# Colorado licence datasets — dora-co

> DORA's licensing file, deduplicated on the real key, joined to the licence-type table, with the renewal calendar attached.

## The register, prepared

Everything on this site is free to read. What is sold is the work of finding the real key, joining the type table, and attaching the renewal calendar.

The pages of this site are free and will stay free : **an official fact belongs to no one**. What is sold here is the compilation work — extracting DORA's Colorado professional licensing file, reconciling it, dating it, and delivering it in a usable form.

### What is actually added

- **The real key.** `licensenumber` is not unique — it is
sequential within a licence type. 602,958 rows contain 349,844 distinct numbers
but **597,451 distinct licences**. Anyone joining on the number
alone merges strangers.
- **The type table, joined.** The main file says `RN`
and `COS`; the labels live in a second dataset. 198 codes of 204
translate — and we say which ones do not rather than invent a label.
- **The renewal calendar.** Cycle, year parity and expiry date
per type, which is what makes a whole profession fall due together.
- **The duplicates removed.** 5,483 rows are exact repeats.

### The flow is the product

DORA republishes the register rather than reporting what changed. A snapshot
tells you today; only a sequence tells you who lapsed. We keep every collection
from 2026-08-20 on and deliver the differences.

- **Change feed — USD 300 / month**Or USD 3 000 a year. At every collection, what came in, went out or changed since the previous one. This is the part that does not age.
- **One slice — USD 90 / month**The feed restricted to a single profession or city, for those who do not need the rest.
- **Full snapshot — USD 4 000, once**The state of the register on the day of delivery, every field included. Listed last on purpose : a snapshot ages.

### What you get, field by field

*Fields delivered and fill rate, measured on the rows actually delivered — not estimated*

| Field | Description | Filled |
|---|---|---|
| `licence_key` | ⚠️ TYPE-number — the only key that identifies a licence, because the number alone does not. | 100.0 % |
| `licence_number` | As DORA prints it. | 100.0 % |
| `name` | ⚠️ Assembled from first/middle/last/suffix or the entity name, which are never all filled at once. | 100.0 % |
| `licence_type` | ⚠️ The plain-English label, joined from DORA's type table. | 94.4 % |
| `category` | ⚠️ The family. | 94.4 % |
| `renewal_cycle / parity / expiry_date` | ⚠️ The renewal calendar for the type — the reason a whole profession renews the same day. | 94.4 % |
| `city / state` | The city. The postcode is in the source and is not republished on any page. | 99.9 % |
| `first_issued / last_renewed / expires` | ⚠️ Normalised to ISO dates. | 99.9 % |
| `disciplinary_action_count` | ⚠️ How many actions are on the licence. | 100.0 % |
| `disciplinary_actions` | ⚠️ Action type, case number and dates — supplied for compliance use, not for publication. | 2.3 % |
| `is_business` | ⚠️ Entity or individual. | 100.0 % |
| `active_only` | ⚠️ 597,451 active licences reconciled from 602,958 rows — 5,483 exact duplicates removed. | 100.0 % |

The 10 fields marked ⚠️ **do not exist in the source** : we add them — a join, a normalisation, or a reconstructed history. That is the part a buyer cannot reproduce by downloading the official file.
