Canadian passport number, two upper case letters followed by six digits, per the Purview Canada passport definition. No checksum. Reproduced collisions: this is the same shape as BR_PASSPORT and as the eight character form of ES_PASSPORT, so all three fire on the same value; and the six digit tail is separately matched by IN_PIN. Only the surrounding words tell a Canadian booklet from a Brazilian one.
