LEON prefixes in area code 316

NANPA records 3 assigned NXX blocks to rate center LEON in area code 316, 0.9% of the 341 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. 2 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), FRACTEL, LLC (1). The earliest assignment on record here is 2021-07-06 and the most recent 2021-07-06. 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 codes 208, 304, 641, 681 – overlay codes cover the same geography, so a rate center is served by all of them.
