WALNUT RDG prefixes in area code 870

NANPA records 5 assigned NXX blocks to rate center WALNUT RDG in area code 870, 0.6% of the 785 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 (2), E. RITTER COMMUNICATIONS, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-05-08 and the most recent 2001-05-08. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
