My wife applied for her REAL ID complaint California Driver License in mid April. She brought the documents required to prove her identity, residence and Social Security number. Three of those had our home address. She received the new license a week later.
Today, she received a letter claiming that she provided only one residency document. It asked her check a box confirming that the mailing address was correct, sign, date and send it back to the DMV in an enclosed prepaid envelope in order to satisfy the second residency requirement.
