WARWICK prefixes in area code 845

NANPA records 8 assigned NXX blocks to rate center WARWICK in area code 845, 1.0% of the 783 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. 5 holders hold those blocks, the largest being ALTEVA OF WARWICK LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (2), CSC VOICE, LLC (1). The earliest assignment on record here is 2008-05-13 and the most recent 2023-03-21. 7 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 229, 401, 410, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
