How to Find Your Own Mobile Number

It happens to everyone: someone asks for your number and your mind goes blank, or you've just put in a new SIM and have no idea what number came with it. Here are the quickest ways to find it.

On an iPhone

• Open Settings, then Phone. Your number is shown as My Number at the top.
• Or open the Contacts app and tap your own card (My Card) at the top of the list.

On an Android phone

• Open Settings, then About phone. Look under Phone number or SIM status.
• On some phones it's under Settings, Connections or Network, then SIM card manager.
• Your own contact card in the Contacts app may also show it.

If the number shows as "unknown", the SIM may not have it stored. Try one of the methods below.

Call or text someone

The simplest method: ring a friend or family member and ask them to read out the number that appears. Make sure your caller ID isn't set to withheld first.

Use your network's short code or app

Most UK networks have a free short code or text service that tells you your number, and all of them show it in their app and online account. Codes change from time to time, so check your network's help pages for the current one rather than relying on an old list.

Check the paperwork

• A new SIM often comes in a card that shows the number.
• Your monthly bill or contract confirmation will show it.
• Your online account with your network will always list it.

Dual SIM and eSIM phones

If your phone has two lines, each will have its own number. In settings, look for the SIM or mobile plan section, where each line is listed separately with its number.

Save it somewhere safe

Once you've found it, add it to your own contact card and write it down somewhere off the phone. You'll need it if your phone is ever lost or stolen.

Got a call from a number you don't recognise?

That's the other half of the puzzle. Type it into Who Called Me Check to see what kind of number it is and what other people have reported about it.
