THEDFORD prefixes in area code 308

NANPA records 6 assigned NXX blocks to rate center THEDFORD in area code 308, 1.3% of the 465 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. 2 holders hold those blocks, the largest being CONSOLIDATED TEL. CO. (5), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2021-06-16 and the most recent 2021-06-16. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
