Area codes serving Eau Claire
Eau Claire sits in Wisconsin, part of the Midwest region and the Central Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 534, 715.
The original code is 715. As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.
How to pick an area code for a new number
When you activate a new line in Eau Claire, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 715), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
Dialing in Eau Claire
Because Eau Claire is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in Wisconsin, visit the Wisconsin area codes page.
