# Official U.S. government funding & contract sources

**29 sources · 19 issuing authorities · compiled 19 August 2026**

Every entry is an official government or official program page — no aggregators,
no paid databases, no scraped listings. This is the exact registry monitored by
CodeBody Dynamics' funding scout.

Where a source refuses an identifying crawler, that is stated. It is useful to
know before you build anything against it.

## How to use this

1. **Start with three, not twenty-nine.** Pick the ones matching your NAICS codes.
2. **The official source is authoritative.** A search result or a newsletter can
   surface a lead; only the official page proves a deadline or an application path.
3. **Register before you need to.** SAM.gov entity registration takes weeks and
   gates every federal award. Cal eProcure and municipal portals are days.
4. **Watch closing dates, not postings.** Most opportunities are lost to a missed
   date, not a lost competition.
