986 Area Code: Idaho's Statewide Overlay Number

The 986 area code is Idaho's second telephone code — not a new region, but a second layer of numbers spread across the exact same territory as the state's original 208 code. It reaches Boise and the Treasure Valley, Idaho Falls and Pocatello in the east, Coeur d'Alene in the northern Panhandle, and every other Idaho city and town in between.

986 went into service in November 2016 as a statewide overlay, added on top of 208 rather than carved out of it, so no existing resident had to change their number.

Most people looking up 986 fall into two groups: those assigned a 986 number who want to understand what the code represents, and those who received a call from a 986 number and want to know whether it is a genuine Idaho line or a spoofed one.

This guide explains what 986 is, the statewide territory it shares with 208, how the overlay came about and why it makes 986 only the second of its kind nationally, Idaho's two time zones, the Gem State economy, common scam patterns, and how to activate a 986 virtual number for a business.

The 986 area code is a telephone code that covers the entire state of Idaho, layered directly over the original 208 code as an all-services overlay. It carries no geographic meaning of its own beyond "Idaho" — a 986 number and a 208 number can belong to next-door neighbors in the same Boise subdivision.

The Idaho Public Utilities Commission approved 986 on November 2, 2015, and the code went live on November 5, 2016. New lines assigned statewide after that date could receive either 208 or 986, while every number already in service kept its original 208 code unchanged.

Dialing Format and Time Zone

Because 986 overlays 208 across the same ground, Idaho now requires ten-digit dialing for every local call, a rule that took full effect on August 5, 2017. Anyone unfamiliar with the standard format can review the US phone number format before dialing.

• Dialing format: (986) 555-0132
• International: +1 986-555-0132
• Overlay of: 208, Idaho's original 1947 area code
• Ten-digit dialing is mandatory statewide, including local calls between two Idaho numbers

The 986 footprint is the entire state of Idaho — the same territory as 208, with no internal boundary between the two codes. Boise anchors the region as the state capital, Idaho's largest city, and the seat of Ada County in the fast-growing Treasure Valley.

Boise & the Treasure Valley

• Boise — the state capital and largest city, the natural hub of any statewide Idaho code
• Nampa & Meridian — the Treasure Valley's largest and fastest-growing suburban cities
• Caldwell — a Treasure Valley city anchoring the western edge of Ada and Canyon counties

The Rest of the Gem State

• Idaho Falls — the hub of eastern Idaho near the Wyoming border and the Snake River Plain
• Pocatello — a southeastern Idaho city and home to Idaho State University
• Twin Falls — the center of the Magic Valley region along the Snake River Canyon
• Coeur d'Alene — the resort city on Lake Coeur d'Alene in the northern Panhandle

Because 986 shares its footprint exactly with the 208 area code, the two are best understood together — anyone comparing the state's original code to its overlay can see the full picture side by side.

Idaho held onto a single area code longer than almost any other state. The 208 code had covered the entire territory since the North American Numbering Plan was first laid out in 1947, and it stayed that way for nearly seventy years while most other original codes elsewhere split into two or more regions.

Why an Overlay Instead of a Split

By the mid-2010s, regulators projected that Idaho's remaining supply of 208 numbers would run out within a few years, driven by population growth and demand from wireless devices, businesses and internet services. Rather than draw a new line through the state and force some residents to adopt a different code, the Idaho Public Utilities Commission chose an overlay: a second code, 986, spread across the identical territory.

• November 2, 2015 — the Idaho PUC approves the 986 overlay for the entire state
• November 5, 2016 — 986 officially goes into service statewide
• August 5, 2017 — ten-digit dialing becomes mandatory for every local Idaho call

That decision made 986 only the second statewide overlay in the history of the North American Numbering Plan, following West Virginia's adoption of the same approach with its 304 and 681 codes in 2009. Both states share a common trait: a single area code covering the entire state, growing population, and regulators unwilling to force a wholesale renumbering.

The result is that every existing 208 number stayed exactly the same, while new lines issued after 2016 could be assigned either code — meaning a business calling itself "local Boise" might legitimately carry a 986 number rather than the more familiar 208.

Idaho does not split time zones the way many people assume — the state is not divided cleanly down the middle, and only a small slice of the north actually falls outside Mountain Time. Most of Idaho, including Boise, Idaho Falls, Pocatello and Twin Falls, observes Mountain Time.

• Pacific Time (PT) — five northern Panhandle counties: Boundary, Bonner, Kootenai, Benewah and Shoshone
• Mountain Time (MT) — the rest of the state, including Boise, Idaho Falls, Pocatello, Twin Falls and Coeur d'Alene's neighboring Panhandle counties farther south
• The boundary runs roughly along the Salmon River and Hells Canyon, not a straight north-south line

A 986 or 208 number could belong to either time zone, so a business running a statewide line should plan its calling hours around both — a schedule tuned only to Boise's Mountain Time will land an hour early for callers in the five Pacific Time Panhandle counties.

A 986 number connects a business to an economy built on agriculture, semiconductors and outdoor tourism. Idaho remains one of the country's leading potato producers, and wheat, dairy and cattle farming still anchor much of the Snake River Plain around Twin Falls and Idaho Falls.

Micron and the Treasure Valley

Boise is also home to Micron Technology, a semiconductor and memory manufacturer founded there in 1978 and still headquartered in the city today. Micron ranks among Idaho's largest private employers and one of the world's top memory-chip makers, anchoring a growing technology sector across the Treasure Valley.

Tourism and the Outdoors

North and central Idaho draw visitors to Lake Coeur d'Alene, Sun Valley and vast public wilderness, while the Magic Valley around Twin Falls and the Snake River Canyon support both farming and recreation. A 986 number reads as authentically Idahoan across all of it, from a Boise tech firm to a Panhandle outfitter.

986 is a legitimate, officially assigned Idaho code, but like any area code its numbers can be spoofed. Caller-ID spoofing lets a fraudster display any number — including a 986 prefix — on a recipient's screen, so a call can appear to come from a local Boise business or state agency when it does not.

• Unsolicited calls demanding immediate payment by gift card, wire transfer or cryptocurrency
• Callers posing as a utility, bank or state agency asking to "verify" personal or account details
• Fake warnings about an unpaid toll, tax bill or benefit problem that pressure an urgent callback
• Robocalls offering a prize or refund that require sharing card details to "process" it

Federal rules on caller-ID and numbering provisions govern how carriers assign and protect numbers like 986, and the safest habit is still to verify independently before acting on any unexpected call rather than trusting the name or number displayed on a screen.

Modern cloud phone providers let a business activate a 986 number in minutes — no Boise office, no hardware, and no long-term contract. Search available 986 numbers, complete a short verification, and route the line to any device anywhere in the world.

A 986 number suits any business targeting Idaho customers statewide — agricultural suppliers on the Snake River Plain, technology companies expanding into the Boise market alongside Micron, and hospitality or outfitting operators in the Panhandle and central mountains. A company comparing 986 to Idaho's original 208 area code can pick either freely, since both cover identical ground.

MeraTalk provides 986 numbers as part of its cloud telephony platform — lines activate in minutes, route to any device, and pair with voicemail, call recording, an auto-attendant and CRM integration from one dashboard. A business that already runs a virtual phone number elsewhere can add a 986 line as a second local number in the same account. To get started, search available numbers at meratalk.com.
