CARLETON prefixes in area code 734

NANPA records 8 assigned NXX blocks to rate center CARLETON in area code 734, 1.1% 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. 8 holders hold those blocks, the largest being METROPCS, INC. (1), LEVEL 3 COMMUNICATIONS, LLC - MI (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1). The earliest assignment on record here is 2014-10-15 and the most recent 2022-01-14. 8 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 402, 531 – overlay codes cover the same geography, so a rate center is served by all of them.
