How do I apply for an ORI?

You must go on the Department of Justice Website and search for Applicant Agencies. 

http://oag.ca.gov/fingerprints/agencies or email "appagencyquestions@doj.ca.gov." 

This will give you instructions on how to apply for the ORI. You can email this to the person asking for the info. But it's not set up through Certifix, it's through the California Department of Justice. 

For an agency to get their ORI it can take 4-6 weeks. (Per Maha) If 6 weeks passed and they still haven't received any word from the DOJ they can contact the ORI Department directly at (916) 227-7332. 

Since Personnel frequently change at the DOJ I can't give you a specific name but this number isn't an automated line.
