ROMEO prefixes in area code 586
NANPA records 21 assigned NXX blocks to rate center ROMEO in area code 586, 3.8% of the 546 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. 13 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (4), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (3), LEVEL 3 COMMUNICATIONS, LLC - MI (3). The earliest assignment on record here is 2001-06-18 and the most recent 2023-07-20. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
