NPIP certification explained: what buyers should ask, what breeders need to know

7 minute read · published 2026-05-04

If you're buying live birds or hatching eggs across state lines, the three letters that matter most are NPIP: the National Poultry Improvement Plan. It's a USDA-state cooperative program that certifies flocks free from specific reportable diseases. Most US states require NPIP certification on interstate shipments. Here's the working knowledge a buyer or a breeder needs.

What NPIP actually certifies

NPIP is not a single certification. It's a tiered set of disease-free statuses a flock can hold, including:

• Pullorum-Typhoid Clean (the baseline). Required for almost any interstate poultry shipment. The flock tests negative for Salmonella pullorum.
• Mycoplasma Clean (M. gallisepticum, M. synoviae). A separate test, often required by show circuits and most state import permits for breeding stock.
• Avian Influenza (AI) Monitored / AI Clean. Surveillance-based status. Especially important in 2026 with HPAI outbreaks ongoing.
• Salmonella Enteritidis Monitored. Optional, primarily for table-egg producers.

A breeder may carry one, several, or all of these. The phrase "NPIP certified" alone means the bare-minimum Pullorum-Typhoid status. Always ask which programs the flock participates in.

How to read an NPIP number

An NPIP number looks like 12-345. The first segment is the state ID (00-99); the second is the flock's assigned number within that state. For example:

• 12-345 = state code 12 (Iowa), flock 345
• 74-002 = state code 74 (North Carolina), flock 2

You can verify any NPIP number at the USDA's online lookup: poultryimprovement.org. A valid number plus a current participation list is the only proof that matters.

What NPIP does not tell you

NPIP is a disease-surveillance program. It doesn't certify:

• Breed purity. NPIP cares about disease, not pedigree. APA recognition is a separate question.
• Husbandry quality. A flock can be NPIP-clean and still be raised in poor conditions.
• Genetic stock quality. Show-quality vs. hatchery-stock distinctions are not part of NPIP.

Buyer's question list

Before paying a breeder for interstate shipment, ask:

1. What is your NPIP number, and which programs does the flock participate in?
2. Are your hatching eggs and chicks both covered, or chicks only?
3. Will you provide a VS Form 9-3 or a state-required health certificate at shipment time?
4. What's your AI-monitoring frequency and date of last clean test?
5. Do you vaccinate for Marek's disease at hatch?

A serious breeder answers all five in one email. If you get vague answers, walk away.

State-by-state import rules

Even with NPIP, several states impose extra rules. A few examples for 2026:

• California: Requires permit and registration before live bird import in many counties.
• New York: Health certificate required; some counties restrict adult bird imports.
• Georgia: Strict AI monitoring requirements for adult stock; eggs and day-olds are easier.
• Hawaii, Alaska, Puerto Rico, USVI: Severely restricted or prohibited - assume "no" until proven otherwise.

We maintain a state-by-state cheat sheet we update quarterly. Always confirm with your state's Department of Agriculture before any shipment.

What to do if a breeder isn't NPIP

Hobby breeders without NPIP are common, especially at the local-pickup level. For in-state pickup of small numbers, NPIP isn't legally required. For any interstate shipment, NPIP (or an equivalent state-issued health certificate) is non-negotiable. If a breeder ships across state lines without one and you accept, you're both technically in violation of the rules.

For breeders: getting NPIP-certified

The process is simpler than most assume. Contact your state poultry health authority (links at poultryimprovement.org). A state-licensed tester will visit (or train you for self-testing), pull blood samples, and submit them. Annual recertification typically runs $25-150 depending on flock size. The certification opens you to interstate sales and earns the verified badge on your marketplace listings.

The bottom line

NPIP is the single most important question a poultry buyer can ask. It's not perfect (it doesn't catch everything, and it doesn't certify breed quality), but it's the universal industry baseline for disease-free interstate shipment. Look for the green NPIP badge on every listing, and don't pay for interstate shipment without seeing the number.
