When you buy a policy from an auto insurance company offering SR22 services authorized to do business in the State of Oregon, you must ask the company to issue the SR22 to the state in certificate form that complies with the format requirement.
How will you know if it complies? You can have your agent issue a generic SR22 certificate on an approved ACORD form. They will know what that is. Most likely, the insurance carrier has obtained a unique or proprietary SR22 certificate approved for use. The Department of Motor Vehicles in Salem, Oregon, maintains a list of all insurance companies authorized to do business in Oregon, along with examples of the proprietary forms each company has obtained approval for.
Sometimes mistakes are made, and the DMV will reject a certificate. If they reject the certificate, it is usually mailed back to the driver needing the SR22 with a letter that allows him 10 days to provide a valid certificate on an approved form. If this happens, have your agent or company issue a new one on an approved generic ACORD form or call and discuss the issue with the SR22 unit of the Oregon DMV at 503-299-9999.
