CLEBURNE prefixes in area code 817

NANPA records 18 assigned NXX blocks to rate center CLEBURNE in area code 817, 2.3% of the 781 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. 7 holders hold those blocks, the largest being SOUTHWESTERN BELL (9), NEW CINGULAR WIRELESS PCS, LLC - IL (3), PATHWAY COM-TEL, INC. - TX (2). The earliest assignment on record here is 2001-04-18 and the most recent 2010-07-26. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 682 – overlay codes cover the same geography, so a rate center is served by all of them.
