NANPA records 16 assigned NXX blocks to rate center LOS ALAMOS in area code 505, 2.3% of the 685 blocks assigned in the code.

The earliest assignment on record here is 2003-07-30 and the most recent 2024-03-21. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
