BERESFORD prefixes in area code 605

NANPA records 4 assigned NXX blocks to rate center BERESFORD in area code 605, 0.5% of the 745 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 (1), METROPCS, INC. (1), BERESFORD MUNICIPAL TEL. CO. (1). The earliest assignment on record here is 2003-08-07 and the most recent 2003-08-07. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
