The DMV may ask for your insurance provider’s NAIC number as a way to easily link your coverage with a specific company. Additionally, it’s not uncommon for the DMV to ask for your company’s NAIC number if it is involved during the claims process. Essentially, the DMV has a database in which your insurance provider’s NAIC code provides the DMV vital information about your insurance company, such as your insurer’s address or the states the company is licensed in.
