State Register vs. Administrative Code: What Each One Is

Short answer: a state register is the periodical where a state prints rule notices as they happen. That means proposed rules, adopted rules, emergency rules and agency announcements. A state administrative code is the organized set of rules in force today, grouped by agency and subject. The register shows what is coming or just changed. The code shows the rule as it reads now. Each of the five states checked for this guide keeps both, under different names. A rule moves from the first to the second once it is adopted.

TL;DR

• Register: a weekly or twice-monthly journal. A proposed rule shows up here first, with a comment deadline.
• Administrative code: the rules in force. A rule joins it only after it is adopted and takes effect.
• The names differ. Texas has the Texas Register and the Texas Administrative Code. New York has the State Register and the New York Codes, Rules and Regulations, called NYCRR. Pennsylvania calls its register the Pennsylvania Bulletin.
• Not every online copy is official. New York's free NYCRR site calls itself unofficial. California's free online code is the official one. Check before you cite.
• A proposed rule is not law. Cite the code, and check the register for anything adopted since the code was last updated.

What a state register is, and what an administrative code is

A state agency, such as a licensing board, writes rules under power that a statute gave it. A statute is a law passed by a legislature. Our guide to how a regulation differs from a statute covers that link. The rules need homes. States use two publications.

The register is like a government newspaper for rules. Its job is notice. Texas says so in its statute. State policy is to give "adequate and proper public notice of proposed state agency rules and state agency actions through publication of a state register" (Texas Government Code section 2002.002). A register also carries items that are not rules, such as hearing dates. In Texas it also carries the governor's executive orders and summaries of attorney general opinions.

The administrative code is the reference book. It holds each rule in force, sorted by agency, and it is revised as rules change. Texas tells its secretary of state to "compile, index, and publish a Texas Administrative Code" (section 2002.051).

Some states use other names. Pennsylvania's register is the Pennsylvania Bulletin, and its code is the Pennsylvania Code. The idea is the same. Notices go in the register. Finished rules go in the code. The federal pair is the Federal Register and the Code of Federal Regulations. Our Federal Register guide covers them.

In some states, "state register" also means a list of historic places. This guide is only about rules.

How a rule moves from the register to the code

The steps look alike everywhere, even though the deadlines differ.

1. The agency files a proposal. The register prints the proposed text or a summary. It also prints the hearing date, the comment deadline and a contact person.
2. The public comments. State law sets the minimum notice or comment time. In the five states below it runs from 20 to 60 days.
3. The agency decides. It can adopt the rule, change it, or drop it. A big change often means a second round of comment.
4. The agency files the adopted rule. The register prints a notice of adoption, usually with the date the rule takes effect.
5. The rule takes effect. The date comes from state law or from the rule itself.
6. The code is updated. The rule joins the code. How fast depends on the state.

The gap between steps 4 and 6 catches people. For days or weeks, a rule can be in effect while the code does not show it.

Five states, five systems

Check three things first: the comment deadline, whether the online copy is official, and whether a newer adopted rule still sits in the register. Each state's own pages were checked on 5 October 2026. These five states are a sample, so other states differ. Comment periods, publication schedules and official-copy statements can change, so confirm what matters on the state's site.

Sources for the table are the state pages linked in the paragraphs below.

Texas. The Texas Secretary of State publishes the Texas Register. It carries "proposed, adopted, withdrawn, and emergency rule actions." Adopted rules go into the Texas Administrative Code, which has 17 titles. An agency must give at least 30 days' notice before it adopts a rule (section 2001.023). A rule takes effect 20 days after filing unless a later date applies (section 2001.036). Two details trip people up. A proposal not adopted within six months is withdrawn (section 2001.027). And the code "may not contain emergency rules" (section 2002.051), so those live only in the register.

A Texas rule also points back to the register. Take section 91.6 of title 1 of the Texas Administrative Code, written 1 TAC section 91.6. It covers register deadlines. Its history line ends with "28 TexReg 2303." TexReg is short for Texas Register, so that means volume 28, page 2303, where the rule first ran.

New York. The Department of State publishes the State Register each week. After a proposal appears, the agency must take comment for at least 60 days. After a big change, it must publish a revised notice and take comment for at least 45 more days. Each weekly Register includes an Action Pending Index. It lists every proposed rule still under consideration, so tracking is easy. The free online NYCRR is different. Its own front page calls it "an unofficial version." It adds that this version "should not be used for evidentiary or any other official purpose," which means it is not for use as proof or for official business.

