HECTOR prefixes in area code 320

NANPA records 4 assigned NXX blocks to rate center HECTOR in area code 320, 0.8% of the 511 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. 4 holders hold those blocks, the largest being ONVOY, LLC - MN (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2004-05-19 and the most recent 2022-02-22. 3 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 479 – overlay codes cover the same geography, so a rate center is served by all of them.
