FARMINGTON prefixes in area code 385

NANPA records 7 assigned NXX blocks to rate center FARMINGTON in area code 385, 1.4% of the 495 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. 6 holders hold those blocks, the largest being ONVOY, LLC - UT (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2013-05-16 and the most recent 2022-04-04. 7 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, 209, 235, 248 – overlay codes cover the same geography, so a rate center is served by all of them.
