NEW BOSTON prefixes in area code 734

NANPA records 16 assigned NXX blocks to rate center NEW BOSTON in area code 734, 2.3% of the 701 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3), LEVEL 3 COMMUNICATIONS, LLC - MI (3), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-05-01 and the most recent 2021-01-05. 15 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, 430, 603, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
