CVI Health Certificate: The Complete 2026 Guide to Certificates of Veterinary Inspection

A CVI health certificate — short for Certificate of Veterinary Inspection — is an official document that a USDA-accredited veterinarian issues after examining an animal, certifying it shows no signs of contagious disease and meets the receiving state's or country's entry rules. It is required for most interstate and international animal movement in the United States and is usually valid for 30 days from the exam date. It is not a diagnosis, a vaccination record on its own, or a government travel visa.

What Is a CVI Health Certificate?

CVI stands for Certificate of Veterinary Inspection. The American Veterinary Medical Association (AVMA) and multiple state agriculture departments describe it as the standard paperwork proving an animal was inspected by an accredited veterinarian and found free of communicable disease before moving within a state, between states, or across a border. Because it certifies a health status at a point in time, farmers, breeders, show exhibitors, and pet owners often call it simply a "health certificate."

The certificate typically records the animal's species, breed, sex, age, and identifying marks; the owner's and destination contact information; a summary of the veterinary exam findings; and, for some species, recent test results such as a Coggins test for equine infectious anemia (EIA). The Pennsylvania State University Extension notes that horse CVIs specifically must list "Veterinarian Information: Name, Clinic, Accreditation Number, Address" along with the exam date and certificate number (Penn State Extension, 2024).

Who Can Issue a CVI?

Only a USDA-accredited veterinarian can legally issue a CVI — a veterinarian with a standard state license cannot sign one without this additional federal accreditation. Accreditation comes in two tiers:

• Category I — covers most companion animals but excludes food and fiber species, horses, birds, farm-raised aquatic animals, other livestock, and zoo animals capable of transmitting disease to livestock.
• Category II — covers all animal species, including livestock, poultry, and exotics.

This two-tier structure is confirmed across state veterinary program summaries referencing USDA accreditation rules. In practice, if you need a CVI for cattle, horses, or poultry, confirm your veterinarian holds Category II accreditation before scheduling the exam.

How Long Is a CVI Valid?

Most states accept a CVI for 30 days from the date of examination. Some states extend this window for specific circumstances — Penn State Extension reports that certain equine CVIs "typically expire after thirty days, but some states may allow for extensions up to six months," depending on the destination state's regulations (Penn State Extension, 2024). Because validity periods and required lab tests vary by state and species, always confirm the receiving state's exact rules before travel — USDA APHIS explicitly states that "domestic movement requirements are set by the receiving State or Territory," not by the federal government (USDA APHIS, 2026).

Paper vs. Electronic CVIs (eCVI)

Health certificates can be issued on paper or electronically. Electronic CVIs (eCVIs) route directly to state animal health officials for faster review and better disease-traceability records. The California Department of Food and Agriculture (CDFA) lists several state-approved eCVI platforms — including VSPS-USDA APHIS, GlobalVetLink, Vet Sentry, myVetTech, and the equine-specific EquiPass — and notes that eCVIs are "only intended for domestic travel," since international movement still requires "USDA sanctioned forms" (CDFA, accessed 2026). Some destination states now accept electronic certificates only, so confirm the required format with the destination state before your veterinary visit.

USDA's Free VSPS System

USDA APHIS runs its own free platform, the Veterinary Services Process Streamlining (VSPS) system, which accredited veterinarians use to generate electronic CVIs for interstate livestock movement — including alpaca, bison, bovine, caprine, cervidae, equine, llama, ovine, and porcine species (USDA APHIS, 2025). A key limitation: VSPS does not currently issue CVIs for companion animals such as cats and dogs — those go through commercial eCVI providers or paper forms instead (USDA APHIS, 2025).

Does a CVI Cover International Travel?

For animals leaving the U.S., a domestic CVI is usually just the first step; the destination country typically requires its own international health certificate, often endorsed by a federal veterinarian. For animals entering the U.S., requirements differ by species and origin country and are set by USDA APHIS and, for dogs specifically, by the Centers for Disease Control and Prevention (CDC), which focuses on rabies-vaccination and microchip documentation for dogs arriving from countries at high risk for dog rabies, rather than a general CVI.

CVI vs. EU Pet Passport: Not the Same Document

A U.S. CVI is frequently confused with the European Union pet passport, but they are governed by different authorities and serve different purposes. The table below summarizes the distinction.

