigned to your SIM card.

What if I have two phone numbers on one device?

If your phone has two SIM card slots (called a dual-SIM phone), each SIM card has its own number. Go to Settings > SIM Cards or Settings > About Phone > SIM Card Status and you should see both numbers listed separately.

Is my phone number the same as my SIM card number?

No. Your phone number is what people call or text you on. Your SIM card has a separate identifier called an ICCID, which is printed on the card's edge. Your phone number is what you need to share; the ICCID is only used by your carrier.
