That's why, when somebody asks you for your SSN, you can "accidentally"
transpose a couple of digits and they can't check.

There are, however, constraints on the three fields - a SSN of 999-xx-xxxx
can be detected as false.



Hi,

I wrote a COBOL program that uses a check-digit to verify SSN,
it utilizes the modulus 11 method described below. By the way,
method used here refer to a procedure or a technique and not
as used in OOP terminolog.
