PLACENTIA prefixes in area code 657
NANPA records 11 assigned NXX blocks to rate center PLACENTIA in area code 657, 1.6% 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. 7 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2011-04-04 and the most recent 2026-06-12. 11 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 code 714 – overlay codes cover the same geography, so a rate center is served by all of them.
