Sheriff's Office Missing Persons

Law enforcement agencies in California do not require a person to wait a specific period of time before reporting a person as missing.

If you have information about a missing person or want to file a report in regards to a missing person please contact the San Mateo County Sheriff’s Office at 650-363-4000 (24-hours a day). If you believe a missing person is in danger, please call 9-1-1 immediately.

Investigations regarding missing persons present a genuine challenge to law enforcement professionals. Fortunately, public awareness and concern about missing persons continues to grow. Things you may be able to provide during an ongoing missing persons investigation include: dental records of the missing person, personal items belonging to the missing person that may contain their DNA (toothbrush, hairbrush), DNA samples of blood relatives, and current photographs of the missing person. Please contact the San Mateo County Sheriff's Office if you would like to submit any of these aforementioned items.
