At some point in time, you may need to know your iPhone’s serial number and SIM number. And if you don’t have your own phone number memorized, well, it goes without saying that you’ll need to look that up, too. Here’s where to find these three numbers on your iPhone.
Find your phone number
I know, I know, you probably know your cell number by heart, but if you’re anything like me, it may take months for you to memorize your number, especially if you recently changed it.
iOS gives you a couple different ways to find your phone number. One method is to go to Settings > Phone and then look for “My number.” This will give you your country code, area code, and number. Alternately, you can go to the Phone app, tap Contacts, then scroll all the way to the top. Tap your name and number, and you can edit your own contact card.
Find your serial number
To locate your phone’s serial number, go to the Settings app, tap General, then tap About to view various details about your phone. Scroll down and look for the “Serial Number” entry, and make a note of the alphanumeric string that follows.
Find your SIM card number
Each SIM card has a unique identifier known as an “integrated circuit card identifier,” or ICCID for short. To find this number, head back over to Settings > General > About, scroll down, and look for the ICCID. An ICCID can be quite long, so you’ll want to check and double-check it if you write it down.
Settings > General > About also provides a number of other details about your phone, such as your phone’s model number, its IMEI (another unique identifier that applies to the phone itself), and which version of iOS you’re currently running.
