I know there have been a lot of discussion related to this topic, e.g. Credit Card validation: can Card Name contain non-ASCII characters?
The reason I wanted to ask this question is because people could find all the information at one place.
What I've found out (Please correct me if/where I'm wrong):
Title - Length - Format
Credit Card Number - MIN 13, MAX 19 - Numeric
Credit Card Name - MAX 26 - Alpha Numeric (Cannot contain dots after Initials?)
Bank Account Number (btw, I'm in India) - MIN 11, MAX 15 - Numeric
Bank Account Name - Sorry, no idea - Alpha Numeric? (again, no idea)
Please provide answers so that this will help people who have to juggle with financial data.
