FARMINGTON prefixes in area code 248
NANPA records 47 assigned NXX blocks to rate center FARMINGTON in area code 248, 6.0% 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. 12 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (17), NEW CINGULAR WIRELESS PCS, LLC - IL (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (5). The earliest assignment on record here is 2001-03-26 and the most recent 2023-12-15. 33 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, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
