Model No. (e.g., A1321, A1286)

Click the Apple logo in the top‑left corner → About This Mac
You will see the model and year (e.g., MacBook Air 13‑inch, 2020)
Click More Info → System Report
Under Hardware Overview, look for Model Identifier: Axxxx
Method 3:
Use the serial number on the official Apple website:
Go to About This Mac → copy the Serial Number
Open the Apple website → Serial Number lookup
ial number → search → you will receive the full model information and A‑number
