How the 208/986 Area Code System Works

Area Code 208 vs 986: What's the Difference?

There is no functional difference between 208 and 986 phone numbers. Both area codes:

• Cover identical geographic areas (all of Idaho)
• Offer the same local calling features
• Work with all carriers and phone systems
• Require 10-digit dialing for all calls
• Have equal availability depending on carrier inventory

The 986 overlay was added in November 2016 to expand Idaho's phone number capacity without requiring existing 208 customers to change their numbers.

Technical Specifications

• Primary Area Code: 208 (established 1947)
• Overlay Code: 986 (implemented November 2016)
• Coverage: All of Idaho (83,569 square miles)
• Type: Statewide overlay system
• Combined Capacity: 15.6 million phone numbers
• Regulatory Authority: Idaho Public Utilities Commission (IPUC)

How to Dial Idaho Phone Numbers: 10-Digit Dialing Rules

Implementation Timeline:

• November 5, 2016: Permissive dialing period began
• August 5, 2017: 10-digit dialing became mandatory statewide

Dialing Requirements:

• All calls within Idaho require area code + 7-digit number
• Long-distance calls continue to require 1 + area code + number
• Emergency services (911) remain 3-digit dialing
• Service numbers (211, 311, 511, 811) remain 3-digit where available
• Operator services (411, 611, 711) remain 3-digit dialing

Number Portability:

• Simple ports (single line) complete within 1 business day; wireless-to-wireless transfers typically take 2–3 hours
• Non-simple ports (multiple lines or complex configurations) complete within 4 business days for wireline or intermodal transfers
• Requires account number, PIN, and billing address from current provider
• Do not cancel existing service until port completes to avoid losing your number

Historical Development and Evolution

Timeline of Major Changes

• 1947: Area code 208 established as one of original 86 NANP area codes
• 2001: NANPA projects number exhaustion by 2003
• 2002: Number pooling implemented in Boise to conserve numbers
• 2007: Statewide number pooling extended life of 208
• 2013: Revised exhaustion projection moved to 2018
• November 2015: IPUC approves 986 overlay implementation
• November 5, 2016: Area code 986 becomes active; permissive 10-digit dialing period begins
• August 5, 2017: 10-digit dialing becomes mandatory statewide
• September 5, 2017: New telephone lines may be assigned numbers using 986 area code
• 2020: CenturyLink rebrands enterprise services as Lumen Technologies
• July 2024: Idaho population reaches 2,001,619 (U.S. Census Bureau)
• May 21, 2025: AT&T announces acquisition of Lumen's Mass Markets fiber business (Quantum Fiber) for $5.75 billion
• Expected 2026: AT&T-Lumen transaction close (pending regulatory approval)

Why an Overlay Was Necessary

Idaho's unique position as one of few states with a single area code became unsustainable due to:

• Population Growth: Reached 2,001,619 residents in 2024 with 1.5% annual growth (ranked 7th nationally); net migration accounts for 74.1% of growth since 2020
• Technology Proliferation: Multiple devices per person requiring numbers
• Business Expansion: Growing tech industry and economic development
• Rural Communication Needs: Extending service to previously unserved areas

The overlay approach preserved existing numbers while providing capacity for future growth without requiring customers to change their established phone numbers.

Historical Exhaustion Forecasts:

• 2001: NANPA projected 208 would exhaust by 2003
• 2013: Revised projection moved exhaustion to 2018
• 2015: IPUC approved 986 overlay to prevent exhaustion
• Current Status (2025): Area code 208/986 is not in jeopardy; no relief planning underway (source: NANPA Area Code Relief Planning reports)

However, the IPUC retains authority under Idaho Code § 61-622 over service quality standards, billing practices, tariff approvals, and customer relations for all providers of basic local exchange service.

Federal Compliance

Idaho telecommunications operate under:

• North American Numbering Plan Administration (NANPA) guidelines
