Quick answer
An EPA-registered pesticide is a product the federal Environmental Protection Agency (EPA) has reviewed and allowed to be sold under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), shown by an “EPA Reg. No.” printed on its label.
Registration means the EPA judged the product will not cause unreasonable harm when used exactly as the label says. It is not an endorsement, a safety guarantee or proof that the product works.
Quick facts
The key facts about EPA-Registered Pesticide, with sources:
- Law
- Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 1
- Standard
- No “unreasonable adverse effects on the environment” when used per common practice (7 U.S.C. 136a(c)(5)) 1
- Number format
- “EPA Reg. No.” + company number + dash + product number 2
- Distributor products
- Three-part number, e.g. 262-598-10007 2
- Re-review
- Each registration reviewed at least once every 15 years 1

Key takeaways
- Almost every pesticide sold in the U.S. must be registered with the EPA before it can be sold.
- You can spot a registered product by the “EPA Reg. No.” on its label.
- Registration rests on safety and environmental data, and covers only the uses printed on the label.
- It is not an endorsement; the EPA says the number is not a stamp of approval or guarantee that the product works.
- Minimum risk products are exempt from registration and should not carry an EPA number.
What registration means in plain terms
Before a bug spray, ant bait or rat poison can be sold in the U.S., the company has to get permission from the EPA. That permission is called registration. The EPA says all pesticides sold or distributed in the U.S., including imports, must be registered 1.
In legal terms, registration is a license to sell a specific product with a specific label.
The company submits studies on the product’s chemistry, its effects on people and the environment, and, for food uses, residues on crops.
The EPA also looks at where the product is used, how much, how often and how it is stored and thrown away 1.
The decision standard is set in FIFRA. The applicant must show the product, used per widespread and commonly recognized practice, will not generally cause “unreasonable adverse effects on the environment” 1. Pesticides used on food also need a tolerance (a legal limit on residue) under the Federal Food, Drug, and Cosmetic Act 1.
The registration ties to the label. A product is registered for the pests, places and methods its label lists, and nothing else.
Registered does not mean safe or effective
The EPA’s Citizen’s Guide says the registration number shows the EPA reviewed the product and found it can be used with minimal or low risk if label directions are followed. It is “not a stamp of approval or guarantee of effectiveness” 4.
How a pesticide gets registered
The path from lab to store shelf follows a set order under FIFRA.
- Company number. The company gets a company number from the EPA 2.
- Application. The company submits the product’s full ingredient list, studies that meet EPA test guidelines, proof of a reliable manufacturing process, a proposed label and fees 1.
- File symbol. While under review, the product carries a temporary “file symbol” made of letters from the word REGULATION 2.
- Risk review. The EPA weighs risks and benefits for each use on the label 1.
- Label accepted. If approved, the letters become a product number and the label is accepted. The registration number is the company number, a dash and the product number 2.
- State registration. States also regulate pesticide sale and use and lead compliance and enforcement 1.
- Registration review. The EPA must re-review every registration at least once every 15 years 1.
- Company numberAssigned by EPA
- Application and dataStudies, ingredients, label, fees
- File symbole.g. 6767-EGN while under review
- EPA decisionNo unreasonable adverse effects when used per label
- EPA Reg. No.e.g. 6767-230 printed on the label
- ReviewAt least every 15 years
The REGULATION letter code: R=1, E=2, G=3 … N=0, so file symbol 6767-EGN becomes Reg. No. 6767-230. Source: [2] [1]
Kinds of registration and related numbers
| Type or number | What it means | How to spot it |
|---|---|---|
| Section 3 registration | Standard federal registration under FIFRA 2 | “EPA Reg. No.” with two parts, e.g. 6767-230 2 |
| Distributor (supplemental) registration | Same product sold under another company’s name; only the basic registrant can change the label 2 | Three-part number, e.g. 262-598-10007 2 |
| Special Local Need registration | A state-authorized use for a local need, if the EPA does not disapprove 12 | A state SLN number on supplemental labeling |
| EPA Establishment Number | The factory that last produced the product, not an approval 2 | “EPA Est.” with a state code, e.g. 98989-HI-002 2 |
| Restricted Use Pesticide | For certified applicators or people under their direct supervision only 6 | Not sold to the general public 6 |
| Minimum risk (exempt) | Exempt from FIFRA registration; listed ingredients only 5 | No EPA Reg. No.; all ingredients listed 5 |
The pesticide active ingredient page explains the ingredient statement printed next to these numbers.
