AR_Shorty:
SS card should not be necessary. My local Sherrif Deputy (Allegheny County) stated that only ID that showed you current address was accepted. Seemed they wanted PA state issued ID's (drivers license) and something like a vehicle registration. SS card has no address on it; nor does a passport. Neither were accepted when I renewed my CCW permit about a month ago.
When I renewed my pemit I checked all boxes for "reasons" (hunting, self defense, job, etc.). They put protection on my permit. There isn't room for anything else in the box. My old paper permit said hunting and protection.
Just make sure that you have your Drivers license, vehicle registration or some other form of ID that has your name and address on it, two references with full address (one guy left off the zip for one of his references and the deputy made him get it) and the 19.00 cash.
