CLAYCENTER prefixes in area code 785

NANPA records 5 assigned NXX blocks to rate center CLAYCENTER in area code 785, 0.7% of the 726 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KS (1), LEVEL 3 COMMUNICATIONS, LLC - KS (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2004-01-16 and the most recent 2025-03-21. 5 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 402, 531 – overlay codes cover the same geography, so a rate center is served by all of them.
