What counts as proof of registration in California
In California, proof of registration is the official document showing your vehicle is registered with the DMV. The state issues this as a wallet-sized card that comes in the mail after you register your vehicle. You must carry it with you whenever you drive — it is separate from your driver's license and your vehicle's title.
The registration card shows your vehicle's license plate number, the vehicle identification number (VIN), the registration expiration date, and your name and address. California law requires you to present this card to a peace officer if stopped, along with your driver's license and proof of insurance.
If you have lost your registration card, received a replacement plate, or moved to a new address, you will need a new registration card from the DMV. The card itself is free — you only pay if your registration itself is due for renewal.
Key Takeaways
- California's registration card is a wallet-sized document mailed to you after registration and must be carried while driving.
- The card shows your plate number, VIN, expiration date, and address, and you must show it to officers during a traffic stop.
- A lost, damaged, or outdated registration card can be replaced through the DMV by mail, online, or in person.
- Temporary registration documents (like a registration notice) are not the same as the permanent registration card and have different rules.
- Scammers sometimes pose as the DMV to collect registration information — the real DMV will never ask for your Social Security number by email or phone.
The difference between a registration card and a registration notice
When you first register a vehicle or renew your registration, the DMV sends you two documents. The registration notice is a larger form that arrives first and shows your renewal details, fees, and expiration date. This is not proof of registration for driving purposes.
The registration card arrives separately, usually within two weeks. This is the document you must carry in your vehicle. If you are stopped by police and only have the notice, you may still receive a citation for not having the card, even though the registration itself is current.
Keep both documents, but understand that only the card satisfies the legal requirement to carry proof of registration. The notice is useful for your records and for reference when you need to know your registration details.
How to replace a lost or damaged registration card
If your registration card is lost, stolen, or damaged, you can request a replacement through three methods: online, by mail, or in person at a DMV office.
Online replacement is the fastest option if your registration is current. Visit the California DMV website, select "Replace a Registration Card," and follow the prompts. You will need your license plate number or VIN. The replacement card will be mailed to the address on file, usually within 7 to 10 business days. There is no fee for this service.
By mail, send a letter to your local DMV office requesting a replacement card. Include your name, address, license plate number or VIN, and a brief explanation of why you need a replacement. Mail it to the address listed on the DMV website for your county. Processing takes 2 to 3 weeks.
In person at a DMV office, bring your driver's license and tell the staff member you need a replacement registration card. They can print one on the spot, though some offices may mail it instead. Call ahead to confirm your local office's process.
What to do if your registration has expired
If your registration card shows an expiration date that has passed, you cannot legally drive the vehicle. You must renew your registration with the DMV before using the car on public roads.
Renewal can be done online, by mail, or in person, depending on your vehicle type and whether you have any outstanding violations or fees. Once you renew, a new registration card will be mailed to you. Until it arrives, you should not drive the vehicle, even if you have paid the renewal fee — the law requires the current card to be in the vehicle.
If you are stopped while driving with an expired registration, you can face a fine. The officer may also cite you if you cannot produce the current card, even if your registration is technically current but the card has not yet arrived.
Temporary registration documents and what they mean
When you purchase a new vehicle from a dealer, you receive a temporary registration permit or registration notice instead of the permanent card. This document is valid for a set number of days (usually 30 to 90 days, depending on the dealer's processing) and serves as proof of registration during that period.
Temporary permits are printed on larger paper and are not the same as the wallet-sized permanent card. Law enforcement recognizes them as valid proof during the temporary period. Once your permanent registration card arrives in the mail, the temporary permit is no longer valid and should be discarded.
If you buy a used vehicle from a private seller, the previous owner's registration card transfers to you only if you complete the transfer with the DMV. Until you do, you should not drive the vehicle. The seller may give you a temporary document, but this does not replace the need to register it in your name.
Scams involving registration cards and how to protect yourself
Scammers sometimes contact vehicle owners claiming to be from the DMV and asking for registration information, Social Security numbers, or payment for "registration renewal." The real California DMV will never contact you by email or phone asking for personal information or payment.
If you receive an unsolicited call, email, or text claiming to be from the DMV about your registration, do not respond. Hang up or delete the message. The DMV contacts you by mail only, and only when your registration is actually due for renewal.
If you need to verify whether a communication is real, call the DMV directly using the phone number on the official DMV website — not a number provided in the suspicious message. Never click links in emails claiming to be from the DMV, and never provide your Social Security number, driver's license number, or credit card information to anyone who contacts you unsolicited.
What to carry in your vehicle at all times
California law requires you to carry three documents while driving: your driver's license, your vehicle registration card, and proof of insurance. All three must be presented to a peace officer upon request during a traffic stop.
Keep your registration card in an easily accessible place in your vehicle — the glove compartment, sun visor, or door pocket. Do not leave it in a location where it might be damaged by heat or moisture. If the card becomes illegible, request a replacement.
If you are stopped and cannot produce your registration card, you may receive a citation even if your registration is current. The citation is for not carrying the card, not for having an expired registration. You can usually clear this citation by showing the card to the court or to the police department that issued the ticket.
Frequently Asked Questions
Can I use a photo of my registration card instead of carrying the physical card?
California law requires you to carry the physical registration card or a certified copy. A photo on your phone is not legally accepted. However, if you are stopped and do not have the card, you can sometimes show the officer a photo as a courtesy while you locate the physical card, but this does not satisfy the legal requirement and you may still receive a citation.
What if I moved and my registration card still shows my old address?
You must update your address with the DMV within 10 days of moving. You can do this online, by mail, or in person. Once you update your address, request a replacement registration card showing the new address. Driving with an outdated address can result in a citation.
How long does it take to get a replacement registration card?
Online replacements typically arrive within 7 to 10 business days. Mail requests take 2 to 3 weeks. In-person requests may be printed on the spot at some offices, though others will mail it. Call your local DMV office to confirm their process before visiting.
Do I need a new registration card if I change my vehicle's license plate?
Yes. When you change your plate — whether due to damage, personalization, or a new registration — the DMV will mail you a new registration card showing the new plate number. Do not drive with the old card once your plate has been changed, as the numbers will not match.
What happens if I get pulled over and my registration card is in the mail?
If your registration is current but the card has not yet arrived, you can show the officer your registration notice or a receipt from your online renewal. This may satisfy the officer, but you are technically in violation of the law requiring you to carry the card. To avoid this, keep your old card until the new one arrives.