California. The Office of Administrative Law (OAL) publishes the Notice Register every Friday. It also publishes the California Code of Regulations, known as the CCR. Three features stand out. First, OAL checks each regulation. It must approve or reject it within 30 working days (Government Code section 11349.3). Second, approved regulations take effect on set dates: January 1, April 1, July 1 or October 1. A statute or the agency can pick another date (section 11343.4). Third, the free online CCR is the official one. OAL says it contracts with Thomson Reuters for "a free online version of the Official CCR." It warns that it "cannot verify the authenticity of regulations downloaded from websites other than this site." Title 24, the building standards code, is kept elsewhere. The online CCR leaves it out.

Virginia. The Virginia Register of Regulations comes out every other Monday, 26 issues a year. A regulation goes through three steps. A notice of intended action opens at least 30 days of comment. The proposal then gets 60 days. The final text is published and waits 30 days before it takes effect. The Register's FAQ says "the official Virginia Register is the pdf version posted online." State law adds that "no regulation or amendment or repeal thereof shall be effective until filed with the Registrar" (Code of Virginia section 2.2-4103). Citations tell you where to look. "28:2 VA.R. 47-141" means volume 28, issue 2, pages 47 to 141 of the Virginia Register.

Washington. The Washington State Register comes out twice a month. Washington adds an early step before a formal proposal. It is called a "preproposal statement of inquiry," and it tells the public the agency is thinking about a rule. The notice of a rule-making hearing must run at least 20 days before the hearing (Revised Code of Washington, or RCW, section 34.05.320). A rule takes effect 30 days after filing unless the law or the agency sets a later date (RCW section 34.05.380). The Statute Law Committee says the certified PDFs on the website of the Code Reviser, the state office that compiles the rules, are the official Register and the official WAC. The WAC web pages update twice a month.

How to find a rule before it takes effect

1. Open the current register issue. Find the section for proposed rules. Most registers split each issue by stage, such as proposed, adopted and emergency.
2. Search by agency or topic. Washington has an agency-to-title list. New York has the Action Pending Index. Texas has a searchable archive that starts in 2000.
3. Work backward from a code section. A Texas history line points to a register page. Washington has a table that links each WAC section to its register filing.
4. Subscribe. New York sends email alerts when each issue is posted. Virginia has an RSS feed, a free way to get an alert for each new issue. Virginia also has the Regulatory Town Hall, a state site where the public can follow regulations and comment.
5. Read four things in the notice. Find the comment deadline, where to send comments, whether there is a hearing, and the agency contact.
6. Look again later for the notice of adoption. The text may have changed since the proposal.

Commenting works much like the federal process in our guide to notice and comment rulemaking.

Common mistakes

• Citing a proposed rule as law. A proposal has no force until it is adopted and takes effect. It may also change or lapse. Texas withdraws proposals after six months.
• Reading only the code. An adopted rule may sit in the register for weeks before the code shows it. New York's free site says its dates follow the last print supplement. It adds that later Register issues "may contain subsequent rule adoptions."
• Using a copy that is not official. Free sites, law firm PDFs and old downloads are handy. In some states, the state itself says they are not the official text. Our note on legal data provenance shows how to check.
• Hunting for emergency rules in the code. In Texas they are not printed there.
• Mixing up adoption and effective dates. In New York, a rule adopted today can take effect when its notice of adoption is published.
• Citing guidance as a rule. Virginia's Register prints agency guidance documents. It says they lack "the force and effect of law."

Before you cite a state rule, write down the full code citation, the agency and the date you read it. Our guide to citing a statute or regulation shows the format. This is general information, not legal advice.

FAQ

What is a state register? It is the official periodical where a state prints rule notices as they happen. Some states call it a bulletin or an administrative register.

What is the difference between a state register and an administrative code? The register is a running record of rule changes, published every week or two. The code is the organized set of rules in force. Read the register to see what is coming. Read the code to see what applies today.

Is the online version of my state's administrative code official? It depends on the state. California says its free online code is the official version. New York's free site says it is unofficial. Washington names certified PDFs as official. Look for a statement on the state's own site.

Do states have to publish a rule as a proposal first? Generally yes. All five states above require a published proposal and a comment period for ordinary rules. Emergency rules are the exception. Texas lets an agency adopt an emergency rule without prior notice. Virginia lets one take effect the day it is filed.

How do I find a proposed rule in my state? Go to the state's register website and open the newest issue. Look for the proposed rules section, or search by agency name. Many states also let you sign up for an email or RSS alert.

How long do I have to comment on a proposed rule? It depends on the state and the rule. Among the five covered here, the minimum runs from a 20-day notice before a Washington hearing to 60 days in New York and Virginia. The notice itself gives the real deadline.

Is there a federal version? Yes. The Federal Register carries federal proposed and final rules. The Code of Federal Regulations holds those in force. Our US Law Data guide maps where each kind of law lives.
