NANPA records 39 assigned NXX blocks to rate center MURRIETA in area code 951, 5.6% of the 696 blocks assigned in the code.

(6), T-MOBILE USA, INC. (6). The earliest assignment on record here is 2001-07-17 and the most recent 2025-10-09. 33 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
