YOUNGSTOWN prefixes in area code 330

NANPA records 86 assigned NXX blocks to rate center YOUNGSTOWN in area code 330, 10.9% of the 787 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. 15 holders hold those blocks, the largest being OHIO BELL TEL CO (30), NEW CINGULAR WIRELESS PCS, LLC - IL (15), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (13). The earliest assignment on record here is 2001-04-24 and the most recent 2019-12-17. 33 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 234, 716 – overlay codes cover the same geography, so a rate center is served by all of them.