The European Commission describes the EU pet passport as an official document "completed and issued by an authorised veterinarian" that records a pet's microchip code and rabies vaccination status, and it is issued only to EU residents (European Commission, Food Safety, accessed 2026). A U.S. CVI is a broader, shorter-validity inspection document used mainly for domestic livestock and companion-animal movement, and it does not follow EU regulation at all. If you are researching pet travel to or within Europe, read the EU-specific rules rather than assuming a U.S. CVI will satisfy them — Animal Passport covers that distinction in more depth in its EU dog passport guide.

Step-by-Step: How to Get a CVI Health Certificate

1. Confirm the destination state or country's requirements before scheduling, since rules and required tests vary.
2. Find a USDA-accredited veterinarian in the correct accreditation category for your species.
3. Schedule the exam close to travel — most certificates are only valid for 30 days.
4. Bring vaccination and identification records so the vet can verify and document them.
5. Complete any required testing (for example, a Coggins test for horses) with enough lead time for lab results.
6. Receive the paper or electronic CVI and confirm it was submitted to the destination state's animal health office if required.
7. Carry the certificate (or confirm electronic delivery) for the entire trip, since some carriers and checkpoints request to see it directly.

Why Livestock Identity Matters Alongside the CVI

A CVI documents an animal's health on a single day — it does not, by itself, prove which physical animal it belongs to if paperwork is lost, damaged, or separated from the animal during an emergency. This gap became visible during flooding in Pakistan in August 2025, when paper ear tags washed away and farmers struggled to reclaim livestock. In that event, Animal Passport's phone-based muzzle biometric ID — which captures an animal's nose print, similar to a human fingerprint — let farmers re-match animals to owner records after physical tags were lost. Animal Passport uses a phone camera to record muzzle biometrics along with breed, an estimated age from a dental photo with a confidence score, and a body condition score (1–5) from a side-profile photo. This is a supplementary identity and welfare record, not a replacement for a CVI, veterinary diagnosis, or any government-issued travel document — but it illustrates why permanent, tamper-resistant identification is worth pairing with paper or electronic health documentation for livestock that may travel or be exposed to disasters.

Common Mistakes to Avoid

• Waiting too long to schedule the exam — a CVI issued more than 30 days before travel is often rejected at the destination.
• Using a non-accredited veterinarian — a valid state veterinary license alone does not authorize CVI issuance.
• Assuming federal rules cover interstate pet travel — USDA APHIS confirms destination states set their own requirements, not the federal government.
• Confusing a CVI with an EU pet passport — they follow entirely separate legal frameworks and eligibility rules.
• Skipping confirmation of paper vs. electronic format — some states now require eCVIs only.

FAQ: CVI Health Certificate

What does CVI stand for?

CVI stands for Certificate of Veterinary Inspection, also commonly called a health certificate.

How long is a CVI health certificate valid?

Most CVIs are valid for 30 days from the veterinary exam date, though some states allow longer validity for specific species or circumstances, so always confirm with the destination state.

Who can issue a CVI?

Only a USDA-accredited veterinarian can issue a CVI, and they must hold the correct accreditation category (Category I or Category II) for the species being certified.

Do I need a CVI to fly with my pet domestically?

It depends on the destination state and the airline; USDA APHIS does not set interstate pet-travel rules itself, so requirements are determined by the receiving state or territory and, separately, by the airline's own policy.

Is a CVI the same as an EU pet passport?

No. A CVI is a U.S. veterinary inspection document valid for about 30 days, while an EU pet passport is a long-term document issued only to EU residents under European Commission regulations, recording microchip and rabies vaccination data.

Can I get an electronic CVI instead of paper?

Yes, in most states. Accredited veterinarians can issue electronic CVIs (eCVIs) through USDA's free VSPS system for livestock species, or through approved commercial platforms; some states now require the electronic format.

Does VSPS issue CVIs for dogs and cats?

No. USDA APHIS confirms that VSPS creates CVIs for livestock species such as bovine, equine, caprine, ovine, and porcine, but it does not currently provide CVIs for companion animals like cats and dogs.

What happens if I lose a CVI or an animal's physical ID tag?

A lost CVI or tag generally means re-examination and re-issuance by an accredited veterinarian, since the certificate itself is not proof of animal identity on its own; this is why some livestock owners supplement paper or electronic records with a separate, permanent identification method for their animals.

Bottom Line

A CVI health certificate is the standard, veterinarian-issued document U.S. animal owners need for interstate and much international animal movement, typically valid for 30 days and increasingly issued electronically. It is a health snapshot backed by USDA accreditation rules and state-specific requirements — not a government travel visa and not the same as the EU pet passport. As of August 2026, the shift toward electronic CVIs continues state by state, so confirm current format and validity requirements with your destination before you travel.
