CORSICANA prefixes in area code 903
NANPA records 15 assigned NXX blocks to rate center CORSICANA in area code 903, 1.9% of the 771 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. 8 holders hold those blocks, the largest being SOUTHWESTERN BELL (5), LEVEL 3 COMMUNICATIONS, LLC - TX (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2002-03-29 and the most recent 2021-03-26. 12 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 430 – overlay codes cover the same geography, so a rate center is served by all of them.
