PACIFIC prefixes in area code 636
NANPA records 6 assigned NXX blocks to rate center PACIFIC in area code 636, 1.4% 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. 4 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), ONVOY, LLC - MO (2), LEVEL 3 COMMUNICATIONS, LLC - MO (1). The earliest assignment on record here is 2003-01-10 and the most recent 2016-01-05. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
