WARREN prefixes in area code 586
NANPA records 132 assigned NXX blocks to rate center WARREN in area code 586, 24.2% 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. 16 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (40), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (20), AMERICAN MESSAGING SERVICES, LLC (16). The earliest assignment on record here is 2001-02-15 and the most recent 2023-06-22. 86 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 codes 207, 208, 218, 234 – overlay codes cover the same geography, so a rate center is served by all of them.
