Locate the Code
Place the Mystery Car package face down.
A five-character code is located on the back of the package. On 2008, 2009 and 2010 packages, the code is located toward the top under the words "Mystery Cars."
The code consists of a combination of letters and numbers. A typical code would be "P2487."
Matching the codes to the cars often requires patience, because the codes are not immediately released by the manufacturer. Hot Wheels releases the codes sometime during each year. In the meantime, collectors often post codes online as they are discovered.
The codes from the 2005 to 2010 series are listed on the Hot Wheels Wiki, a collector's site. But until each year's codes are revealed, Mystery Cars live up to their name.
