HARTLAND prefixes in area code 810

NANPA records 7 assigned NXX blocks to rate center HARTLAND in area code 810, 1.4% of the 509 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. 7 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1), CENTURYLINK COMMUNICATIONS, LLC (1), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2002-03-27 and the most recent 2022-03-15. 6 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 207, 262, 507, 802 – overlay codes cover the same geography, so a rate center is served by all of them.
