# Colorado licence types — dora-co

> The 204 licence types DORA issues, with how many active licences each holds.

## Every licence type

DORA issues 204 distinct licence types. 92 of them have a page here.

Checking more than one? [Bulk checks,
monitoring and API](/pro.md) — or take the register itself as a dataset,
with [published prices](/data.md).

A licence carries exactly one type, so these pages are disjoint and their
totals add up to the 597,451 active licences. The type also decides the
renewal date — see [the calendar](/renewal.md).

⚠️ 33,716 licences carry one of 6 codes that
DORA's type table does not translate — mostly advanced practice nurses and
prescribers. They appear under their raw code rather than an invented
label.
