How Many Laws Are There in the U.S.?
Updated August 10, 2026
There is no official, universally accepted number for how many laws exist in the United States — and that's not because no one has tried to count. Government bodies, including the Department of Justice and the American Bar Association, have made serious attempts to count even a single narrow category (federal criminal laws) and each concluded that a precise count isn't realistically achievable. This guide explains why, and what you can actually say about the scope of American law with confidence.
Why There's No Single Answer
"How many laws" depends entirely on what you count. Do you mean federal statutes only, or also federal regulations (which carry the force of law)? Just criminal laws, or civil ones too? Only the 50 states' statutes, or also every county and municipal ordinance in the country? Each of these categories is large, none of them is centrally or uniformly tracked in a single count, and they change constantly as legislatures and agencies act. Any single number you see cited is really an answer to a much narrower question than "how many laws are there."
Federal Statutes
Congress's enacted laws are organized into the United States Code, which is divided into 50 broad subject titles (like Title 18 for crimes, Title 26 for taxes, and Title 42 for public health and welfare). The Code is continuously amended — provisions are added, repealed, and revised every time Congress passes new legislation — so its total size is a moving target, not a fixed number.
Federal Regulations
Beyond statutes, federal agencies issue regulations under authority Congress delegates to them, compiled in the Code of Federal Regulations (CFR). The CFR is also organized into 50 titles and runs to roughly 200 volumes, updated on a rolling quarterly schedule. Regulations carry legal force — violating one can carry the same real consequences as violating a statute — which is part of why "how many federal laws" and "how many federal statutes" aren't the same question.
State Statutes
Each of the 50 states (plus D.C. and the territories) maintains its own state code, covering everything from criminal law to family law to business regulation. There is no single combined count of "all state laws" because each state's legislature and code are independent of the others, and each changes on its own schedule every legislative session.
State Regulations
Just as federal agencies issue regulations, so do state agencies — a state's department of health, environment, insurance, or professional licensing boards, for example. State regulatory codes exist in every state, add substantially to each state's total body of law, and, like the CFR, are updated continuously.
Local Ordinances
Below the state level, the United States has thousands of local governments — more than 3,000 counties alone, plus cities, towns, and other municipalities — each with authority (delegated by its state) to pass local ordinances covering things like zoning, noise, building codes, and business licensing. There is no national database that aggregates every local ordinance in the country, which makes this layer of law the hardest of all to count.
Court Rules and Administrative Rules
Beyond legislatively enacted law, both federal and state court systems maintain their own procedural rules (like the Federal Rules of Civil Procedure), and administrative agencies often have internal rules governing their own proceedings. These aren't "laws" in the statutory sense, but they carry binding legal effect within their own systems and add another layer to any attempt at a comprehensive count.
Why Estimates Differ So Much
The clearest illustration of why no exact number exists comes from attempts to count just one category: federal crimes.
- In 1982, the U.S. Department of Justice undertook a two-year effort to count federal criminal offenses and arrived at an estimate of roughly 3,000.
- In 1998, the American Bar Association attempted its own count and concluded it lacked the resources to replicate or verify that kind of comprehensive review.
- More recent estimates by legal researchers have put the number of distinct federal statutory crimes at somewhere between roughly 4,000 and 5,000, with a much larger — and explicitly uncertain — number of federal regulations (some estimates run into the hundreds of thousands) that can also carry criminal penalties.
If experts can't agree on a precise number for federal crimes alone — a small subset of federal law, which is itself a small subset of all U.S. law — a confident total for "all laws in the U.S." isn't something any credible source can actually produce.
Statute, Regulation, Ordinance, and Case Law: What's the Difference?
| Type | Who creates it | Example |
|---|---|---|
| Statute | A legislature (Congress or a state legislature) | A state's criminal code provision |
| Regulation | An administrative agency, under authority delegated by statute | An EPA emissions rule |
| Ordinance | A local government (city or county), under authority delegated by the state | A local noise or zoning ordinance |
| Case law | Courts, interpreting constitutions, statutes, and regulations | A published appellate court decision setting precedent |
Each category is created differently, by a different kind of body, and each is tracked (if at all) in a different system — which is another reason a single combined count doesn't exist.
Why the Number Keeps Changing
Even if someone produced an accurate count on a given day, it would be outdated almost immediately. Congress and every state legislature pass new statutes and repeal old ones every session; federal and state agencies issue new regulations and revise or withdraw old ones on a rolling basis; and local governments amend ordinances continuously. "How many laws exist" isn't a fixed fact waiting to be discovered — it's a constantly moving number.
How Federal and State Law Interact
Federal and state law aren't simply added together into one master list — they interact. Under the Constitution's Supremacy Clause, valid federal law overrides conflicting state law in areas where the federal government has authority to act, while, under the Tenth Amendment, powers the Constitution doesn't grant to the federal government are reserved to the states. Our guide to the Constitution and how federal laws are made explains how federal statutes come into being in the first place, and our broader guide to how the U.S. legal system works explains how federal, state, and local law fit together as a system.
How to Find the Laws That Actually Apply to You
Instead of trying to answer "how many laws exist," it's far more useful — and far more achievable — to identify the specific laws that apply to your actual situation: the relevant provisions of your state's code, any applicable local ordinances, and, where relevant, the specific federal statute or regulation at issue. Official government sources — Congress.gov and the CFR for federal law, and your state legislature's or state courts' official website for state law — are the most reliable places to find current, accurate text, rather than relying on a secondhand estimate of the total number of laws in the country.

Frequently Asked Questions
So how many laws are there in the U.S. — even roughly?
No credible source can give an accurate total, because "laws" spans federal statutes, federal regulations, 50 separate state codes and their regulations, thousands of local ordinances, and court rules — none of which is centrally counted, and all of which change constantly.
Has anyone ever tried to count them?
Yes, though generally only within narrower categories. The Department of Justice's 1982 review of federal criminal law and the American Bar Association's 1998 attempt are two well-documented examples, and both illustrate how difficult even a partial count is.
Why do some articles state a specific, exact number?
Often because they're citing a rough or dated estimate for one narrow category (like federal crimes) and presenting it as though it describes "all U.S. law." Always check exactly what a cited number is counting, and when the count was made, before relying on it.
Is the number of laws increasing over time?
In general, the volume of federal and state statutes and regulations has grown substantially over the country's history, though legislatures and agencies also repeal or simplify existing law, so growth isn't uniform across every category or every period.
