KAMAY prefixes in area code 940

NANPA records 4 assigned NXX blocks to rate center KAMAY in area code 940, 0.8% of the 506 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. 3 holders hold those blocks, the largest being VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (2), BANDWIDTH.COM CLEC, LLC - TX (1), SANTA ROSA TELEPHONE COOPERATIVE, INC. (1). The earliest assignment on record here is 2003-07-09 and the most recent 2025-11-20. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
