OFALLON prefixes in area code 636
NANPA records 24 assigned NXX blocks to rate center OFALLON in area code 636, 5.5% 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. 11 holders hold those blocks, the largest being BRIGHTSPEED OF MISSOURI, LLC (8), NEW CINGULAR WIRELESS PCS, LLC - IL (4), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2001-08-08 and the most recent 2026-05-13. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
