National Car Code

My understanding is that it's a travel agent code- so, you could, possibly, be asked to show your IATA card.

Contract ID 5000304 is for Wal-Mart customers (in other words, anyone) and provides up to 20% off at National.

Contract ID 5504966 appears on the Wal-Mart edition of the Rand-McNally Atlas and provides discounts with National. No proof of purchase needed. Thanks to Joe J for info.
Contract ID 3715444 is reportedly for readers of Car & Driver magazine and provides discounts with National. Thanks to Hot AirBus for info.

Contract ID NCRLESS is sometimes worth a try. This is an ongoing Internet promotion at National and is typically good for rentals within the next couple of months.
