How to Read the USDA Establishment Number on a Meat Label
The EST. number inside the round USDA mark identifies the plant that processed your meat. How to decode the M, P, and V prefixes, find it on the package.
Key takeaways
- 01Every federally inspected meat, poultry, or egg product carries a USDA mark of inspection with an establishment number assigned to the plant where the product was processed (9 CFR 312.2 for meat, 9 CFR 381.96 for poultry).
- 02The prefix letter is the grant of inspection: M for meat, P for poultry, G for egg products, I for import inspection, V for voluntary inspection of non-amenable species such as bison.
- 03A suffix letter after the digits distinguishes two or more plants under the same ownership; a plus sign in the FSIS directory joins multiple grants at one location.
- 04The number tells you the plant, its city, and its state. It does not tell you the farm, and for ground beef it does not tell you which plants supplied the trim.
- 05The FSIS Meat, Poultry and Egg Product Inspection Directory is updated weekly; our registry at /processors carries the 1,495 federally inspected slaughter establishments from the September 1, 2026 pull.
- 06FSIS recall notices identify product by establishment number inside the mark, which makes the plant the most traceable fact on any package.

The number after EST. inside the round USDA mark identifies the one federally inspected plant where the product in your hand was last processed, and every one of the roughly 1,495 federally inspected slaughter establishments in our September 2026 registry has one. Read the prefix letter for the type of inspection, the digits for the plant, and any suffix letter for a sister facility, then look the number up in the FSIS directory or at /processors to get the plant's name and city. It is the only origin fact a label is required to carry.
01What the mark says
The federal inspection legend for meat is a circle with the words U.S. INSPECTED AND PASSED BY DEPARTMENT OF AGRICULTURE and the abbreviation EST. followed by the establishment number. The regulation that prescribes it is 9 CFR 312.2, and it also permits an abbreviated form of the same mark for small containers. Poultry carries a different legend under 9 CFR 381.96: a circle reading Inspected for Wholesomeness by U.S. Department of Agriculture with the letter P and the establishment number. Egg products use a third variant with a G number.
The mark is the plant's signature, applied under an FSIS inspector's supervision, and it may not be used by anyone who does not hold the grant of inspection it names. A package without the mark is either state-inspected (state marks look similar and carry the state's name), custom-exempt (stamped Not for Sale), or not meat at all.
02Decoding the number
An establishment number is a letter and a number. FSIS assigns a separate number for each grant of inspection a facility holds, and the letter tells you which grant.
Prefixes and modifiers in FSIS establishment numbers
| Element | Meaning | Example format | What it tells the shopper |
|---|---|---|---|
| M | Meat grant of inspection (cattle, hogs, sheep, goats, and other amenable livestock) | EST. 123 or M123 | A federally inspected meat plant; the digits identify it |
| P | Poultry grant of inspection | P-1234 or EST. P1234 | A federally inspected poultry plant |
| G | Egg products grant of inspection | G-12 | An egg products plant |
| I | Import inspection establishment | I-123 | A facility where imported product is reinspected on arrival; not a slaughterhouse |
| V | Voluntary inspection service: identification, export certification, or voluntary inspection of non-amenable species (bison, elk, deer, rabbit, and similar) | V-1234 | Bison and other exotic species are inspected under a V grant at the plant's expense |
| Suffix letter | Distinguishes two or more official establishments under the same ownership or control | EST. 123A | A sister plant of EST. 123, usually a different building or line |
| Plus sign (directory only) | Joins multiple grants held at one location | M123+P123 | One plant that slaughters both livestock and poultry |
On the package itself you will usually see only EST. and the digits inside the meat legend, or P and the digits inside the poultry legend. The M is implied for meat. Numbers are not sequential by state or region, and a low number is simply an old grant; the digits carry no information beyond identity. Glossary: establishment number, federally inspected.
