Damaged Indian passport. To apply for a new passport what should be done?
It doesn't make much difference if the name, photo and passport number are still readable - see the following from the Embassy of India:
Damaged passport is classified further based on the extent of damage, i.e.:
- Damaged Passport - Passport number is readable, name is legible and photo is intact
- Damaged beyond recognition
To apply for duplicate passport in case of lost or damaged passport, you need to apply for "Re-issue" of passport.
To apply for a re-issue of a passport, like you'll need to - you follow the same steps as any person getting a new passport. PassportIndia.gov.in has the application page with instructions - note that:
If you ever held a passport in the past, no matter how much long back or at what age, you should choose the Re-Issue category only.
