WARREN prefixes in area code 234
NANPA records 12 assigned NXX blocks to rate center WARREN in area code 234, 3.0% of the 398 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. 10 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), VONAGE AMERICA LLC (1). The earliest assignment on record here is 2011-01-12 and the most recent 2025-03-26. 12 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, 260 – overlay codes cover the same geography, so a rate center is served by all of them.
