HEALDTON prefixes in area code 580

NANPA records 4 assigned NXX blocks to rate center HEALDTON in area code 580, 0.5% of the 741 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 SOUTHWESTERN BELL (1), UNITED STATES CELLULAR - OK (1), METROPCS, INC. (1). The earliest assignment on record here is 2001-05-02 and the most recent 2025-03-27. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
