EAU CLAIRE prefixes in area code 534
NANPA records 8 assigned NXX blocks to rate center EAU CLAIRE in area code 534, 8.2% of the 98 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 8 holders hold those blocks, the largest being CSC WIRELESS, LLC (1), BOOST SUBSCRIBERCO L.L.C. (1), PEERLESS NETWORK OF WISCONSIN, LLC - WI (1). The earliest assignment on record here is 2018-11-19 and the most recent 2026-06-04. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 269, 715, 724 – overlay codes cover the same geography, so a rate center is served by all of them.
