PERRIS prefixes in area code 951

NANPA records 55 assigned NXX blocks to rate center PERRIS in area code 951, 7.9% of the 696 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. 13 holders hold those blocks, the largest being T-MOBILE USA, INC. (30), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (7), FRONTIER CALIFORNIA INC. (5). The earliest assignment on record here is 2002-03-22 and the most recent 2026-08-07. 52 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
