SYVNHLSHWD prefixes in area code 501
NANPA records 13 assigned NXX blocks to rate center SYVNHLSHWD in area code 501, 2.1% 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. 7 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), WINDSTREAM COMMUNICATIONS, INC. - AR (2), LEVEL 3 COMMUNICATIONS, LLC - AR (2). The earliest assignment on record here is 2002-05-06 and the most recent 2026-06-12. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
