CAMBRIDGE prefixes in area code 740
NANPA records 14 assigned NXX blocks to rate center CAMBRIDGE in area code 740, 1.8% 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. 6 holders hold those blocks, the largest being AERIAL COMMUNICATIONS, INC. (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (3), FRONTIER NORTH, INC. - OH (3). The earliest assignment on record here is 2001-05-03 and the most recent 2012-10-17. 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 208, 308, 309, 410 – overlay codes cover the same geography, so a rate center is served by all of them.
