MT VERNON prefixes in area code 740

NANPA records 17 assigned NXX blocks to rate center MT VERNON in area code 740, 2.2% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (6), BRIGHTSPEED OF NORTHWEST OHIO, INC. (4), AERIAL COMMUNICATIONS, INC. (3). The earliest assignment on record here is 2001-01-10 and the most recent 2012-12-21. 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 207, 251, 319, 360 – overlay codes cover the same geography, so a rate center is served by all of them.
