Is MacBook air M1 model number Z124J006KD is guanine ? I see it starts with MG* in Apple website.

It’s official e commerce portal like Amazon.com in india called Flipkart.com where I bought MacBook Air 2020 model which has part number starts with Z* series.

I crossed checked in a physical apple reseller store ( as no apple physical stores in India ) an employee there told , 16GB is customised models so it carries z* series.

I will receive in a couple of days , I hope I can check from an apple website it’s authenticity like we check iPhone IMEI number .

Well, One of the apple authorized resellers in India told me , customized models with 16GB has Z* series.

So, may I know if you answer is official from apple , then I should be worried about my purchase.

genuine ( it was a typo, sorry)

I already checked this webpage, it was last Published Date: November 30, 2020 and i came to know in 2021 manufactured models or customized models with 16GM RAM may contain such series, wanted to confirm that .
