PORTSMOUTH prefixes in area code 740
NANPA records 28 assigned NXX blocks to rate center PORTSMOUTH in area code 740, 3.6% of the 786 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. 9 holders hold those blocks, the largest being FRONTIER NORTH, INC. - OH (13), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (4), NEW CINGULAR WIRELESS PCS, LLC - IL (4). The earliest assignment on record here is 2002-07-16 and the most recent 2012-03-14. 19 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 220, 401, 603, 712 – overlay codes cover the same geography, so a rate center is served by all of them.
