Match every identifying detail requested by the official notice.

Start with the package
Look for the lot or batch code, use-by date, model or serial number on the label. The exact location depends on the product; official notice photos can help you find it.
Compare the entire code
Keep letters, digits and date formats intact. A matching brand or barcode alone does not show that the package falls within a specified lot range. If the code is unclear, use the contact details in the official notice.
Vehicles use a different check
A make, model and year identify candidate campaigns. Use NHTSA or the manufacturer to check the individual vehicle identification number and whether its remedy has been completed.
