BASTROP prefixes in area code 737
NANPA records 19 assigned NXX blocks to rate center BASTROP in area code 737, 5.7% of the 333 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 T-MOBILE USA, INC. (7), FRACTEL, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2). The earliest assignment on record here is 2015-11-24 and the most recent 2026-07-21. 19 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 318, 512 – overlay codes cover the same geography, so a rate center is served by all of them.
