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.
One way to check if your card is active is by calling your card issuer's customer support phone number and asking. This number is usually listed on the back of your card. Besides maybe a few seconds of hold time, this is the quickest and easiest way to check the status of your card.
Closed Accounts and the Credit Reporting Time Limit Even though the credit card account is closed, it will remain on your credit report at least for the duration of the credit reporting time limit. If you're still making payments on the balance, the payment history and timeliness of your payments will also be reported.
