HARTFORD prefixes in area code 860
NANPA records 260 assigned NXX blocks to rate center HARTFORD in area code 860, 33.2% 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. 18 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (110), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CT (31), NEW CINGULAR WIRELESS PCS, LLC - DC (21). The earliest assignment on record here is 2001-03-26 and the most recent 2020-11-10. 139 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 234, 262, 269, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
