GSA Advantage!® New Log in Functionality

Use of Personal Identity Verification (PIV) or Common Access Card (CAC) is LIVE and available for the following GSA Applications:

  • GSA Advantage! & Virtual Stores (e.g., Air Force Advantage)
  • GSA Global Supply (GGS)
  • USMC ServMart
  • eBuy (Buyer)

This added feature simplifies the login process for customers who rely on GSA systems and services to accomplish their agencies' missions.

What actions do I need to take to register and use my PIV/CAC card for these systems?

To benefit from this new feature on any of these websites, you'll first need to register a working PIV/CAC card with your existing GSA Advantage account. To do that, follow these steps:

  1. Login to GSA Advantage!
  2. Navigate to "My Account"
  3. Click on the "Member Information" page
  4. Select the new "Register PIV/CAC card" button

For more detailed guidance on enabling this feature, go to the PIV/CAC Registration Instructions Page on GSA Advantage.

These steps must be completed on GSA Advantage before you attempt to login with your PIV/CAC. Once your card is registered on GSA Advantage, you'll be able to login to any of the four sites using just your PIV/CAC card and associated PIN on the system’s logon page using the newly added PIV/CAC card sign in button (shown below).
