EL CAMPO prefixes in area code 979
NANPA records 14 assigned NXX blocks to rate center EL CAMPO in area code 979, 3.4% of the 413 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 SOUTHWESTERN BELL (4), AERIAL COMMUNICATIONS, INC. (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2002-03-29 and the most recent 2025-04-07. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
