Your renewal identification number is a code the California DMV mails to you before your registration expires

When your vehicle registration is about to expire, the California DMV sends you a renewal notice in the mail. That notice includes a renewal identification number — a unique code printed on the form that matches your vehicle and registration record. You use this number when you renew online, by mail, or in person at a DMV office. Without it, the DMV cannot connect your payment to the correct vehicle and registration account.

The renewal notice arrives roughly 60 days before your registration expires. The renewal identification number appears in the upper right corner of the notice, usually as a series of numbers and letters. If you cannot find your notice or the number is unclear, you can look it up through your DMV account online or call the DMV to have it read to you.

Key Takeaways

  • The renewal identification number is printed on the renewal notice the DMV mails you before your registration expires.
  • You need this number to renew your registration online, by mail, or at a DMV office — it connects your payment to your vehicle record.
  • If you lose the notice, you can find the number through your DMV online account or by calling the DMV customer service line at 1-800-777-0133.
  • The number is specific to that renewal cycle and changes each time your registration comes due.

Where to find your renewal identification number

The DMV renewal notice is a multi-part form that arrives at the address on file for your vehicle. The renewal identification number is printed in the top right corner of the main notice page, usually in a box labeled "Renewal ID" or similar. It is a combination of numbers and letters, typically 10 to 12 characters long.

If you have already lost or misplaced the notice, you have two ways to locate the number without requesting a replacement form. Log into your DMV account at dmv.ca.gov using your driver license number and date of birth, then navigate to your vehicle registration section — the renewal identification number will appear there. Alternatively, call the DMV customer service line at 1-800-777-0133 and provide your vehicle identification number (VIN) and license plate number; a representative can read the number to you over the phone.

How to use your renewal identification number

When you renew your registration, you will enter this number into the system regardless of which method you choose. If renewing online at dmv.ca.gov, you will be prompted to enter it on the renewal form before you pay. If renewing by mail, write the number on the check or money order and include the renewal notice itself in the envelope. If renewing in person at a DMV office, bring the renewal notice with you — the staff member will scan or manually enter the number.

The renewal identification number ensures the DMV credits your payment to the correct vehicle and registration account. Without it, your payment may be delayed or applied to the wrong record, which can result in your registration remaining expired even though you have paid. Double-check the number before submitting your renewal to avoid processing errors.

What to do if you cannot locate your renewal notice

If your renewal notice has not arrived and your registration is within 30 days of expiring, contact the DMV when ready. Call 1-800-777-0133 or visit a DMV office in person. Bring your vehicle registration card and driver license. The DMV can print a duplicate renewal notice on the spot or provide the renewal identification number verbally so you can proceed with renewal.

If your notice arrived but the renewal identification number is smudged, faded, or illegible, do not guess at the digits. Call the DMV or log into your online account to confirm the correct number. Entering an incorrect number will cause the renewal to fail or attach to the wrong vehicle. The DMV can verify the correct number in seconds over the phone.

Scam alert: Fake renewal notices

Scammers sometimes send fake DMV renewal notices by mail or email that look similar to the real form. These fake notices often include a phone number or website that is not the official DMV and ask you to pay a fee or provide personal information. The real California DMV renewal notice will always come from the official DMV mailing address and will direct you to dmv.ca.gov or the official customer service number 1-800-777-0133.

Never pay a renewal fee to a number or website that contacted you first. Always initiate contact yourself by calling the official DMV number or visiting dmv.ca.gov directly. If you receive a suspicious renewal notice, report it to the California Attorney General's office at oag.ca.gov. Legitimate renewal notices never ask for payment by gift card, wire transfer, or cryptocurrency.

Renewing online versus by mail or in person

Online renewal is the fastest method and requires only your renewal identification number, vehicle information, and a payment method. You can complete it in minutes at dmv.ca.gov, and your new registration is typically mailed within two weeks. By-mail renewal takes longer — you mail the notice with payment, and processing usually takes three to four weeks. In-person renewal at a DMV office is when ready if you bring all required documents, but wait times at offices vary by location and time of day.

Regardless of method, you must have the renewal identification number or the original renewal notice. If you are renewing in person and have lost the notice, bring your vehicle registration card and driver license so the DMV can look up your information and provide the number. Online renewal is often the most reliable option because you receive when ready confirmation that your payment was processed correctly.

What happens if your registration expires before you renew

If your registration expires before you submit your renewal, you cannot legally drive the vehicle. Driving with an expired registration can result in a traffic citation and fine. However, you can still renew after the expiration date — the renewal identification number remains valid. When you renew late, you may owe a late fee in addition to the standard renewal fee.

Contact the DMV or check your online account to confirm the total amount due before you submit your renewal. Late fees vary depending on how long your registration has been expired, so it is worth checking rather than guessing. The sooner you renew after expiration, the lower your late fees will be.

Frequently Asked Questions

Can I renew my registration without the renewal identification number?

No. The renewal identification number is required to process your renewal online or by mail. If you renew in person at a DMV office without the number, staff can look it up using your VIN and license plate, but you still need to provide those details. Always have either the renewal notice or your vehicle information ready.

Is the renewal identification number the same as my vehicle registration number?

No. Your vehicle registration number is a permanent identifier for your vehicle. The renewal identification number is a temporary code specific to that renewal cycle and changes each time your registration comes due. They are printed on different parts of the renewal notice.

What if I have multiple vehicles — do I get a separate renewal identification number for each?

Yes. Each vehicle registration renews on its own schedule, and each renewal notice includes its own unique renewal identification number. Keep the notices separate and use the correct number for each vehicle when you renew.

Can I renew my registration if I moved and did not receive the renewal notice?

Yes, but you should update your address with the DMV first. If you have moved since your last registration, the renewal notice may have gone to your old address. Update your address at dmv.ca.gov or at a DMV office, then request a duplicate renewal notice or look up your renewal identification number through your online account.

How long is the renewal identification number valid?

The renewal identification number is valid until your registration expires. Once your registration is renewed, that number is no longer used. If you do not renew before the expiration date, you will receive a new renewal notice with a new renewal identification number if you renew late.
