Supported barcode formats

FAQ
- What barcode number should I enter?
- Use the printed digits under the bars—usually 12 digits (UPC-A, common in the US) or 13 digits (EAN-13). You can type or paste them.
- Can I look up any food barcode?
- We focus on packaged grocery products with barcodes in Open Food Facts and related sources. Very new or regional items may be missing.
- Why didn’t my barcode return a result?
- The product may not be in the database yet, the code may be wrong or incomplete, or nutrition data may be too thin to score safely.
- Does this work for international products?
- EAN-13 and many standard retail formats are supported. Coverage still depends on what’s in the data sources we query.
- Is typing a barcode as accurate as scanning?
- Yes—the same digits are sent for lookup. Scanning only helps you capture the code faster when the camera can read it.
