PSDN LACN prefixes in area code 818
NANPA records 10 assigned NXX blocks to rate center PSDN LACN in area code 818, 1.3% of the 781 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 PACIFIC BELL (5), LEVEL 3 TELECOM OF CALIFORNIA, LP - CA (1), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). The earliest assignment on record here is 2001-01-25 and the most recent 2014-08-04. 6 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 747 – overlay codes cover the same geography, so a rate center is served by all of them.
