The fastest way to find your phone number on Android
Open the Settings app on your Android phone. Tap About phone (sometimes labeled About device). Look for a field called Phone number, My phone number, or Mobile number. Your number will be displayed there if your carrier has stored it on the SIM card.
Not all Android phones show this information in the same place, and not all carriers store your number on the SIM card. If you don't see it in Settings, try the other methods below. This is why having a backup method matters — you may need to use one of the alternatives even on a brand-new phone.
Key Takeaways
- Your phone number appears in Settings > About phone on most Android devices, but only if your carrier stored it on your SIM card.
- If Settings doesn't show your number, dial *#62# or *#21# to trigger a forwarding code that displays it on your screen.
- Calling your own number from another phone is the most reliable method if Settings and codes don't work.
- Some carriers hide your number in Settings intentionally, so a forwarding code or test call is often necessary.
- Your carrier's website or app will always display your number, even if your phone's Settings do not.
Using a code to reveal your phone number
Open the Phone app (the one you use to make calls). Tap the keypad icon if it's not already open. Dial *#62# and press the call button. Your phone will display a message showing your phone number and other forwarding information.
If that code doesn't work, try *#21# instead. Both codes trigger your phone to display call forwarding settings, and your number usually appears in the response. The codes work on most carriers, though a few regional carriers may not support them.
These codes don't change anything on your phone — they only request information. You can dial them as many times as you need. The response appears on your screen within a few seconds, and you can screenshot it or write the number down before closing the message.
Calling your own number from another phone
Borrow a phone from a friend or family member and call your Android phone. When you answer, you'll see your own number displayed on the incoming call screen. Write it down before you hang up.
This method works on every carrier and every Android phone, which makes it the most reliable backup if Settings and codes don't work. It's also the fastest way to confirm your number is correct — you're seeing it exactly as other people see it when they call you. If you're worried the number in Settings might be wrong, a test call proves what's actually registered in your carrier's system.
Checking your carrier's website or app
Log into your carrier's website or open their official app. Most carriers display your phone number in the account section or under "My Account" or "Profile". Look for a field labeled Phone number, Mobile number, or Line number.
This method works even if your SIM card doesn't store your number. It's also useful if you want to confirm your number matches what your carrier has on file — sometimes a number gets stored incorrectly during setup. If you're on a family plan, your number will appear under your specific line, separate from other family members' numbers.
Why your phone number might not appear in Settings
Your carrier decides whether to store your phone number on your SIM card. Some carriers do this automatically; others don't. If your number doesn't appear in Settings, it doesn't mean anything is wrong — it just means your carrier chose not to store it there.
Switching phones or carriers can also affect whether your number shows up. If you moved your SIM card from an old phone to a new Android device, the new phone might not recognize the stored number right away. Restarting your phone sometimes fixes this. Turning off airplane mode and waiting a few minutes for your phone to reconnect to the network can also help the SIM card information refresh.
What to do if none of these methods work
Contact your carrier directly. Call their customer service number (usually printed on your bill or on the back of your SIM card) and ask them to confirm your phone number. They can also check whether your number is stored on your SIM card and update it if needed.
If you're setting up a new phone and need your number urgently, your carrier can tell you immediately over the phone. They can also help if you suspect your number was stored incorrectly. Keep your account PIN or password handy when you call — most carriers ask for it before discussing your account details.
Frequently Asked Questions
Why does my phone show a different number in Settings than the one I was given?
Your carrier may have assigned you a different number than the one they told you, or the number in Settings might be outdated. Call your carrier to confirm which number is actually yours. The number they have in their system is the correct one.
Can I find my phone number if I don't have another phone to call?
Yes. Try the *#62# or *#21# codes first. If those don't work, log into your carrier's website or app from a computer or tablet. Your carrier's account page will always show your number, even if your phone doesn't.
Does dialing *#62# or *#21# cost money?
No. These codes are free information requests. They don't use your minutes or data, and they don't change any settings on your phone.
What if I just switched carriers and my old number isn't showing up?
New carriers sometimes take a few hours to fully activate your number on the SIM card. Restart your phone and check Settings again. If it still doesn't appear after a few hours, contact your new carrier to confirm the number was transferred correctly.
Is there a way to find my number without using Settings or calling anyone?
Yes. Log into your carrier's website from a computer or tablet and check your account page. You can also text a friend and ask them to call you back — the incoming call will display your number on their phone.
