How to identify iMac models

By serial number

On most computers with Mac OS X, you can find the serial number in the About This Mac window. Otherwise, see iMac: How to locate the serial number to learn where to find the serial number on the surface of your iMac.

Type the serial number into the Check Your Service and Support Coverage page. The resulting screen will show your model.

By marketing number on the box

You'll find a sticker on the outside of the original iMac packaging that lists the part number. Just match your number with one in the table below to find your iMac model. The two characters before the slash (/) vary by country, but the rest of the part number will be the same worldwide ("XX" represents the two variable characters below).
