Registrants who opted out of public display in SAM.gov (31,437 in this extract) are excluded from every product. Built from the SAM.gov public entity extract — the monthly file the General Services Administration publishes of every registration in the System for Award Management, decoded with GSA's own layout, the Census NAICS list and the GSA PSC manual.

✓Where this data comes from
This dataset is built from the SAM.gov public entity extract — the monthly file the General Services Administration publishes of every registration in the System for Award Management, the register every organisation must be in before it can receive a federal contract or grant. Every row is the entity's own registration, keyed by its permanent Unique Entity ID, with its business types, NAICS and PSC codes decoded from GSA's published layout, the Census NAICS list and the GSA PSC manual. Nothing comes from a company's website. Three public government sources are joined on top, each named on every row it fills: USAspending contract records (fiscal 2021 onward) for award counts, dollars obligated, officer compensation, links to the awards, and the telephone number on the latest contract; SBA Small Business Search profiles, joined on UEI, for the email address and phone a firm chooses to publish; and SBA Paycheck Protection Program loan records, joined on name and ZIP, for the headcount a business reported in 2020–21. Email domains are checked for a mail record on every build; mailboxes are not.

Registrations are published as SAM holds them. The only rows removed are the registrants who set SAM's 'no public display' flag, which is honoured and counted on every dataset; expired registrations are kept in their own file rather than dropped. Dates are normalised to ISO and every code is decoded with the government's own tables, with the raw codes kept alongside. Every build round-trips a random sample against the live SAM.gov Entity Management API and is not published if any row disagrees.
How we build and date every file: methodology.
Using ChatGPT, Claude or an API?
No setup needed. Ask ChatGPT or Claude your question about the Federal Contractors — Mining, Quarrying, and Oil and Gas Extraction (NAICS 21) and give it this page: it can open https://locationlists.com/find?dataset=federal-contractors-mining-quarrying-and-oil-and-gas-extraction-naics-21 with the filters you need and show you the count and price.
Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.
How assistants ask
No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.
If a question needs filtering, distance, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.
Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>
Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&where=<column>:<op>:<value>&total=<rows>
Leave out what the question does not need. Distance is radius, in straight-line miles; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.

?Frequently Asked Questions
How many records are in Federal Contractors — Mining, Quarrying, and Oil and Gas Extraction (NAICS 21)?
Federal Contractors — Mining, Quarrying, and Oil and Gas Extraction (NAICS 21) holds 1,239 records in the US as of September 2026. They are in all 50 states, DC and Puerto Rico.
What is one row in this file?
One entity registration in SAM.gov, the System for Award Management every organisation must register in before it can receive a federal contract or grant. US federal contractors whose primary NAICS code falls in sector 21, Mining, Quarrying, and Oil and Gas Extraction — active SAM.gov registrations for contract awards. The row is keyed by the Unique Entity ID (UEI), which is permanent and is the same id USAspending and FPDS use.
Does it include email addresses or phone numbers?
Yes, from two public government sources, and every row says which. Telephone and fax come from the entity's most recent federal contract record in USAspending (FY2021–FY2026); where there is none, from the firm's own SBA Small Business Search profile. Email addresses come only from SBA profiles, and only where the firm chose to display them, so they are mostly small businesses. The SAM.gov extract itself carries contact names but no email or phone. Nothing is guessed or compiled from other lists, and no email is ever inferred from a website.
How often is it refreshed?
File built on September 15, 2026. It is not on an automatic refresh schedule, so check the build date above before you buy.
Is every SAM.gov registrant here?
Every registrant in the public extract except those who set the 'no public display' flag — 31,437 registrants in the 2026-09-06 file asked SAM not to show their registration in public search, and that request is honoured here even though the extract itself carries their records. Entities whose registration has expired are in the separate expired-registrations file, not this one.
How does this differ from USAspending or FPDS data?
SAM.gov records who is registered and eligible to receive an award; USAspending records the awards. This file joins the two on UEI: every registration, plus, for each one that won a contract FY2021–FY2026, the number of awards, dollars obligated in total and in the last 12 months, the top awarding agency, the contracting officer's size determination, the five highest-compensated officers where disclosed, and links to the largest and most recent award and the full USAspending recipient profile. The contract totals are reconciled to USAspending's own published totals for every closed fiscal year before a file is built.
How is the data verified?
A random sample of rows is round-tripped against the live SAM.gov Entity Management API on every build, comparing legal name, CAGE code, physical address, status and expiration date; a build with any disagreement is not published.
