How to Find Arizona ADOT Numbers for Auto Insurance Companies

What Is an Arizona ADOT Number for Auto Insurance?

In Arizona, auto insurance companies must be authorized to provide financial responsibility coverage for vehicles registered in the state. ADOT assigns a carrier-specific identifier — sometimes called an ADOT number or FR (financial responsibility) number — that links an insurance company to the state's vehicle registration and SR-22 systems. This number appears on insurance cards, policy declarations, and electronic filings. If you need to verify coverage or register a vehicle, having the correct ADOT number speeds up the process.

Where to Find an Insurance Company's Arizona ADOT Number

The most direct method is through ADOT's own online resources. Arizona's Motor Vehicle Division website allows you to look up licensed insurance carriers. You can also find the number on the insurance documents the company provides you. Here are the primary places to search:

• The insurance company's website or agent portal. Most carriers list their Arizona-specific licensing and ADOT carrier number on their website's licensing or compliance page, or you can ask your agent directly.
• The declarations page of your policy. The ADOT or FR number is typically printed on your insurance declarations page, often near the policy number and carrier name.
• The physical insurance card. Some Arizona insurance cards include the carrier's ADOT identifier alongside the policy number.
• The Arizona Department of Insurance and Financial Institutions (DFI) website. DFI maintains a searchable database of licensed insurance carriers operating in Arizona. You can look up a company's license status and sometimes find the associated ADOT number.
• ADOT's MVD online services. ADOT's Motor Vehicle Division website may let you verify a carrier's status or look up the ADOT number linked to a specific policy or SR-22 filing.

Why You Need the ADOT Number

Several Arizona processes require you to reference an insurance company's ADOT number:

• Vehicle registration and renewal. Arizona requires proof of financial responsibility. The ADOT number helps MVD confirm your carrier is authorized to issue policies in the state.
• SR-22 filings. If a court orders you to file an SR-22, the insurance company submits the form using its ADOT number. You may need this number to confirm the filing was received.
• Insurance verification requests. Law enforcement or MVD officers can use the ADOT number to verify coverage electronically through Arizona's insurance verification system.
• Disputes or claims verification. If there is a question about whether a policy is valid in Arizona, the ADOT number provides a trail back to the carrier's state-authorized status.

What If the Number Is Not Found?

Sometimes the ADOT number is not publicly listed or easily searchable. This can happen with smaller carriers, surplus-line insurers, or newly licensed companies. In those cases, the most reliable path is to ask the insurance company directly. A licensed agent or the carrier's underwriting department can supply the number and confirm it is active for Arizona. You should also verify that the company holds a valid Arizona license through the DFI database before relying on any ADOT number they provide.

Tips to Keep the Number Handy

Once you have the ADOT number, save it in a secure place. Many people photograph their insurance card and declarations page and store them in a cloud drive or password manager. Having the number saved means you can provide it instantly during a traffic stop, registration appointment, or SR-22 verification without needing to call your insurer each time.
