Apple Mac Serial Number Lookup
Welcome to MacUpgrades Serial Number Checker, which also lets you search by a Mac's Part Number, Model Number, Model Identifier or EMC Number. You can also search for a macOS version to find all Macs capable of running it.
Please input one of these identifiers below. Some of these can be found written on your Mac, and others can be found by selecting the Apple Menu in the top left, of your Mac's screen, and choosing "About This Mac". For more info about locating your serial number please see here.
Please note that for Mac made from 2021, you cannot search by serial number and will need to use a different identifier - the serial number scheme used by these later Macs does not contain information about which model it is from.
Valid searches are as follows:
- Serial number: this is an 11 or 12 digit alphanumeric code. This tool only works with serial numbers from Mac models introduced in 2020 or earlier.
- Part Number: This is usually a 9 digit code with the last 2 characters being "/A". Older Macs sometimes do not have the last 2 or 4 characters, or occasionally end in "/B". "Build to Order" Macs (those which have certain customisations made at the time of purchase) do not have a Part Number. Example: MYDA2LL/A.
- Model Number: Usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A". Example: A2338
- Model Identifier: In the format MacNameX,Y where the X and Y are numbers. Example: MacBookPro17,1
- EMC Number: Usually a 4 digit code, though in a few cases there are additional characters. Example: 3578
- macOS Version: Finds all Macs that can run this operating system. Either the version number (Example: 10.15 or: 10.13.2) or the name (example: Big Sur).
