How much can a National Discount Code save you?

National Discount Code

What’s a National Discount Code?

National Car Rental assigns Contract ID numbers so that certain customers can get specific discounts. Contract ID numbers can be negotiated for corporate employees (as well as for other National partners) and with regards corporate rates, with National they do tend to be cheaper than public ones. If your organization is affiliated with this car rental company, you may be able to save on your advance rental by adding the relevant ID number to your booking and it can even be stacked with discounts such as coupon codes when booking online.

Airline Credit Cards

Major businesses and discount programs, from American Airlines to MasterCard to Siemens, not only get cheaper rates with a particular National Car Rental discount code, but also sometimes get value-added promotions and special rental benefits. Plus in the travel world, it’s handy to know that you can earn miles or points by attaching your Frequent Travel Program number to a new or existing National reservation.

A Contract ID is usually a numerical code, though there are odd alphabetical exceptions. There doesn’t seem to be a comprehensive list of codes online, so we scoured the internet to find as many as possible, to see how much you can save.

As expected, you can only generally use a Contract ID number if you have ID to prove that you’re entitled to the rate when picking up your rental, or you could be charged the full daily rate.
