Geographic Coverage
The 606 area code covers eastern Kentucky, from Ashland on the Ohio River in the northeast, through the Appalachian coalfield cities of Pikeville, Hazard, and Middlesboro, to the south-central hubs of Somerset, London, and Corbin along Interstate 75, and Morehead to the northwest. It borders West Virginia, Virginia, and Tennessee across the mountains.
Time Zone
The 606 area code observes Eastern Time (ET). Clocks follow Eastern Standard Time (UTC−5) in winter and shift to Eastern Daylight Time (UTC−4) from mid-March through early November. Kentucky is split between two time zones, and the 606 region lies in the Eastern zone, one hour ahead of western Kentucky. From the West Coast, this area is three hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 606 number at 12:00 PM local time.
Tip: Business hours across the 606 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 606 Number
Area code 606 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (606 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 606, followed by the seven-digit local number.
Scam Alerts for the 606 Area Code
Like every U.S. area code, 606 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Ashland, Pikeville, Somerset, London, Middlesboro, Hazard, Corbin, Morehead 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 Kentucky Power callers demanding instant payment to keep your power on. |
| Disability / Benefits Scam | Calls posing as the Social Security Administration threatening to cut off benefit payments. |
| Medicare / Health Scam | Robocalls seeking Medicare numbers under the guise of free braces or test kits. |
If you receive a suspicious call from a 606 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 Kentucky Attorney General’s Office.
- 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 (LG&E, Kentucky Utilities, or Kentucky Power) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 606 caller making such a demand is a scammer.
History and Economy of the 606 Region
n
Area code 606 was created in 1954, split from 502, to serve eastern Kentucky; in 2000 the central and northern part of its territory was carved out into the 859 area code, leaving 606 focused on Appalachia. The regional economy has historically been rooted in coal mining across the eastern coalfield, and although coal has declined, it remains significant in the mountain counties. Ashland anchors the northeast with a heritage of steel and oil refining along the Ohio River, Pikeville has grown as a regional healthcare and education center, and tourism is increasingly important – the Daniel Boone National Forest, Cumberland Falls, and the Red River Gorge draw visitors from across the region.
