ROYAL OAK prefixes in area code 947
NANPA records 11 assigned NXX blocks to rate center ROYAL OAK in area code 947, 5.2% of the 211 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. 4 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - MI (7), METROPCS, INC. (2), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (1). The earliest assignment on record here is 2018-02-09 and the most recent 2024-03-15. 11 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 248 – overlay codes cover the same geography, so a rate center is served by all of them.
