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.

You may need a serial number and product key to activate someAutodesk software.

Note: If you are on subscription, you may no longer need toenter a serial number or product key; you just need to signin. Serial numbers are never required for launching productswith network licenses.

Serial Number Locations

Serial numbers are unique codes associated with your AutodeskAccount and a particular product that you have purchased or isotherwise available to you. For 2014 versions and later, you canfind them in Autodesk Account, on the Management tab. Depending onyour license type, you may not need a serial number to launch yourproduct.

Autodesk Account

The Management tab of your Autodesk Account page stores theserial numbers and product keys for each licensed product.

Note about serial number visibility in AutodeskAccount: Only account administrators, such as ContractManagers and Software Coordinators, and Named Users with assignedsoftware benefits will see serial numbers in Autodesk Account.You are the account administrator if you purchased a softwaresubscription using your Autodesk Account or were assigned the roleof Contract Manager or Software Coordinator by your company. If youdo not see the software you wish to activate in your Autodeskaccount or see the message 'Contact your admin for serial numbers,'you need to contact the account administrator. Only anadministrator can assign you as a Named User or End User and giveyou permissions to download and activate the software.

Physical Media

Serial Numbers do not appear on software packaging forAutodesk software versions 2014 and newer. Serial numbers for theseversions are emailed to you after you place an order or can befound in AutodeskAccount.

If you have physical media (a DVD or USB key) for a 2013or earlier product, your serial number and productkey will be printed on the label of the productpackaging.

Example of label from 2011 version. Format is similar for 2010- 2013 product releases.

Product Key Locations

Product keys are codes that identify each productversion.

• You can find product keys for recent versions of your productin Autodesk Account, on the Management tab.

• To look up a product key for a particular product version (2010and later), you can also go to: Look UpProduct Keys.

Older product keys

If you can't find the product key for older versions ofAutodesk software (2013 and later), you may be able to findit in a text file in the installation folder.

To determine if your product key is available inyour installation folder:

1. Using your installation media, (USB key, DVD, download folder,etc.) navigate to the folder that contains the setup.exefile for your Autodesk product.
2. In that folder, look for a file named MID.txt,MID01.txt, MID02.txt or some variation on thatname.
3. Open this file in Notepad and verify that the product name iscorrect.
4. The first five characters of the part number should also be theproduct key for that product.
