- EAN (European Article Number): Common in Europe.
- QR Codes: These can store more complex information, including URLs.

Where to Find Expiration Dates
Not all barcodes will include an expiration date, but when they do, it is typically found in a specific format within the barcode. Manufacturers encode this information to facilitate quicker processing during checkout and inventory management.
Common Formats of Expiration Dates
Typically, expiration dates in barcodes can be formatted in several ways, such as:
- YYMMDD: Year, Month, Day
- MMDDYY: Month, Day, Year
For example:
