Good afternoon!

        The San Diego Superior Court has recently announced that they will begin using a new case numbering system.  The following text is taken from a press release available on the court's website.  Immediately following this text is a list of all 58 California counties and the code number assigned to them.  With this system, you will know that if a superior court case number starts with a "19," the court is located in Los Angeles County, no matter what the attorney tells you otherwise.  San Diego County was one of the first to start using a new case management system so it may be awhile before other counties are using this new numbering system.  That means you are on the cutting edge of something new!

The San Diego Superior Court is in the process of implementing a new statewide case management system (known as CCMS V3) for Civil, Small Claims, and Probate.

The system is currently operating in the Central Division Small Claims-Kearny Mesa, the Small Claims Appeals section of the Downtown Courthouse, North County Civil and Small Claims, and will go live in the Hall of Justice, Main Courthouse Downtown, East, South, and Probate locations by mid-May 2007.

Court users will see some significant changes in the foreseeable future, but one major change that will go into effect as each site implements the new system is a new case number.

The standardized statewide case number format is as follows:

37-YYYY-00000519-CC-CT-LLL

               Breach of Contract (BC), Collections (CL), and Unlawful Detainer (UD)
