WYOMING prefixes in area code 570

NANPA records 6 assigned NXX blocks to rate center WYOMING in area code 570, 0.8% of the 782 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. 6 holders hold those blocks, the largest being PAETEC ITEL, LLC (1), ONVOY, LLC - PA (1), CTSI, INC. - PA (1). 6 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 309, 563, 585 – overlay codes cover the same geography, so a rate center is served by all of them.
