508[5-9]\d\d\d\d\d\d\d\d\d\d\d\d
607[0-8]\d\d\d\d\d\d\d\d\d\d\d\d
6079[0-8]\d\d\d\d\d\d\d\d\d\d\d

Rupay credit cards have been recently introduced and the DI does not include the pattern for the credit cards yet

Resolution

Additional Information

Temporary workaround is to use a custom DI and add the below pattern to the existing range of patterns
