It’s also worth mentioning that as of Oct. 1, 2015, GM announced a change to its Supplier Employee Program. The authorization code for this discount changed from GSU to GSP. All authorization codes issued under the old GSU code name will be honored through the expiration date and will not require proof of eligibility. However, under the new GSP program code, employees of supplier companies will be required to show proof of eligibility by providing a copy of a Company ID badge or a current paystub.

The GM Supplier Discount Program is compatible with most other incentives and rebates and is good for a purchase or lease of a new Chevrolet. Each time you purchase or lease a new GM vehicle under the GSP program, you can share your supplier discount with one friend or family member up to one year of your vehicle purchase. Once you obtain an authorization number for your prospect, they have six months to use it. This discount for friends is coded GSF and does not require proof of eligibility.
