GSA Global Supply Points of Contact

One of the goals of this Interact community is to foster greater understanding of the GSA Global Supply program among our vendor partners.  The notes below outline some resources we trust will be helpful to you in the event that you have questions or concerns. We’ll start with some basic points of contact and then highlight a few more specific options. Keep in mind that you can always ask a question by replying to any of the posts on this site. We’ll talk to the relevant subject matter expert and then share our answer with the entire community.


GSA National Customer Service Center (NCSC): Call (800) 488-3111 or email NCSCcustomer.service@gsa.gov from 9:00 p.m. Sunday to 9:30 p.m. Friday. They handle customer inquiries or discrepancies on individual orders and can help you with data on specific orders.
