Code 39

^B3

Code 39 (ISO/IEC 16388)

An older but widely supported linear barcode encoding 43 characters: uppercase letters (A–Z), digits (0–9), and special characters (-, ., $, /, +, %, space). Code 39 is self-checking and does not require a check digit, though one can be added. Less dense than Code 128 but has excellent compatibility with legacy scanners.

Common Uses

  • Military and government applications (DoD UID)
  • Automotive industry parts tracking
  • Healthcare supply chain
  • Retail product labeling on legacy systems
  • Name badges and access control

Maximum Data Capacity

Variable length — typically 1 to 43 characters
