SILVERADO prefixes in area code 714
NANPA records 8 assigned NXX blocks to rate center SILVERADO in area code 714, 1.0% of the 785 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2), T-MOBILE USA, INC. (2), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). The earliest assignment on record here is 2002-01-28 and the most recent 2015-02-23. 8 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 657 – overlay codes cover the same geography, so a rate center is served by all of them.
