Why Metro Meridian Has 2 Area Codes
When a region uses more numbers than one code can hold, new codes are overlaid on the same territory rather than forcing anyone to change numbers. Metro Meridian now uses 208 and 986: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.

How Idaho Got Its Codes
Every Idaho area code, in the order it entered service. Splits carved new regions; added codes overlay existing ones, which is why ten-digit dialing is standard.
| In service | Code | How it arrived |
|---|---|---|
| 1947 | 208 | One of the original area codes of 1947 |
| 2017 | 986 | Added to the 208 region |
