JEFFERSNCY prefixes in area code 573

NANPA records 39 assigned NXX blocks to rate center JEFFERSNCY in area code 573, 5.0% 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. 13 holders hold those blocks, the largest being EMBARQ MISSOURI, INC. DBA CENTURYLINK - MO (14), NEW CINGULAR WIRELESS PCS, LLC - IL (9), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2003-04-21 and the most recent 2023-03-27. 26 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 235, 865 – overlay codes cover the same geography, so a rate center is served by all of them.
