LA HONDA prefixes in area code 650

NANPA records 9 assigned NXX blocks to rate center LA HONDA in area code 650, 1.3% of the 717 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. 8 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1). The earliest assignment on record here is 2009-12-14 and the most recent 2009-12-14. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
