The 208 area code covers the entire state of Idaho, from Boise and the Treasure Valley to the northern Panhandle. One of the original area codes assigned in 1947, 208 served all of Idaho by itself for seventy years and now shares the state with the 986 overlay.

Geographic Coverage
The 208 area code is a statewide code covering all of Idaho, including the Boise metro cities of Boise, Meridian, Nampa, and Caldwell in the southwest, Twin Falls in the Magic Valley, Idaho Falls and Pocatello in the east, and Coeur d’Alene and Lewiston in the northern Panhandle. It borders Washington, Oregon, Nevada, Utah, Wyoming, Montana, and Canada.
Time Zone
The 208 area code spans two time zones, because the state of Idaho itself is split. Southern Idaho – including Boise, Meridian, Nampa, Twin Falls, Idaho Falls, and Pocatello, where the large majority of the population lives – observes Mountain Time (MT), following Mountain Standard Time (UTC−7) in winter and Mountain Daylight Time (UTC−6) in summer. The northern Panhandle – including Coeur d’Alene, Lewiston, Moscow, and Sandpoint – observes Pacific Time (PT), one hour behind. Both zones follow daylight saving time from mid-March through early November, so when calling a 208 number it helps to confirm whether the person is in southern (Mountain) or northern (Pacific) Idaho.
Tip: Business hours across the 208 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday – but remember that “local time” differs by an hour between southern and northern Idaho.
How to Dial a 208 Number
Because area code 208 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (208 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 208, followed by the seven-digit local number.
Scam Alerts for the 208 Area Code
Like every U.S. area code, 208 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Boise, Meridian, Nampa, Idaho Falls, Pocatello, Caldwell, Coeur d’Alene, Twin Falls should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Idaho Power reps demanding payment to avoid disconnection. |
| Bank Fraud Alerts | Robocalls impersonating your bank about “suspicious activity” to phish account details. |
| Grandparent Scam | A caller posing as a relative in trouble asking for emergency wire transfers. |
If you receive a suspicious call from a 208 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Idaho Attorney General’s Consumer Protection Division.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Idaho Power or Avista) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 208 caller making such a demand is a scammer.
History and Economy of the 208 Region
n
Area code 208 is one of the original 86 codes established in 1947, and it remains one of the last single-state area codes in the country – it covered all of Idaho on its own until the 986 overlay was added statewide in 2017. The regional economy is anchored by the Boise metropolitan area, home to Micron Technology’s semiconductor operations, HP, state government, and Boise State University. Agriculture is central to the state, from the famous Idaho potatoes and sugar beets to the dairy industry of the Magic Valley around Twin Falls. Idaho Falls hosts the Idaho National Laboratory, a major nuclear-research facility, while Pocatello, Lewiston, and the resort city of Coeur d’Alene anchor the eastern and northern regions.

Looking Up a 208 Number
n
To identify a 208 caller, use a reverse phone lookup service or search the full 10-digit number online. Many Idaho businesses, government offices, and healthcare providers list their 208 numbers publicly, so a quick search often confirms a legitimate caller. For unknown numbers, let the call go to voicemail – genuine callers usually leave a message.
