How to understand the FAR without reading all of it
The Federal Acquisition Regulation has 51 parts and 3,399 sections. Which parts to read first, how to find the section you need, plain-English guides and answers cited to the text.
The answer in one paragraph
You don't need to read it all. The Federal Acquisition Regulation (FAR, 48 CFR chapter 1, the rules for how federal agencies buy, not the aviation rules in 14 CFR) has 51 parts and 3,399 sections. Start with the handful of parts for what you're doing, search for the topic instead of reading in order, and read a plain-English summary before the legal text. SpendQuery's free FAR navigator has every part and section, a plain-English guide to each part and Ask the FAR, which answers questions with citations to the exact sections.
The parts to read first
| Part | What it covers | Sections |
|---|---|---|
| Part 2 | Definitions (what “commercial product” or “simplified acquisition threshold” means) | 3 |
| Part 4 | SAM registration, the UEI, safeguarding information | 116 |
| Part 12 | Commercial products and services: how most purchases are made | 38 |
| Part 13 | Simplified acquisitions: buys under $350,000 | 49 |
| Part 15 | Contracting by negotiation: proposals, evaluation, debriefings | 81 |
| Part 19 | Small business programs and set-asides | 126 |
| Part 32 | Contract financing and getting paid | 175 |
| Part 52 | The clauses in your contract | 680 |
Section counts from the eCFR as of October 13, 2026. Defense contracts add the DFARS (48 CFR chapter 2).
Find the section you need
- Search by words (“limitations on subcontracting”) or jump to a section number (52.219-14) instead of reading in order.
- Read the part's plain-English guide first: what it applies to, what you must do, the key terms.
- Ask the FAR in a sentence (“When must I be registered in SAM?”) and get the answer with the sections it rests on, then read those sections.
- In a solicitation, read the clauses it lists in Section I and the evaluation criteria in Section M: those are the rules for that buy.
Is the text current?
The navigator shows the codified FAR from the eCFR, dated. Under the Revolutionary FAR Overhaul (2025 to 2026), agencies follow class deviations with rewritten text for many parts while the formal rules go through the Federal Register, so check which version your solicitation applies. SpendQuery's rule changes page lists the proposed and final FAR, DFARS and SBA rules and their dates.
