How to read a Colorado hunt code.

Codes like EM059O1R look cryptic and aren't. Five parts, left to right — species, sex, unit, season, method — and once you can read one, you can read them all. Decode the exact hunt you're applying for so you never draw the wrong tag.

The quick answer

Species · sex · unit · season · method.

A Colorado hunt code packs an entire hunt into a few characters, read left to right: the species (E = elk), the sex (M = bull, F = cow, E = either-sex), the three-digit unit (059 = GMU 59), the season, and the method (R = rifle, A = archery, M = muzzleloader). So EM059O1Ris a bull elk, GMU 59, rifle tag for a specific season. Learn the five positions and every code becomes readable at a glance. Here’s each part.

Decoding EM059O1R

The five parts.

Species
E
The first letter is the animal: E for elk, D for deer, A for pronghorn (antelope), and so on. On an elk hunt code it's always E.
Sex / type
M
The second letter is what you can take: M for male (bull), F for female (antlerless/cow), or E for either-sex. This determines whether your tag is a bull tag, a cow tag, or either.
Unit (GMU)
059
The three digits are the Game Management Unit the tag is valid in — 059 for GMU 59. This is the geography of your hunt, and the single most important choice you make.
Season
O1
The next characters identify the season — which archery, muzzleloader, or rifle season the tag is for (for example, a code tied to 1st rifle vs 2nd rifle). The exact letters are set in the CPW brochure each year.
Method / weapon
R
The final letter is the weapon: R for rifle, A for archery, M for muzzleloader. It must match the season and the legal method for that hunt.

The exact season letters are defined in the current-year CPW big game brochure — use this guide for the structure, then confirm the specific codes there.

Frequently asked

Hunt-code questions.

How do you read a Colorado hunt code?

A Colorado hunt code is read in five parts, left to right: species (E for elk), sex or type (M male, F female, E either-sex), the three-digit Game Management Unit (e.g., 059), the season identifier, and the method or weapon (R rifle, A archery, M muzzleloader). So a code like EM059O1R reads as an elk, bull, GMU 59, a specific season, rifle tag. Decoding the code tells you exactly what you're applying for — the animal, the sex, the unit, the season, and the weapon — so you don't draw the wrong hunt.

What does EM059O1R mean?

Broken down: E = elk, M = male (bull), 059 = Game Management Unit 59, O1 = a specific season code, and R = rifle. Put together, it's a bull elk rifle tag valid in GMU 59 for that season. Every Colorado big game hunt code follows this same species-sex-unit-season-method pattern, so once you can read one, you can read them all. Always confirm the exact season letters against the current-year CPW brochure, since the season codes are defined there.

What do the letters in a Colorado hunt code mean?

Each position has a job: the first letter is the species (E = elk), the second is the sex or type (M = male/bull, F = female/cow, E = either-sex), the three digits are the GMU, the next characters are the season, and the last letter is the weapon (R = rifle, A = archery, M = muzzleloader). The codes are deliberately compact, so a single string like EF059E1A packs the whole hunt — species, sex, unit, season, weapon — into a few characters.

Why do hunt codes matter when applying?

Because the hunt code is exactly what you apply for — get a character wrong and you can draw a different sex, season, unit, or weapon than you intended, or waste your application. Knowing how to read a code lets you confirm you're entering the bull-vs-cow, season, and unit you actually want, and lets you compare codes intelligently when choosing your first, second, and third choices in the draw. It's a small skill that prevents an expensive mistake.

Where do I find the list of Colorado hunt codes?

The complete, current list of hunt codes — with the exact season letters, dates, tag quotas, and draw details — is published every year in the Colorado Parks and Wildlife big game brochure and in the online application system. Use this guide to understand the structure, then look up the specific codes for your unit and season in the official CPW materials before you apply, since the details are set fresh each year.
