Dear All,
Nowadays, banks ask for certain documents as proof of address:
1. PAN Card forwarding letter
2. Passport
3. Voter's ID card
4. Driving Licence
5. Telephone Bill
6. Electricity Bill
The employer can request any of the above documents from the employee, which should be self-attested by the employee. Based on such documents, the employer can issue a certificate enclosing the self-attested documents received from the employee. This practice will help the employer remain in a safe zone in the event of any problems.
