* Driver's side doorjamb: This is the most common location for the paint code sticker. Look closely at the sticker on the doorjamb; it will often have a code, usually starting with a letter or number followed by a few more characters (e.g., WA8555, 28U).
* Inside the glove compartment: Sometimes, the paint code is located on a sticker inside the glove compartment.
* Service manual: If you have the owner's manual or a service manual for your specific 2007 Avalanche, the paint code may be listed there.
* Vehicle Identification Number (VIN): The VIN itself doesn't contain the paint code, but a dealer or parts specialist can look up the code using the VIN in their system.
* Dealer: Your local Chevrolet dealer will be able to find the paint code for your vehicle using your VIN.
If you can't find it anywhere else, taking the VIN to a Chevrolet dealer is the most reliable method.
