PORTSMOUTH prefixes in area code 401
NANPA records 13 assigned NXX blocks to rate center PORTSMOUTH in area code 401, 2.2% of the 581 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 NEW CINGULAR WIRELESS PCS, LLC - DC (3), PAETEC ITEL, LLC (2), VERIZON NEW ENGLAND INC. (2). The earliest assignment on record here is 2002-07-18 and the most recent 2016-10-05. 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 220, 603, 712, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
