How to Validate a Barcode
Step 1: Input the barcode
Enter the barcode digits you wish to validate. Ensure the number matches the expected format (e.g., 13 digits for EAN-13).
Step 2: Choose barcode format
Select the correct barcode format (EAN-13, UPC, CODE128, etc.). Each format has its own validation rules including length and checksum requirements.
Step 3: Click Validate
Click the validate button to run the validation check. The system will analyze the code structure and checksum (if applicable).
Step 4: View validation result
You’ll see whether the barcode is valid or not. If invalid, a message will indicate what's wrong (e.g., incorrect length or invalid checksum).

More about Barcode Validation
A validator commonly checks the following items:
- Length rules: Correct length for the selected standard (EAN-13 has 13 digits, UPC-A has 12).
- Character set: Only valid characters (numeric-only for EAN/UPC, alphanumeric for Code 39/Code 128).
- Check digit: Calculation for standards that support it (EAN-13, UPC-A, EAN-8, ITF).
- Format consistency: Basic format consistency like prefixes or leading zeros when required.
Common validation targets include:
- EAN-13 / EAN-8 / UPC-A / UPC-E: Numeric codes with check digit validation.
- ITF (Interleaved 2 of 5): Used in cartons and logistics, often with check digit rules.
- Code 39 / Code 128: Structure and character set validation (basic sanity checks).
- 2D codes (optional): Some tools also check QR/Data Matrix, but rules differ from linear barcodes.
- Wrong number of digits for the selected format.
- Invalid characters (spaces, symbols, or letters in numeric codes).
- Incorrect check digit due to typo or truncated number.
- Leading zero removed or added when not expected by the system.
