WRIGHTSVL prefixes in area code 501

NANPA records 3 assigned NXX blocks to rate center WRIGHTSVL in area code 501, 0.5% of the 631 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 WINDSTREAM COMMUNICATIONS, INC. - AR (1), ONVOY, LLC - AR (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2019-10-10 and the most recent 2019-10-10. 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 223, 478, 717 – overlay codes cover the same geography, so a rate center is served by all of them.
