CORONA prefixes in area code 951
NANPA records 88 assigned NXX blocks to rate center CORONA in area code 951, 12.6% 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. 19 holders hold those blocks, the largest being PACIFIC BELL (21), T-MOBILE USA, INC. (12), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (12). The earliest assignment on record here is 2001-02-22 and the most recent 2026-07-21. 63 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 575, 909 – overlay codes cover the same geography, so a rate center is served by all of them.
