MANCHESTER prefixes in area code 636
NANPA records 27 assigned NXX blocks to rate center MANCHESTER in area code 636, 6.2% of the 435 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 SOUTHWESTERN BELL (9), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MO (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (4). The earliest assignment on record here is 2024-02-23 and the most recent 2026-04-02. 18 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 217, 223, 326, 351 – overlay codes cover the same geography, so a rate center is served by all of them.
