How to Dial 859 Area Code: 10-Digit Dialing Requirements

Use these standard dialing formats for calls within or to area code 859:

Remember: Always dial 10 digits for all calls within area code 859, whether local or long distance. Dialing only 7 digits will fail, and you'll hear a recorded message instructing you to hang up and redial with the area code.

10-Digit Dialing Timeline:

• April 24, 2021: Permissive dialing period began (both 7-digit and 10-digit dialing worked)
• October 24, 2021: Mandatory 10-digit dialing implemented for all calls in area code 859
• July 16, 2022: 988 Suicide & Crisis Lifeline launched nationally

Area code 859 was one of 82 area codes requiring this transition because some phone numbers in the region begin with the 988 exchange. Without 10-digit dialing, calling a local 988 number would connect you to the crisis hotline instead. The FCC mandated this change to accommodate the nationwide 988 designation for the National Suicide Prevention Lifeline and ensure public safety.

Important: Emergency services remain unchanged. Dial 911 for emergencies using just 3 digits. The 988 crisis hotline also uses 3-digit dialing. Dialing 988 from area code 859 connects you to the 988 Suicide & Crisis Lifeline, providing 24/7 access to trained crisis counselors. The original 10-digit number (1-800-273-8255) remains operational and routes to 988 indefinitely.

Mobile carriers: Major carriers (Verizon, AT&T, T-Mobile) provide 859 numbers for mobile service. Availability depends on number inventory.

Number portability: The Telecommunications Act of 1996 lets you transfer your existing 859 number between carriers (landline to mobile, mobile to VoIP) while keeping the same number.

859 Area Code History: The 1999 Split from 606

Area code 859 split from area code 606 in 1999 and went into service on April 1, 2000. The split deviated from standard practice – instead of assigning the original area code to the largest city, the Kentucky Public Service Commission and BellSouth (now part of AT&T) assigned 606 to the less populated, economically disadvantaged eastern Kentucky counties despite Lexington being the largest city in the old 606 territory.

This decision minimized the financial burden of switching to a new area code for these communities. The rural 606 region is one of the nation's poorest – 16 of the 100 poorest U.S. counties by median income are located in the 606 area code region.

Interesting Detail: On an alpha-numeric telephone keypad, 859 spells UKY, a nod to the University of Kentucky in Lexington, the area code's largest city.
