MARIETTA prefixes in area code 740

NANPA records 16 assigned NXX blocks to rate center MARIETTA in area code 740, 2.0% 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. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (4), OHIO BELL TEL CO (4), AERIAL COMMUNICATIONS, INC. (2). The earliest assignment on record here is 2001-06-26 and the most recent 2013-11-11. 11 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 220, 223, 309, 317 – overlay codes cover the same geography, so a rate center is served by all of them.
