CENTERTOWN prefixes in area code 573

NANPA records 3 assigned NXX blocks to rate center CENTERTOWN in area code 573, 0.4% of the 786 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. 3 holders hold those blocks, the largest being METROPCS, INC. (1), EMBARQ MISSOURI, INC. DBA CENTURYLINK - MO (1), CSC VOICE, LLC (1). The earliest assignment on record here is 2014-10-03 and the most recent 2024-03-13. 3 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 270, 931 – overlay codes cover the same geography, so a rate center is served by all of them.
