To find your phone number on an iPhone 7, open Settings, tap Phone, and look at My Number at the top of the screen. You can also open the Contacts app (or Phone > Contacts) and tap My Card at the top of the list. Your number is listed there if it’s saved to your contact card.
These steps also work on newer iPhones. On iOS 18 and later, go to Settings > Apps > Phone. Below you’ll find every place to look, and what to do if My Number is blank or wrong.
Method 1: Check Settings
- Open the Settings app.
- Scroll down and tap Phone.
- Your number appears next to My Number.
If you use two lines (a physical SIM and an eSIM), go to Settings > Cellular (or Mobile Data) to see each line and its number. The iPhone 7 supports one SIM, so you’ll only see one.
Method 2: Look at your contact card
- Open the Contacts app, or open Phone and tap Contacts.
- Tap My Card with your name at the top.
- Your phone number is listed if it’s saved on the card.
If your card is missing or outdated, edit it and add your number. That also helps when you share your contact info with AirDrop.
Method 3: Check Messages or FaceTime settings
Go to Settings > Messages > Send & Receive, or Settings > FaceTime. Your phone number is listed under the addresses you can be reached at, as long as iMessage or FaceTime is turned on.
Other ways to find your number
- Call or text a friend and ask them what number shows up.
- Check your carrier’s app or account website, or your monthly bill.
- Look at the SIM card packaging if you still have it.
Why is My Number blank or wrong?
- New SIM or number change: My Number is pulled from your SIM card. Restart your iPhone after changing SIMs.
- Carrier issue: Some carriers don’t write the number to the SIM. Check for a carrier settings update in Settings > General > About (a prompt appears if one is available).
- Ported number: After moving your number to a new carrier, the old number can linger for a while. Contact your carrier if it doesn’t update.
- Edit it yourself: On some carriers, you can tap My Number and correct it. This only changes what’s shown on your iPhone, not your actual number.
If you have two lines, the line picker at the top of the keypad, covered in how to dial a phone number on iPhone, shows which number each call will come from.
Frequently asked questions
Can I find my number without a SIM card?
Not on the iPhone itself. Check your carrier account, a bill, or the SIM packaging.
Why does iMessage show my email instead of my number?
Go to Settings > Messages > Send & Receive and choose your phone number under Start New Conversations From.
Is there a code to dial to see my number?
Some carriers offer one, but codes vary by carrier and country. Settings > Phone is the most reliable method.