Example: decoding registration numbers
These examples come straight from the EPA Label Review Manual (Chapter 14) and one EPA-accepted label. They show how to read what a number tells you.
| Number on the label | What each part means | What you learn |
|---|---|---|
| EPA Reg. No. 6767-230 | Company 6767, that company’s product 230 2 | A standard federal registration |
| EPA Reg. No. 262-598-10007 | Product 262-598 sold by distributor 10007 2 | Same product and label as 262-598 under another brand |
| EPA Est. 98989-HI-002 | Company 98989, made at its establishment 002 in Hawaii 2 | Where it was made; not an approval |
| File symbol 6767-EGN | E=2, G=3, N=0, so the future product number is 230 2 | Not yet registered |
| EPA Reg. No. 53883-261 | Company 53883, product 261 10 | A lambda-cyhalothrin product used in perimeter work |
EPA Reg. No. = company number – product number [– distributor number]
company number- Who holds the registration
product number- That company’s sequence number for the product
distributor number- Present only on supplemental distributor products

If a product shows letters where the product number should be, or no Reg. No. at all, it is either unregistered or claiming the minimum risk exemption. You can search the number in the EPA’s product label system to see the accepted label.
Where you will see the registration number
The product label is the first place to look. The number usually sits on the front panel near the company name and address. The EPA prefers that spot but does not require it, and the number must be printed in type similar to other label text 2.
Your pest control service ticket should also name the product. Many states require companies to record what they applied, so ask for the product name and EPA Reg. No. so you can look up the label. Our pesticide safety guide explains what to ask for.
During an emergency, the number helps responders. The EPA tells people calling 911 or Poison Control to have the product’s EPA registration number ready 7.
Safety data sheets carry it too. Pesticide SDSs often list the registration number in the identification or regulatory section. See safety data sheet.
What registration gives you
What it does
What it does not do
What registration does not cover
Registration is a decision about risk under a set of conditions. Change the conditions and the decision no longer holds. Using a termite product on fleas, for example, is off-label. The EPA’s guide says any use that does not match the label directions is illegal, and may also fail or be dangerous 4.
No registration is permanent. The EPA can change label terms during registration review, add limits or cancel uses. For example, the EPA lists pyrethroids and pyrethrins under class-wide review, with interim decisions and mitigation to reduce runoff and drift 9.
Federal registration is also only one layer. States can add their own registration and use rules, so a product sold in one state may not be allowed in another.
How registration affects cost
We do not list prices. Registration affects cost in a few indirect ways. Companies pay fees and fund studies to register a product, and those costs are part of product pricing.
Restricted use products can only be bought and applied by certified applicators 6, so treatments that need them must be done by a licensed company.
For a homeowner, the bigger cost question is the service, not the product. Ask a company which registered products a plan uses and why. Our pest control cost guide explains how quotes are built.
A registration has no fixed lifespan, but each one comes back for EPA review at least every 15 years 1. A label you read years ago may have changed, so the EPA tells users to re-read the label before each use 4.
How to check that a product is registered
Anyone can check a product in a few minutes, with nothing more than the label and a web browser.
- Find the number. Look for “EPA Reg. No.” or “EPA Registration No.” on the label 2.
- Check the format. Two parts for a standard product, three for a distributor product 2. Letters instead of numbers mean the product was not registered when printed.
- Look it up. Search the number in the EPA’s pesticide product label system or your state’s product database to see the accepted label.
- Compare the label. Check that the pests and sites on your package match the accepted label.
- Ask questions. The National Pesticide Information Center answers questions at 1-800-858-7378 8.
In an exposure, call first
If someone is unconscious, having trouble breathing or having convulsions, call 911. For first aid help, call Poison Control at 1-800-222-1222. Have the EPA registration number from the label ready 7.
How to keep track of products over time
- Keep products in their original containers so the label and Reg. No. stay with them 4.
- Re-read the label before each use; labels can change 4.
- Keep a list of what a pest company applies at your home, with Reg. Nos.
- Dispose of old products per the label’s storage and disposal section 4; see pesticide storage and disposal.
- Watch for EPA actions on ingredients you use often; status is posted on EPA ingredient pages 9.
Red flags and when to report
- No EPA Reg. No. on a product that claims to kill pests, unless it lists only minimum risk ingredients 5.
- A minimum risk product that shows an EPA number, which the EPA says is likely misleading 5.
- Labels or ads that claim “safe,” “nontoxic” or “harmless,” which FIFRA rules treat as misbranding 3.
- Claims that a product is endorsed by a federal agency, which are also barred 3.
- Products sold in unlabeled bottles or bags; NPIC says never use an unlabeled pesticide 8.
Report suspect products to your state pesticide regulatory agency or the EPA.
The rules behind registration
Federal statute. FIFRA (7 U.S.C. 136 et seq.) requires registration and sets the “unreasonable adverse effects” standard at 7 U.S.C. 136a(c)(5) 1. FIFRA Section 12(a)(1)(E) makes selling a misbranded pesticide unlawful 3.
Label rules. 40 CFR 156.10 requires the registration number and establishment number on every product 2. 40 CFR 156.10(a)(5) lists false or misleading claims, including safety claims 3.
Food uses. Tolerances are set under the Federal Food, Drug, and Cosmetic Act; the Food Quality Protection Act requires a “reasonable certainty of no harm” 1.
Exemptions. Minimum risk pesticides that meet six conditions in 40 CFR 152.25(f) are exempt from federal registration; states regulate them 5.
