FORTGIBSON prefixes in area code 918
NANPA records 3 assigned NXX blocks to rate center FORTGIBSON in area code 918, 0.4% of the 782 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - OK (1), ONVOY, LLC - OK (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2013-08-14 and the most recent 2013-08-14. 3 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 code 539 – overlay codes cover the same geography, so a rate center is served by all of them.
