rsingh, Could you please upload screenshots/logs of the SSNs matching and not matching? Also please verify your dynamic update versions here also. Easiest way would be to do a 'show system info' output from command line, or screenshot the info from Dynamic updates in the WebGUI. I specifically took a look at some of the SSNs you mentioned to see if they should, or should not, match according to the SSN patterns listed on the .gov websites. SSNs are broken down into three sections. EX: 111-22-3333 Area Number (111) Group Number (22) Serial Number (3333) Area Numbers can range from 001-772 Group Numbers can range from 10-99 Serial Numbers can range from 0001-9999 Using the above information, we can determine what should, and should not, be allowed by the pattern specified for SSNs. 111-11-1111 matches the criteria listed. 888-88-8888 does not match the criteria listed. The 888 Area number is not valid. 458-00-5689 does not match the criteria listed. The 00 Group number is not valid. 458-98-0000 does not match the criteria listed. The 0000 Serial number is not valid. 078-05-1120 does not match the criteria listed. The 05 Group number is not valid. 219-09-9999 does not match the criteria listed. The 09 Group number is not valid. 123-45-6789 does meet the criteria listed. I'm not sure exactly what the signature pattern is, but it looks like they need to include the exceptions you mentioned, such as 111-11-1111, 888-88-8888 and 123-45-6789. 219-09-9999 should not meet the criteria per the group number, yet ssn validator says the ssn is valid?

This is prone to false positive' I am looking into the pattern match information to confirm.
