OKLA CITY prefixes in area code 572
NANPA records 41 assigned NXX blocks to rate center OKLA CITY in area code 572, 35.0% of the 117 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. 18 holders hold those blocks, the largest being UNITED STATES CELLULAR - OK (19), ONVOY, LLC - OK (4), TELEPORT COMMUNICATIONS AMERICA OK - LLC (2). The earliest assignment on record here is 2021-04-12 and the most recent 2025-12-29. 41 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 405 – overlay codes cover the same geography, so a rate center is served by all of them.
