MISSION prefixes in area code 956

NANPA records 43 assigned NXX blocks to rate center MISSION in area code 956, 5.9% of the 735 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 STPCS JOINT VENTURE, LLC (15), SOUTHWESTERN BELL (9), NEW CINGULAR WIRELESS PCS, LLC - IL (8). The earliest assignment on record here is 2002-08-12 and the most recent 2024-02-01. 37 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 218, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
