CROCKETT prefixes in area code 936

NANPA records 9 assigned NXX blocks to rate center CROCKETT in area code 936, 2.1% of the 422 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 VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2005-01-06 and the most recent 2021-07-26. 7 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 341, 510 – overlay codes cover the same geography, so a rate center is served by all of them.
