Idaho has 2 active area codes as of 2026, covering the state through a mix of original 1947 assignments, geographic splits, and modern overlays. This guide walks through the full list, which regions each code serves, the order they came online, and where new codes are most likely to land next.
The Short Answer
Idaho currently has 2 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Idaho ranks #38 nationally with roughly 2,001,619 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Full List of Idaho Area Codes
The active area codes serving Idaho are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 208 — Entire state of Idaho, including Boise, Nampa, Meridian, Idaho Falls, Pocatello, Coeur d'Alene (one of the original 1947 area codes)
- 986 — Entire state of Idaho (same geographic area as 208) (overlay of 208)
How Idaho’s Area Codes Grew Over Time
Idaho received its first area code, 208, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

Browse Idaho Area Codes →- 1947 — Area code 208 was assigned to Idaho as one of the original North American area codes, covering the entire state.
- 2001 — NANPA projected that area code 208 would exhaust its number supply by 2003, prompting relief planning.
- 2002 — The Idaho Public Utilities Commission adopted number conservation measures that delayed the need for a second area code for years.
- 2015 — On November 2, the Idaho PUC approved adding 986 as a statewide overlay of 208 rather than a geographic split.
- 2016 — On November 5, area code 986 entered service and a permissive dialing period began, allowing 7 or 10 digit dialing.
- 2017 — Ten-digit dialing became mandatory across Idaho on August 5, and new numbers in 986 began being assigned on September 5, ending Idaho's 70-year single-code era.
What’s Next for Idaho Area Codes
Idaho is not on NANPA’s near-term relief list, and neither 208 nor 986 appears among the NPAs projected to exhaust within the next 36 months in NANPA’s most recent NRUF and NPA exhaust analysis. The 2017 statewide overlay added roughly 7.9 million additional numbers to a state of about 2 million people, and number pooling has further extended the supply, so no new Idaho area code is currently planned.
Frequently Asked Questions
How many area codes does Idaho have right now?
Idaho has 2 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Idaho?
208 is the oldest active area code in Idaho, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Idaho?
The most recent area code addition to Idaho was 986, activated in 2017. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Idaho need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
How many area codes does Idaho have?
Idaho has 2 active area codes: 208 and 986. Both cover the entire state as an overlay, so a phone number’s area code does not tell you which part of Idaho it is from.
Do you have to dial 10 digits in Idaho?
Yes. Because 208 and 986 overlay the same area, 10-digit dialing (area code plus the 7-digit number) has been mandatory statewide since August 5, 2017, even for local calls.
Is 986 a real Idaho area code?
Yes. Area code 986 entered service on September 5, 2017 as an overlay of 208 and is assigned to new lines across Idaho. You can read more about how area codes work.
Which area code is older, 208 or 986?
208 is the original, assigned in 1947 as one of the first area codes in North America. It was Idaho’s only area code for 70 years until 986 was added in 2017.
