How to check apple adapter is original or fake

Hi Sanju3091,

Welcome to Apple Support Communities.

We understand you're looking for clarity on counterfeit Apple products and you were able to review Find the serial number of your Apple product. If you're looking for the serial number on a power adapter or cable, they would not have a serial number etched on them.

You can view a few keywords that you should see as mentioned in Identify counterfeit or uncertified Lightning connector accessories.

Regards.
