Generally when you apply for a credit card, you will receive an acknowledgement either by SMS or email or both in which you will receive the details of your application number and the reference number. This reference number is important and can be used to track the status of your application.
To check the status of your application you have to visit the bank site ( www.hsbc.co.in ) and then go to the credit card section. There you will have to input your application number, reference number, mobile number or date of birth etc to validate your authenticity. After this you will be taken to the status page of your application where you can find up to what stage the application is processed or pending for want of some document from your side. Anyway, in such cases you will get message to submit the document if any.
Sometimes to validate your mobile number they will send a OTP in it which you have to enter and verify that it is your number.
