Area code history

Kilchrenan's original area code was 0025. This lasted until 1968 when the code was changed to 0866, as part of a nationwide plan to free up numbers starting 00 for other purposes.

The 0866 code eventually became 01866, following a renumbering programme that took place across the UK during April 1995.
