# Colorado licences that expire in September — dora-co

> 119,568 active Colorado licences fall due for renewal in September, across 8 licence types.

## Licences that renew in September

DORA sets one expiry date per licence type, so renewals arrive in waves. 119,568 active licences expire in September, across 8 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 119,568 licences share September.

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.
