OVERTON prefixes in area code 702

NANPA records 3 assigned NXX blocks to rate center OVERTON in area code 702, 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. 2 holders hold those blocks, the largest being MOAPA VALLEY TEL. CO. (2), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2005-01-12 and the most recent 2005-01-12. 1 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 308, 430, 903 – overlay codes cover the same geography, so a rate center is served by all of them.
