715 is the area code for Eau Claire, Wisconsin, in service since January 1, 1947, Central time. It is part of the 534/715 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 715 number can be used from anywhere — the code marks where the number was assigned.

784 central-office prefixes are currently active in this code, spread across 83 code-holding carriers. Thousands-block pooling applies to 592 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 253 distinct rate centers.

It has since spawned 534 (2010).

FAQ

Will 715 run out of numbers?

NANPA's current forecast projects exhaust in 4Q 2070 — decades of capacity remain.

Why am I getting spam calls from 715 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 715 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 715 number from?

715 is assigned to Eau Claire and surrounding areas of Wisconsin in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 715 a toll-free number?

No. 715 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Why do 534 and 715 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 534/715 complex shares one service area, and local calls are dialed with 10 digits.
