About the data

Source

Everything here comes from the OASIS+ contract holder list that GSA publishes as a spreadsheet, about once a month. Each update replaces the data with the newest file, so the site is as current as the "Updated" date shown on every page, not real time.

This site is run by outcome/one. It is not affiliated with or endorsed by GSA.

Vendors, contracts, and pools

Vendor

A company, identified by its Unique Entity ID (UEI). A vendor's name and address are taken from its most recently changed active contract; where a contract lists a different name or address, the vendor page shows it under that contract.

Contract

One OASIS+ contract. A vendor holds at most one contract in each pool, so a vendor can have up to six.

Pool

The six OASIS+ contract families: Small Business, 8(a), WOSB, SDVOSB, HUBZone, Unrestricted. The short label UNR means Unrestricted.

Status

Active and Dormant

The contract status exactly as GSA lists it. Search results, the home page grid, and most charts count active contracts only. Turn on "Include dormant" in search to count dormant ones too.

No longer listed

A contract that was on an earlier GSA list and is missing from the current one. It is hidden by default and kept for history. This site does not know why a contract left the list.

New and New contract

"New" marks a vendor that first appeared in the latest update. "New contract" marks an existing vendor that gained a contract in the latest update.

Domains and service lines

Domain

One of the 13 OASIS+ functional areas. The two-letter codes used here (MA, TE, and so on) were made up for this site to save space. They are not official GSA abbreviations.

Service line

A numbered line item on a contract (GSA calls it a SIN or CLIN), tied to a domain and usually to a NAICS code. The same service line exists in each pool under a different number; this site treats those as one line and shows which pools carry it.

NAICS not published

Some service lines are missing from GSA's own mapping of line numbers to NAICS codes. Those show "NAICS not published". It is a gap in the source file, not an error on the contract.

Service lines not yet published

A contract that GSA lists but has not yet added to its pool sheets. This is common for newly added contracts.

What the counts mean

Search results

Count vendors. A vendor with three matching contracts appears once.

Home page grid and "Contracts per domain"

Count active contracts in a pool that carry at least one service line in the domain. Because a vendor has at most one contract per pool, each grid cell also equals the number of vendors you get by selecting it.

Pool combinations and "Pools per vendor"

Count vendors by the pools they hold, including dormant contracts.

State

Not in the GSA file. It is worked out from the ZIP code of the vendor's address, so it reflects the mailing address on the contract, not where work is performed.

Who can bid

Who can bid lists the vendors whose contract in one pool carries the domains, service lines, or NAICS codes you choose. Matching uses that pool's contract only: a domain the vendor holds in a different pool does not count.

It shows what is on the contract. It does not confirm a company's current size status, certifications, or anything else a contracting officer checks before an award.

History and contacts

History

Changes are found by comparing each new GSA file with the one before it. Tracking began with the 10/26/2026 file, so "First tracked" is that date, not the date the contract was awarded.

Contacts

The contract manager and program manager GSA lists for each contract. A vendor with several contracts may list different people on each. Email addresses appear only when you select "Show email".

Not included

Task order awards, obligations, SAM.gov registration details, and subcontractor or teaming relationships are not part of the GSA list and are not shown here.
