Agencies often as a vendor during sales calls if they have a GSA number which refers to the number GSA assigns to your contract. When asked this question, the Federal agency is merely asking if you have a GSA Schedule contract and, if so, what the contract number is.
GSA contract numbers used to follow this format: GS-XXX-XXXXX. The first two digits stand for General Schedule. The next three digits refered to the specific schedule you have been awarded a contract under a specific GSA schedule. For example, an IT scheduled 70 happens to use the code 35F. The final numbers (including a letter) are specific to your company.
Since 2018, new contracts have contained long strings of letters and numbers that do not include the items described above.
If you can tell an agency buyer your GSA number, then they will smile, because they know they can work with you pretty easily.
If you tell them you do not have a GSA contract, then the agency buyer usually sighs and shrinks into their seat. That's because while they like what you can offer them, they know that contracting with you will be more difficult.
