HARLINGEN prefixes in area code 956
NANPA records 86 assigned NXX blocks to rate center HARLINGEN in area code 956, 11.7% 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. 27 holders hold those blocks, the largest being STPCS JOINT VENTURE, LLC (24), SOUTHWESTERN BELL (22), NEW CINGULAR WIRELESS PCS, LLC - IL (8). The earliest assignment on record here is 2001-02-02 and the most recent 2024-11-06. 69 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
