Code 11 Barcode Generator
Quick answer: Code 11 is a variable-length linear barcode designed primarily for digits 0–9 and the hyphen character.
What Code 11 is
Code 11 uses a compact linear pattern for numeric data plus hyphen. Implementations can use check characters depending on system requirements.
When to use Code 11
Use Code 11 only when the scanner, legacy workflow or receiving specification explicitly names Code 11.
Data and validation rules
Native Code 11 data consists of digits and hyphen. Check-character handling can vary by implementation.
Standards and governance
Code 11 is an established industry symbology rather than a current ISO/IEC barcode standard. Code 11 does not define ownership of the numeric identifier; your business system assigns and interprets the value.
Printing and scanner testing
Use sufficient bar width, maintain quiet zones and verify the final printed symbol with the actual Code 11 scanner configuration.
Common mistakes to avoid
Common errors include unsupported characters, mismatched check-character settings and shrinking narrow bars below reliable print resolution.
How Code 11 compares with related formats
Code 11 is primarily numeric plus hyphen and is usually selected for compatibility. Code 128 supports a much broader character repertoire.
Before you print
- Correct symbology selected
- Identifier ownership confirmed
- Check digit verified
- Quiet zones kept clear
- Strong bar contrast
- Aspect ratio unchanged
- SVG or high-resolution PNG
- Production scanner test
