Even when the number is localized by the first numbers, the number is not based on birth locals, it is based on 'issued' locals. People can receive their ssn at any age and any location. Plus, don't forget, validating against a pattern of 3-2-4 won't account for TINs with a pattern of 2-7.

They wouldn't necessarily mean the number was an actual valid SSN that is actually in use somewhere... just closer to being one. - None of the sections can be all 0's - There are some reserved numbers but I don't recall what they are. Think they may start with 999 or something. Im sure google knows. - I've heard that 666 cannot be in an SSN. Ive never seen one with it but don't know that it's actually true A basic check would consist of: <cfset SSNNUMBER = "555-55-5555" /> <cfset strippedSSN = rereplace(ssnNumber, '[^0-9]', '', 'all') /> - Make sure the stripped ssn is 9 numbers <cfset isNineNums = len(strippedSSN) is 9 /> - Make sure that none of the 3 sections is 0 <cfset ssnArea = left(strippedSSN, 3) /> <cfset ssnGroup = mid(strippedSSN, 4, 2) /> <cfset ssnSerial = right(strippedSSN, 4) /> <cfset invalidZeros = val(ssnArea) is 0 or val(ssnGroup) is 0 or val(ssnSerial) is 0 /> - And if you believe the 666 tale... <cfset isBeastySSN = find(666, ssnnumber) /> - Check them all for a final result <cfset validSSN = not invalidZeros and isNineNums and not isBeastySSN /> <cfdump var="#variables#" /> Other than finding the reserved numbers and filtering those, I think that is the best you can do for now. ....:.:.:.:.:.:.:.:.:.:.:.:.

For example, the current validation used for cfinput would return 111-11-1111 as a valid ssn. I guess it could be valid, but I don't think it is. I need something that would verify if this is an ACTUAL ssn. Kind of like we do for credit cards. Any ideas? Thanks!
