Add-on process:
- Add-on applicant address proof must be in bank serviceable location.
- Raise a request by providing primary card number and mobile in online to get callback.
- Immediately Citi people will call and schedule for document pickup.
- Required documents: PAN, Address Proof, Add-on application form.
- Two passport size photos 🙁
So, it's basically like applying new credit card in Offline method but we're applying here Add-on.
