RUDYARD prefixes in area code 906

NANPA records 5 assigned NXX blocks to rate center RUDYARD in area code 906, 1.4% of the 360 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. 5 holders hold those blocks, the largest being COMCAST IP PHONE, LLC (1), INTERACTIVE SERVICES NETWORK, INC. (1), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2004-12-06 and the most recent 2023-03-21. 2 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 406 – overlay codes cover the same geography, so a rate center is served by all of them.
