ANSTED prefixes in area code 681
NANPA records 5 assigned NXX blocks to rate center ANSTED in area code 681, 1.0% of the 499 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 T-MOBILE USA, INC. (3), LUMOS NETWORKS INC. - VA (1), COMMIO, LLC (1). The earliest assignment on record here is 2023-09-15 and the most recent 2025-09-16. 5 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 304 – overlay codes cover the same geography, so a rate center is served by all of them.
