HOWARDSGRV prefixes in area code 920

NANPA records 3 assigned NXX blocks to rate center HOWARDSGRV in area code 920, 0.4% of the 785 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 EASTCOAST TELECOM, INC. (1), TWC IP ENABLED SERVICES, LLC (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1). The earliest assignment on record here is 2023-09-26 and the most recent 2023-09-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
