HEBBRONVL prefixes in area code 361

NANPA records 5 assigned NXX blocks to rate center HEBBRONVL in area code 361, 0.9% of the 538 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), STPCS JOINT VENTURE, LLC (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2003-02-20 and the most recent 2025-01-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
