HARWINTON prefixes in area code 860
NANPA records 9 assigned NXX blocks to rate center HARWINTON in area code 860, 1.1% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (3), SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (2), LEVEL 3 COMMUNICATIONS, LLC - CT (2). The earliest assignment on record here is 2001-12-14 and the most recent 2001-12-14. 7 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.
