DEXTER prefixes in area code 734
NANPA records 16 assigned NXX blocks to rate center DEXTER 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. 10 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - MI (3), ONVOY, LLCV - MI (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2). The earliest assignment on record here is 2005-09-12 and the most recent 2022-03-04. 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 207, 315, 478, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
