How to find your phone number on iPhone and Android (even if it shows Unknown)

It is more common than you would think to forget your own number, especially after switching carriers or getting a second line. The number is stored on your SIM or eSIM, and your phone can show it in a few taps. This guide lists the quickest methods for each phone, shows what to do if it says Unknown or is blank and covers ways to find a number when you do not have the phone in hand.

How to find your number on an iPhone

• Contacts app: open Contacts and tap your name at the top, or go to Settings › Contacts › My Info and choose your card.
• Messages: open Settings › Messages › Send & Receive, and see the numbers and emails that iMessage uses.
• FaceTime: open Settings › FaceTime and see Your number at the top.

Other ways to find your number

• Call or text a friend. Their phone shows your number. Ask them to read it back, and save it.
• Your carrier app or website. Verizon, AT&T, T-Mobile and others list your number on the home page or account page.
• Your bill or an email from your carrier. Each line is listed with its number.
• The SIM packaging or the welcome text. New SIMs often come with a card that shows the number.
• Dial a carrier code. Some carriers let you dial a short code, such as 611, to reach customer service, who can tell you your number after you verify your account.

Your number shows Unknown or is blank

What if you have two numbers?

Dual SIM phones, and phones with an eSIM and a physical SIM, show a separate number for each line. iPhones label them Primary and Secondary, or by names you set, and Androids show SIM 1 and SIM 2. Each can have its own number, carrier and plan. Check which line is used for calls, texts and mobile data in your SIM settings. If you are not sure which number belongs to which line, call a friend using each line, or look at your carrier accounts.

Why you might need your number

• Signing up for services and verification codes.
• Switching carriers and moving the number.

Moving your number needs a PIN, see how to get a number transfer PIN. If you want to confirm the network, read how to find out which carrier your phone uses. You might also need to set up voicemail, see how to set up voicemail on an iPhone.

Keep your number safe

• Do not post your number publicly, which invites spam calls and scam texts.
• Add a PIN and a number lock to your carrier account.
• Be careful about who you give it to, and what accounts depend on it.

Find your number with your carrier

Your carrier always knows your number. Open its app or website and sign in: My Verizon, myAT&T or T-Life (T-Mobile) all show the numbers on your account on the home screen. Your monthly bill lists every line too, by number. If you cannot sign in, call support from the phone and they can confirm the number after checking your identity.

Numbers on an eSIM

With an eSIM, there is no card to look at, but the number works the same way. On iPhone, Settings › Cellular lists each line with a label like Primary or Business. Tap a line to see its number. On Samsung, look in Settings › Connections › SIM manager. On Pixel, go to Settings › Network & internet › SIMs.

iPads, tablets and smartwatches

A cellular iPad or tablet has its own data number, even though it cannot make normal calls. Find it in Settings › General › About under Cellular Data Number. A cellular Apple Watch or Galaxy Watch usually shares your phone's number through a feature like NumberShare, but has its own hidden number on the carrier's side. The carrier app shows it if you ever need it.

Google Voice and second numbers

If you use Google Voice, open the app and tap the menu. Your Voice number is shown at the top. Apps like TextNow or a work calling app have their own numbers in their settings. These are separate from your carrier number, and people who text your carrier number will not reach those apps.

Phone will not turn on?

Look at your carrier bill or app on another device. You can also take the SIM card out and check the card holder or the packaging it came in, which sometimes has the number printed. Some older contact backups list your own number under My Card. If the phone is lost, your carrier can confirm the number and suspend the line.

Do not share your number carelessly

Your phone number is often used to reset passwords, so treat it like personal information. Do not post it publicly, be careful with giveaway forms, and ask your carrier to add a port out PIN or number lock so nobody can move your number to another carrier without permission.

Save your own number in Contacts

Once you know your number, save it so you never have to search again. On iPhone, your own card sits at the top of Contacts as My Card; tap it, tap Edit and add the number. On Android, open Contacts and look for your profile at the top, often called Me or My profile. You can then share your contact card with one tap when someone asks for your number.

Ported your number recently?

After moving to a new carrier, your phone may show the number as Unknown for a day while activation finishes. Restart the phone once the transfer completes. If it still shows nothing, the carrier can resend the settings.
