We have a customer that opened a checking account and we have discovered that the ss number was issued before date of birth. Tried calling SS but not getting any response. Any suggestions.

Did you see the SS card or was the number given verbally? That would influence my decision. If I have an image of the SS card and can verify we didn't transpose a number, I would close out the account and mail the person a check for the balance. If it is possible I transposed the number and couldn't get SS to help, I would require the customer to bring in the card to verify and decide what to do at that time.

How do you know it was issued before the date of birth? Those services providers may not be accurate.

I agree with rlcarey. At a previous employer we used LexisNexis to verify a customer's identity (Name, DOB, Address, SSN). Information as to SS # origin location and issue date was very commonly inaccurate. We did not use that information to make any decisions.
