ROYAL OAK prefixes in area code 248
NANPA records 84 assigned NXX blocks to rate center ROYAL OAK in area code 248, 10.7% of the 784 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. 14 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (36), NEW CINGULAR WIRELESS PCS, LLC - IL (12), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (6). The earliest assignment on record here is 2001-05-02 and the most recent 2024-12-30. 41 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 947 – overlay codes cover the same geography, so a rate center is served by all of them.
