HILLSBORO prefixes in area code 254
NANPA records 17 assigned NXX blocks to rate center HILLSBORO in area code 254, 2.5% of the 672 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. 10 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), LEVEL 3 COMMUNICATIONS, LLC - TX (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-02-12 and the most recent 2021-04-26. 15 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 codes 217, 304, 319, 326 – overlay codes cover the same geography, so a rate center is served by all of them.
