KATY prefixes in area code 281

NANPA records 16 assigned NXX blocks to rate center KATY in area code 281, 2.0% of the 786 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. 4 holders hold those blocks, the largest being CONSOLIDATED COMMUNICATIONS OF TEXAS COMPANY (13), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (1), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (1). The earliest assignment on record here is 2003-10-21 and the most recent 2019-02-08. 13 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 346, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
