WESLACO prefixes in area code 956
NANPA records 36 assigned NXX blocks to rate center WESLACO in area code 956, 4.9% of the 735 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (11), STPCS JOINT VENTURE, LLC (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (5). The earliest assignment on record here is 2001-09-10 and the most recent 2026-02-05. 34 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
