FORTTOWSON prefixes in area code 580
NANPA records 5 assigned NXX blocks to rate center FORTTOWSON in area code 580, 0.7% of the 741 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. 5 holders hold those blocks, the largest being ONVOY, LLC - OK (1), AT&T ENTERPRISES, LLC (1), TELEPORT COMMUNICATIONS AMERICA OK - LLC (1). The earliest assignment on record here is 2011-03-28 and the most recent 2023-10-27. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
