PHARR prefixes in area code 956
NANPA records 33 assigned NXX blocks to rate center PHARR in area code 956, 4.5% 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. 10 holders hold those blocks, the largest being SOUTHWESTERN BELL (7), NEW CINGULAR WIRELESS PCS, LLC - IL (7), METROPCS, INC. (6). The earliest assignment on record here is 2002-09-25 and the most recent 2026-01-05. 29 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
