UNION prefixes in area code 636
NANPA records 12 assigned NXX blocks to rate center UNION in area code 636, 2.8% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), SOUTHWESTERN BELL (3), LEVEL 3 COMMUNICATIONS, LLC - MO (2). The earliest assignment on record here is 2002-02-28 and the most recent 2024-12-17. 11 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, 269, 304, 360 – overlay codes cover the same geography, so a rate center is served by all of them.
