Idaho's Statewide Overlay: What the 986 Area Code Covers

Introduction

If you've seen a call or text come in from a 986 number, it's from Idaho — the whole state, not just one city. The 986 area code is a statewide overlay that shares the exact same territory as Idaho's original area code, 208, and it's just as ready for a full UCaaS business phone system as 208 is. This guide explains where 986 is located, what an overlay actually means for dialing, which time zone it falls in, its history, and how to get a 986 number of your own.

Quick Facts: 986 Area Code

Where Is the 986 Area Code Located?

986 covers all of Idaho — it isn't tied to one city or region the way most area codes are. Because it's an overlay rather than a split, 986 and 208 code cover identical geography; the only difference is which numbers get assigned which code going forward.

That means 986 numbers can belong to callers anywhere in the state: Boise and its suburbs of Meridian and Nampa in the southwest, Idaho Falls and Pocatello in the southeast, Twin Falls in the south-central Magic Valley, Coeur d'Alene and Moscow up in the northern panhandle, or Lewiston and Rexburg further out. A 986 number tells you the caller has an Idaho line — not which part of the state they're in.

What Time Zone Is the 986 Area Code In?

This is where Idaho gets a little unusual: the state is split across two time zones, and both fall under the 986/208 overlay. Most of Idaho, including Boise, Idaho Falls, Pocatello, and Twin Falls, runs on Mountain Time (MT). The northern panhandle — Coeur d'Alene, Sandpoint, and Moscow — runs on Pacific Time (PT), an hour behind the rest of the state. A 986 number alone won't tell you which zone the caller is in; the city does.

History of the 986 Area Code

Area code 208 has covered Idaho since 1947, when it was one of the original 86 area codes assigned across North America. It held that role alone for seventy years. By the early 2000s, growth in landlines, cell phones, and pagers put pressure on the 208 numbering pool. The Idaho Public Utilities Commission (IPUC) delayed the need for a new code for over a decade through number pooling, first in Boise in 2002, then statewide in 2007.

By 2013, projections showed 208 would run out of available numbers by 2018, and all conservation options had been used. Rather than split the state geographically — which would have forced some residents to change their area code and reprogram devices — the IPUC opted for a statewide overlay, following the model West Virginia used with 304/681 in 2009.

The IPUC approved the 986 overlay on November 2, 2015. It officially entered service on November 5, 2016, starting a permissive dialing period where both 7- and 10-digit dialing worked. Mandatory 10-digit dialing took effect across Idaho on August 5, 2017, and has applied to all local calls ever since.

Is 986 an Overlay Area Code?

Yes. 986 is an overlay, not a split. In a split, a state or region is divided geographically and some residents are assigned a new area code while others keep the old one. In an overlay, the new area code is layered on top of the same region, and every existing subscriber keeps their original number. New lines and numbers activated after November 2016 may be issued a 986 number, while older Idaho numbers remain on 208 — both codes now serve every part of the state equally.

How to Dial a 986 or 208 Number

Because Idaho requires 10-digit dialing, every local call needs the area code included — even calls between two Idaho numbers in the same town. To call an Idaho number from anywhere in the US or Canada, dial 1, then the area code (986 or 208), then the 7-digit number. Skipping the area code will no longer connect the call, regardless of which code the recipient has. Providers like Ajoxi issue a 986 number already configured for correct 10-digit dialing.

Calls From a 986 Area Code: Are They Scams?

A 986 number by itself doesn't tell you much about who's calling — it just means the line was issued after Idaho's 2016 overlay went live. Most calls from a 986 area code are perfectly ordinary: Idaho businesses, healthcare providers, schools, and residents using newer lines. But because 986 is still a relatively new and less recognized code, scammers do spoof it deliberately — a caller ID showing a 986 number doesn't confirm the call is actually originating in Idaho, or that the caller is who they claim to be.

If you're getting repeated or unexpected calls from a 986 area code, especially ones asking for payment, banking details, or account verification, treat them like any unfamiliar number: don't share sensitive information on the spot, hang up and call the organization back on a verified number, and consider blocking the caller if it continues.

Are 986 area code text messages a scam? Not automatically — legitimate businesses do send appointment reminders, order updates, and verification codes from 986 numbers, the same way they would from any other area code. The same rule applies to texts as calls: don't click links or share personal or payment information from an unsolicited 986 text unless you can verify the sender independently. Report persistent spam texts to your carrier by forwarding them to the FCC's designated short code, 7726.
