270 area code — Owensboro, KY geographic
Phone numbers beginning 270 are registered to the Owensboro area of Kentucky (Eastern and Central time zone). The code entered service on April 19, 1999. It is part of the 270/364 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 270 number can be used from anywhere — the code marks where the number was assigned.
767 central-office prefixes are currently active in this code, spread across 45 code-holding carriers. Thousands-block pooling applies to 597 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 170 distinct rate centers.
Practical takeaway: the 270 label narrows geography to Kentucky, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
270 was created from 502 in 1999. It has since spawned 364 (2014).
NANPA projects numbering capacity for the 270/364 complex to exhaust in 3Q 2109.
Unusually, 270 spans two time zones (Eastern and Central). When returning a call, check which part of Kentucky the prefix belongs to — the difference is a full hour.
Dialing: 10D locally, 10D to other codes (1+10 digit permissible at service providers discretion).
Worth noting: 270 is covers more rate centers (170) than any other Kentucky area code; it is also one of the few NANP area codes whose territory spans two time zones.

FAQ
Why do 364 and 270 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 270/364 complex shares one service area, and local calls are dialed with 10 digits.
Will 270 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2109 — decades of capacity remain.
Why am I getting spam calls from 270 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 270 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 270 number from?
270 is assigned to Owensboro and surrounding areas of Kentucky in the Eastern and Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 270 a toll-free number?
No. 270 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
