PLYMOUTH prefixes in area code 734
NANPA records 44 assigned NXX blocks to rate center PLYMOUTH in area code 734, 6.3% 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. 13 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (17), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (4). The earliest assignment on record here is 2001-04-02 and the most recent 2026-09-25. 33 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, 209, 252, 272 – overlay codes cover the same geography, so a rate center is served by all of them.
