* Driver's license: If you have a California driver's license, the DMV will be able to see the date that you first obtained your license. This date can be used to determine how long you have been a resident of the state.
* Vehicle registration: If you have previously registered a vehicle in California, the DMV will have a record of that registration. This record can be used to determine how long you have been a resident of the state.
* Other documents: The DMV may also request other documents to verify your residency, such as a utility bill or a lease agreement. These documents can help to prove that you have been living in California for at least six months.
If the DMV is unable to verify that you have been a resident of California for at least six months, you may be required to pay a non-resident fee when you register your vehicle.
