You must have your DUNS Number and know your Contract number when you access the system.

4. Schedule Specific Mod Requirements

In eMod, you will find required attachments for each modification. However, these are GSA generic requirements and each schedule may have additional required attachments for each mod type. Please check the latest GSA modification guidance package for the specific schedule you are doing modification against to ensure you have all the required attachments for the modification you are completing.
