Hello,

Identification marks as the name suggests are the marks present in a person's body through which he can be identified and distinguished from another individual.

Identification marks includes marks such as birthmarks, moles and scars. Identification marks vary from person to person and of an individual and can be used for identification.

Kindly look for any black mole or scar present on your body specifically on your face and that will serve the purpose for you.

Almost Everyone has moles on their bodies, so you can enter those. That would be sufficient.

I hope you find the answer helpful.

Thank you