Restricted use. Restricted use products may be used only by certified applicators or under their direct supervision 6. States run the certification. See pest control licensing.
Registered vs minimum risk vs unregistered
| Status | EPA review? | Label shows | Can it claim to control disease-carrying pests? |
|---|---|---|---|
| EPA-registered | Yes 1 | EPA Reg. No. and Est. No. 2 | Only if the accepted label allows it |
| Minimum risk (25(b) exempt) | No 5 | All ingredients; no EPA number 5 | No; health-related claims are barred 5 |
| Unregistered pesticide | No | No valid number | Illegal to sell or distribute as a pesticide 1 |
See the pesticide label page for the full list of label sections.
Myths about EPA registration
- Myth EPA-registered means EPA-approved and safe.
- Reality The EPA says the number is not a stamp of approval or guarantee of effectiveness 4. Labels may not even claim “safe” 3.
- Myth A registered product can be used on any pest.
- Reality Only on pests and sites the label lists; other use is illegal 4.
- Myth “Natural” products do not need to follow rules.
- Reality EPA policy does not allow “natural” on registered labels because it can read as a safety claim 3. Exempt products still have conditions 5.
- Myth An EPA Est. number means the product is registered.
- Reality The establishment number only identifies the factory 2.
- Myth Registration lasts forever.
- Reality Each registration is reviewed at least every 15 years 1.
State rules on top of federal registration
The EPA works with states, and states have the main role in compliance monitoring and enforcement. States can also authorize Special Local Need uses if the EPA does not disapprove 1.
California is one state that has gone further: its Department of Pesticide Regulation reevaluated 608 pyrethroid products and adopted its own outdoor-use rules in 2012 11.
Check your state pesticide agency for products allowed there, and check that any company applying them is licensed.
When to check the registration number
Before you buy or allow any pest product at home, find the EPA Reg. No. and check that your pest and your site are on the label. If there is no number, check whether it is a minimum risk product with all ingredients listed; if not, do not use it.
When hiring a company, ask for the product names and Reg. Nos. they plan to use, and keep the service ticket. Our guide to choosing a pest control company covers the other questions, and our IPM guide explains when a pesticide is needed at all.
Quick decision guide
If the Reg. No. is there and your pest is listed, read the full label before use. If there is no number, look for the minimum risk ingredient list, and skip the product if it is missing. If a company is treating, ask for product names and Reg. Nos.
Questions about EPA-Registered Pesticide
What does EPA-registered mean on a pesticide?
It means the EPA reviewed the product under FIFRA and allowed it to be sold with a specific label.
The EPA found it will not cause unreasonable harm when used exactly as the label directs. It is not an endorsement or a guarantee that the product works or is safe if misused. The label shows an “EPA Reg. No.”
How do I find the EPA registration number?
Look on the product label for “EPA Reg. No.” or “EPA Registration No.” followed by numbers separated by dashes. The EPA prefers it on the front panel near the company name and address, but it can appear elsewhere on the label. A three-part number means a distributor sells the product under its own brand.
Is an EPA-registered pesticide safe?
Not automatically. Registration means the EPA judged risks acceptable when label directions are followed. The EPA’s own guide says the number is not a stamp of approval or guarantee of effectiveness. Labels are not even allowed to say a product is “safe,” “nontoxic” or “harmless.” Follow the label exactly.
What is the difference between an EPA Reg. No. and an EPA Est. No.?
The EPA Reg. No. identifies the registered product and the company that holds the registration. The EPA Est. No. identifies the factory where the product was last made, with a state code such as MO or HI. Only the registration number tells you the product was registered.
Why do some pest products have no EPA number?
Some are minimum risk pesticides, which are exempt from federal registration if they use only listed ingredients and meet six EPA conditions. They must list all ingredients and cannot claim to control disease-carrying pests. The EPA says showing an EPA number on these products is likely misleading. Other products with no number may be illegal.
Can a company use any registered pesticide in my home?
No. They may only use products whose labels list your site and pest, and only as the label directs. Some products are restricted use, meaning only certified applicators or people they directly supervise may apply them. Ask the company for the product names and registration numbers they plan to use.
How often does the EPA review pesticides?
The EPA must review each pesticide registration at least once every 15 years. Reviews can add restrictions, change labels or cancel uses. For example, pyrethroids and pyrethrins are being reviewed as a class, with mitigation to reduce runoff and drift. Status is posted on EPA ingredient pages.
What should I do if someone is exposed to a pesticide?
If the person is unconscious, having trouble breathing or having convulsions, call 911. Otherwise call Poison Control at 1-800-222-1222 for first aid help. Check the label’s first aid section and have the EPA registration number ready. For non-emergency questions, the National Pesticide Information Center is at 1-800-858-7378.
Do states also register pesticides?
States regulate pesticide sale and use alongside the EPA and lead compliance and enforcement. They can authorize Special Local Need uses if the EPA does not object, and they regulate minimum risk products. Some states, such as California, add their own reviews and use rules. Check your state pesticide agency.