03Where to find it on the package
Under 9 CFR 317.2(i) the establishment number must appear either within the official inspection legend or, if the plant prefers, elsewhere on the exterior of the container in a prominent and legible size with the prefix EST. It may also be placed off the exterior in a few defined cases: on the metal clip that closes a casing or bag, on the back of a paper label on a can, or on an aluminum tray inside the container, but only if a statement of its location is printed next to the legend.
Where to look, in order: the round mark on the principal display panel; the round mark on the back or side panel; a line reading EST. near the net weight or the safe-handling statement; the metal clip on a sausage or bag; the lid of a can. On a whole chicken the P number is usually inside the legend on the bag; on ground beef it is inside the legend near the safe-handling instructions. If a package of meat sold at retail has no establishment number anywhere, it was not processed under federal inspection.
04Look it up: the FSIS directory and our registry
FSIS publishes the Meat, Poultry and Egg Product Inspection Directory (the MPI Directory), a list of every establishment operating under a federal grant of inspection, with the plant name, street address, city, state, and phone number. It is updated weekly and posted as PDF and CSV files sorted by establishment name and by establishment number, and as a mobile app for Android and iOS. A companion file, the Establishment Demographic Data, adds each plant's size class, the species it slaughters, and its production categories, and is refreshed on the same schedule. FSIS also keeps a list of plants that surrendered their grant within the last three years, which is where a number goes when a plant closes.
Our registry is built from those two files. Every federally inspected establishment with a slaughter activity in the 50 states and the District of Columbia is listed at /processors, with a page for each state at /processors/[state] and a page for each plant. Type a number into the finder at /find to jump straight to the plant, or browse by state and species. The data vintage is printed on every registry page; the current pull is dated September 1, 2026 and covers 1,495 slaughter establishments.
State-inspected plants carry a state mark and a state number, and are listed by the state agency rather than FSIS. See state meat inspection programs for the 30 states that run one and /states for each state's rules.
05What the number tells you, and what it does not
It tells you the plant. The name, the city, the state, and, through the demographic file, whether the plant slaughters or only processes, which species it handles, and its size class (FSIS sorts plants into large, small, and very small by employee count). A plant listed as processing only did not kill the animal; it bought carcasses or boxed primals from a slaughter plant somewhere else.
It does not tell you the farm. A slaughter plant buys cattle from feedlots, sale barns, and direct from ranches, and the number is the same for all of them. It does not tell you where the animal was born, which is why the Product of USA claim exists as a separate, voluntary statement. It does not tell you how the animal was fed or raised. And for ground beef made at a grinding plant, it identifies the grinder, not the one or several slaughter plants that supplied the trim; FSIS traces those through the grinder's source records when it needs to.
It is the last link in the chain, not the first. Combined with a farm you can name, it closes the chain completely. On its own it locates the meat within a few hundred miles at most.
06Why the plant is the most traceable fact on the label
Three things make the establishment number more reliable than any other statement on the package.
First, it is mandatory. Product of USA, grass-fed, and every welfare logo are voluntary claims a packer chooses to make. The legend is required by 9 CFR 317.2 on every federally inspected package, and it is applied under the supervision of an inspector who is in the plant.
Second, it is the unit FSIS uses for enforcement. When FSIS issues a recall or public health alert, the notice identifies the product by the establishment number inside the USDA mark, along with lot codes and dates. The December 2025 ground beef recall for E. coli O26, for example, told consumers to look for EST 2083 on the packaging; a May 2025 alert cited EST. 4027 inside the mark. If you can read the number, you can check every recall against your freezer in a minute.
Third, it anchors the origin rule. Since January 1, 2026, a plant using the Product of USA claim must keep records proving birth, raising, slaughter, and processing in the United States and produce them for the inspector at that establishment. The claim lives at the plant, so verification does too.
07Worked examples
The formats below are illustrative. The numbers are chosen to show the pattern, not to identify particular companies; look any real number up before drawing a conclusion.
