What is a Tequila NOM Number?

A tequila NOM number is the four-digit registration number of an authorized producer. Look for “NOM” and four digits on the bottle, usually on the back label. The number lets you look up the company and see which other brands are registered with it.

For example, NOM 1123 identifies Tequila Cascahuín, while NOM 1449 identifies Diageo México Comercializadora, the company listed for Don Julio. Enter a number in our tequila NOM list to find its producer, researched locations and associated brands.

Quick Facts About NOMs

• The four digits identify a registered producer. The full tequila standard has a different name: NOM-006-SCFI-2012.
• The CRT’s October 1, 2026 list contains 203 NOM numbers and 2,373 registered names. Our brand directory groups clear product variants and aliases into 2,226 entries.
• A producer can make several brands, and a brand can appear under more than one NOM. The number on a particular bottle helps you choose the relevant record.
• Producer locations help you explore where tequila is made. Information about an individual bottle’s agave, recipe and aging comes from its label and the producer’s account of that release.

The producer number and the tequila standard

NOMs in Mexico

NOM stands for Norma Oficial Mexicana, or Official Mexican Standard. Mexico uses these standards for many products and services. Tequila has its own standard covering production, bottling and labeling.

NOM for Tequila

NOM-006-SCFI-2012 sets out the rules for tequila. The Consejo Regulador del Tequila (CRT) inspects and certifies compliance. The four-digit number beside the NOM mark is the producer’s registration, rather than the number of the standard.

A registered company may operate more than one facility. The standard also allows production agreements between authorized producers, with oversight of the work and transfers. For “100% agave” tequila, bottling takes place in a plant controlled by the authorized producer within the denomination’s territory. The separate “Tequila” category can also be bottled by an approved bottler elsewhere.

Use the NOM to identify the company first. To trace a particular bottle to a facility or agave field, look for the producer’s release details. Our directory adds researched producer locations to the CRT company records.

How to look up a tequila NOM number

• Find “NOM” and the four digits on the bottle label.
• Enter the digits in the tequila NOM list. Open the result to see the company, locations and brands.
• If you have a name instead, search the tequila brand list. Open a brand to see its registered names and NOMs.
• Download the full directory or your filtered results as a Spirited Agave Excel workbook.

The directories identify the CRT edition being used. You can also consult the CRT’s brand register for its latest published list. If a search finds no match, try a shorter name or a different saved edition; older registrations and spelling differences can affect the result.

A Brand’s NOM Can Change Over Time

A brand can change producers as it grows, changes ownership or chooses a different production arrangement. Old and new bottles can remain on shelves together, and several producer registrations may appear in the same edition of the CRT list.

Kirkland Signature is a useful example. Older Silver bottles carried NOM 1142, La Madrileña. The current producer evidence reviewed for our Costco tequila guide points to NOM 1173, Santa Lucía, across the five Kirkland expressions. Both 1142 and 1173 remain in the October 2026 CRT register. Match an older review to the NOM on your bottle, as well as its expression name.

Casamigos appears under NOM 1416 and NOM 1609 in that same edition. The two company records are Productos Finos de Agave and Diageo México Operaciones. A list of registrations gives you the available matches; dated bottle labels and producer statements help explain which applies to a release.

How Many NOMs are There?

The CRT’s October 1, 2026 workbook contains 203 distinct NOM numbers and 2,373 registered names, including its two entries for authorized bottlers outside the appellation of origin. These are registration counts; one NOM may cover more than one production site.

Registered names include product lines and alternate spellings. For instance, Siete Leguas and 7 Leguas appear among the names associated with NOM 1120. Our 2,226-entry consumer directory groups clear variants while keeping the registered names available inside each result.

NOM 1438, Destiladora del Valle de Tequila, has the largest set in this edition: 249 registered names, grouped into 245 directory entries. Open NOM 1438 to explore them.

NOMs for Familiar Tequila Brands

These are the NOMs associated with the following brands in the October 1, 2026 CRT list. Where two numbers appear, the bottle’s label gives you the starting point for a specific tequila.

Do All Tequilas Have a NOM?

Yes. Bottled tequila must show the NOM mark and the authorized producer’s registration number. You will often find it beside the CRT letters. Other agave spirits may use different certifications and names, so start by checking whether the label actually says “Tequila.”

Do all Tequilas From the Same NOM Taste the Same?

No. Tequilas from the same producer can taste very different. A producer can make several recipes and ranges using different equipment, agave, fermentation and aging choices.

• Agave: its growing conditions and maturity affect the material the producer starts with.
• Cooking and extraction: a producer can use different ovens and extraction equipment for different products. Tahona and roller-mill extraction, for example, are distinct methods.
• Fermentation and distillation: yeast, fermentation vessels, the use of agave fibers and distillation choices all influence the spirit.
• Aging: oak type, previous barrel use, char and time in the barrel change flavor and texture.
• Finishing and formulation: filtration, bottling strength and permitted additives can further change the finished tequila. See our additive-free tequila guide for the separate question of additive evidence.

A shared NOM is a useful way to discover another brand to try. Compare the actual expressions and their production details when choosing bottles for a tasting.
