U.S. / U.K. Passport Number

live testingcurated2 patternsproximity 300recommended confidence 75 (medium)

A nine-digit number, validated as a passport only by nearby passport keywords.

A passport number is just nine digits, the same as an unformatted SSN. Only the nearby keywords decide which SIT fires. One document containing "passport number 123456789" near "SSN" can light up both SITs at once, which is why DLP alerts sometimes report two detections for one value.
