The social security number is listed in the official requirements for getting the card posted by the Celtic Bank. If you try to apply for this card, in particular, you will see that the social security number field in the application form is required. There are two reasons for this. - First, federal law requires the bank to obtain, verify, and record information that identifies its customers. (See: Identity Security Tips) - And, second, the bank needs your social security number to pull your data from a credit bureau and get hold of information about your monthly income. You can check Deserve EDU Mastercard or Jasper Mastercard. These cards do not require SSN to apply*.
