# Colorado licences that expire in October — dora-co

> 90,352 active Colorado licences fall due for renewal in October, across 35 licence types.

## Licences that renew in October

DORA sets one expiry date per licence type, so renewals arrive in waves. 90,352 active licences expire in October, across 35 types.

### Why they all fall due together

Colorado does not renew licences on their anniversary. DORA sets a
**fixed expiry date per licence type** — and often a parity, odd
or even years — so every holder of that type renews on the same day. That is
why 90,352 licences share October.

It is in DORA's data, spread across a 344-row table of codes. Nobody
publishes it as a calendar, which is what this page is.
