SOUTHINGTN prefixes in area code 860
NANPA records 19 assigned NXX blocks to rate center SOUTHINGTN in area code 860, 2.4% 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. 10 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), NEW CINGULAR WIRELESS PCS, LLC - DC (2). 16 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 code 959 – overlay codes cover the same geography, so a rate center is served by all of them.
