HARTFORD prefixes in area code 262

NANPA records 11 assigned NXX blocks to rate center HARTFORD in area code 262, 1.7% of the 634 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 WISCONSIN BELL INC (2), CHARTER IP ENABLED SERVICES, LLC (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2018-04-09 and the most recent 2024-02-29. 8 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, 269, 270, 330 – overlay codes cover the same geography, so a rate center is served by all of them.
