411 California
In California 411 can present some unique challenges. It is the most populous state in the US and so the amount of information necessary to cover the people and businesses within the state is correspondingly large.
There are companies that specialize specifically in individual metro areas such as San Francisco, San Diego, or Los Angeles. These companies narrow their focus to provide the best service possible for their coverage area. When you consider that the LA metro area is home to more people and businesses than some states, this becomes no small task.
California 411 is also limited by California’s privacy laws. These restrict whose information you can request via 411. For instance 411 companies are not allowed to give out the numbers or addresses of unlisted numbers. This becomes particularly important in the practice of reverse 411, where you can call to inquire about the person associated with a phone number.
