"New" Valley Area Code Uncalled For?

Just saw that LA Observed has blogged a story from the Daily News about the mysterious, enigmatic "747" area code. Apparently it was supposed to have begun infiltrating the "818" codes in the crowded San Fernando Valley six months ago.

The Daily News has announced the odd fact that "the first 747 number has yet to be assigned." The story goes on to say that spokespeople for phone service providers, the California Public Utilities Commission and the North American Numbering Plan Administration could not "identify any 747 numbers assigned to residential or business customers."

Yet, in a Google and Wikipedia search I came up with two businesses using the "747" area code as of October. Will this Valley mystery ever be decoded?
