WARRENSBG prefixes in area code 660

NANPA records 14 assigned NXX blocks to rate center WARRENSBG in area code 660, 2.7% of the 518 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 AERIAL COMMUNICATIONS, INC. (4), EMBARQ MISSOURI, INC. DBA CENTURYLINK - MO (4), LEVEL 3 COMMUNICATIONS, LLC - MO (1). The earliest assignment on record here is 2001-06-25 and the most recent 2021-09-08. 10 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, 518, 838 – overlay codes cover the same geography, so a rate center is served by all of them.
