A California car registration consists of two main physical items: a paper certificate and two small stickers. The registration certificate is an 8.5" x 11" document that is folded to wallet-size. It contains all the key vehicle and owner information. The month and year stickers are placed on your license plate to show the expiration date. You must keep the paper registration in the vehicle as proof of valid registration.
The front of the certificate displays the most critical details for law enforcement and verification purposes. This includes the vehicle's license plate number, VIN (Vehicle Identification Number), registration expiration date, and the registered owner's name and address. The VIN is a unique 17-character code that acts like your car's fingerprint.
The back of the document has sections for a smog certification and a transfer of ownership, which are used when selling the vehicle. The two stickers are crucial. The month sticker (a number from 1 to 12) and the year sticker (e.g., '24) are affixed to the rear license plate. Newer certificates also include a barcode for quick electronic scanning by authorities.
Here is a summary of the key data fields found on a standard California registration certificate:

If you lose your registration, you can request a duplicate online through the DMV website, by mail, or in person at a DMV office for a fee. Always ensure the information is accurate to avoid complications during traffic stops or when selling your car.

It's that folded-up paper you keep in your glove box. The main thing is the front side—it’s got your name, your car's plate number, and the VIN. The expiration date is right there, big and bold. Don’t forget the little stickers! You peel them off and put them on your rear license plate so the month and year are visible. The whole point is to have that paper with you when you drive as proof you're registered.

From a design standpoint, it's a utilitarian document focused on clarity and security. The layout is dense with information but logically organized. Key fields like the license plate and expiration date are prominently placed for quick verification by law enforcement. While it's mostly text, the inclusion of a barcode adds a layer of digital security to prevent fraud. The paper itself may have subtle watermarks or patterns to deter counterfeiting. It’s function over form, but the function is well-considered.
