HARTFORD prefixes in area code 334

NANPA records 5 assigned NXX blocks to rate center HARTFORD in area code 334, 0.6% of the 784 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 - GA (1), BRIGHTSPEED OF ALABAMA, LLC - SOUTHERN (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2006-10-25 and the most recent 2023-08-10. 4 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.
