FARMINGTON prefixes in area code 505
NANPA records 68 assigned NXX blocks to rate center FARMINGTON in area code 505, 9.9% of the 685 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (34), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NM (8), QWEST CORPORATION (8). The earliest assignment on record here is 2001-09-21 and the most recent 2026-10-21. 52 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.
