TORRINGTON prefixes in area code 860

NANPA records 15 assigned NXX blocks to rate center TORRINGTON in area code 860, 1.9% 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. 8 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (5), PAETEC ITEL, LLC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2015-02-23 and the most recent 2015-02-23. 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 307, 959 – overlay codes cover the same geography, so a rate center is served by all of them.
