W BLOOMFLD prefixes in area code 947

NANPA records 4 assigned NXX blocks to rate center W BLOOMFLD in area code 947, 1.9% 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 OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (1), ONVOY, LLCV - MI (1), FRACTEL, LLC (1). The earliest assignment on record here is 2020-04-29 and the most recent 2022-01-07. 4 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.
