Enter your Apple Model ID or A-number — or filter by screen size and year. Some A-numbers cover more than one model, so check the year to pick the exact match.
The A number is printed on the underside of your MacBook’s bottom case. Flip it over and look for “Model A” followed by 4 digits.
Turn your MacBook upside down so the bottom case is facing up.
Look for the small text near the centre of the bottom panel. You’ll see “Model AXXXX” — the 4-digit number after the “A” is your A number.
