ST JOSEPH prefixes in area code 816

NANPA records 40 assigned NXX blocks to rate center ST JOSEPH in area code 816, 5.1% of the 785 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. 12 holders hold those blocks, the largest being SOUTHWESTERN BELL (14), AERIAL COMMUNICATIONS, INC. (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (5). The earliest assignment on record here is 2001-08-10 and the most recent 2024-03-15. 31 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, 269, 318, 320 – overlay codes cover the same geography, so a rate center is served by all of them.
