ORANGE prefixes in area code 657
NANPA records 42 assigned NXX blocks to rate center ORANGE in area code 657, 6.0% of the 703 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (9), NEW CINGULAR WIRELESS PCS, LLC (8), T-MOBILE USA, INC. (6). The earliest assignment on record here is 2011-12-05 and the most recent 2026-04-21. 42 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 351, 409, 540, 714 – overlay codes cover the same geography, so a rate center is served by all of them.
