FARMINGTON prefixes in area code 947

NANPA records 19 assigned NXX blocks to rate center FARMINGTON in area code 947, 9.0% of the 211 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 - IL (15), BANDWIDTH.COM CLEC, LLC - MI (1), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (1). The earliest assignment on record here is 2020-01-17 and the most recent 2026-09-01. 19 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.
