DECATUR prefixes in area code 940

NANPA records 15 assigned NXX blocks to rate center DECATUR in area code 940, 3.0% of the 506 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 NEW CINGULAR WIRELESS PCS, LLC - IL (3), BRIGHTSPEED OF TEXAS, INC. (3), METROPCS, INC. (2). The earliest assignment on record here is 2001-05-29 and the most recent 2023-12-22. 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 codes 217, 256, 260, 269 – overlay codes cover the same geography, so a rate center is served by all of them.