Reading establishment numbers (illustrative formats)
| What you see | How to read it | What to do next |
|---|---|---|
| Round mark, EST. 38 | A federal meat grant with a very old number; a long-established plant | Search 38 in the directory; check the demographic file for slaughter species and size |
| Round mark, EST. 18076 | A federal meat grant issued in the modern numbering range | Same lookup; a five-digit number is common for plants granted inspection since the 1990s |
| Round mark, P-7 | A federal poultry grant; a large legacy poultry plant | Search P7 in the directory by number |
| EST. 6789A | A sister facility of EST. 6789 under the same ownership | Both numbers appear in the directory with their own addresses |
| Directory entry M4561+P4561 | One location holding both a meat and a poultry grant | The package will show whichever legend matches the product |
| V-9876 on bison steaks | Voluntary inspection of a non-amenable species | The plant is federally inspected under a V grant; bison is not covered by mandatory inspection |
| Store label only, no round mark | Retail-exempt cutting; the legend was on the incoming box | Ask the counter for the box label or the packer's establishment number |
| Stamp reading Not for Sale, no EST. | Custom-exempt processing of an animal the customer owned | The plant is reviewed by FSIS or the state, not continuously inspected; see the custom-exempt guide |

08Special cases: state marks, imports, and custom-exempt
State-inspected meat carries a state legend rather than the federal one, with the state's name and a state establishment number. The Wholesome Meat Act of 1967 requires state programs to be at least equal to federal inspection, and 30 states run one in 2026. State-inspected product may be sold only within the state unless the plant is in the Cooperative Interstate Shipment program, in which case it carries a federal-style mark with the state abbreviation; see cooperative interstate shipment.
Imported meat is inspected on arrival at an I-numbered import establishment. If it is then cut or repackaged at a domestic plant, the package carries that domestic plant's M or P number, and nothing on the legend reveals the foreign origin. The foreign plant's own establishment number appears only on the shipping cartons. That is the gap the 2026 Product of USA rule addresses only for packers who choose to make the claim; see our import tracker.
Custom-exempt meat carries no establishment number at all, because the plant holds no grant of inspection. Packages are marked Not for Sale under 9 CFR 316.16 and belong to the person who owned the animal. Custom plants are reviewed periodically by FSIS or the state, generally once a year, rather than inspected daily.
Frequently asked questions
What does the EST number on meat mean?
It is the federal establishment number assigned to the plant where the product was processed under USDA inspection. It appears inside the round USDA mark of inspection, prefixed by EST. for meat or P for poultry, and can be looked up in the FSIS Meat, Poultry and Egg Product Inspection Directory or at /processors to find the plant's name and location.
How do I look up a USDA establishment number?
Search the FSIS Meat, Poultry and Egg Product Inspection Directory, which is updated weekly and available as a PDF, CSV, or mobile app, or type the number into our finder at /find. Both return the plant name, city, and state; our registry adds the species slaughtered and the plant's size class from the FSIS demographic file.
Does the establishment number tell me which farm the meat came from?
No. It identifies the plant, and a plant buys from many farms, feedlots, and sale barns. For ground beef it identifies the grinder, not the slaughter plants that supplied the trim. To know the farm, buy from one you can name; the establishment number then confirms which plant that farm uses.
What do the letters M, P, and V mean before an establishment number?
M is a meat grant of inspection, P is poultry, G is egg products, I is an import inspection facility, and V is voluntary inspection, used for non-amenable species such as bison, elk, and rabbit. A suffix letter after the digits marks a sister plant under the same ownership.
Where is the establishment number on a package of ground beef?
Inside the round USDA mark, usually printed near the safe-handling statement on the back or bottom of the tray. Under 9 CFR 317.2(i) it may instead appear elsewhere on the package with the prefix EST., or on a metal clip or interior tray if the label says where to find it.
Why does store-cut meat have no USDA mark?
Cutting and wrapping meat at a retail store is exempt from inspection, so the store applies its own label without a new legend. The establishment number belonged to the packer's box the primal arrived in. Ask the meat counter for the box label if you want the plant.
Do recalls use the establishment number?
Yes. Every FSIS recall and public health alert identifies affected product by the establishment number inside the USDA mark, together with lot codes and pack or use-by dates. Match the number first, then the dates.
