Area code history

Originally, there were two area codes for this area: 0040 for Lewis and 0041 for Great Bernera. In 1968 these codes were changed to 0850 and 0851 respectively, as part of a nationwide plan to free up numbers starting 00 for other purposes.

At some point around 1985, the separate 0850 code for Lewis was withdrawn and all numbers were transferred into the 0851 code. This then eventually became 01851, following a renumbering programme that took place across the UK during April 1995.
