How it works: Most versatile barcode symbology that can encode the full ASCII 128 character set. Uses three character sets (A, B, C) to optimize encoding density. Includes a check digit for error detection.
Best for: Shipping labels, inventory management, general-purpose applications
Example: ABC123, SHIP-2024, Order#12345
How it works: 13-digit international retail product identifier. First 2-3 digits represent country code, next 4-5 digits are manufacturer code, followed by product code, and ends with a check digit calculated using modulo 10.
Best for: Retail products, books (ISBN-13), international commerce
Example: 5901234123457 (must be exactly 13 numeric digits)
How it works: 12-digit North American retail standard. First digit is number system, next 5 digits identify manufacturer, following 5 digits identify product, and last digit is a check digit.
Best for: US/Canada retail products, grocery items, consumer goods
Example: 012345678905 (must be exactly 12 numeric digits)
How it works: Discrete (self-checking) alphanumeric barcode. Each character is represented by 9 elements (5 bars and 4 spaces), where 3 are wide. Includes start/stop characters (*). No check digit required by default.
Best for: Automotive, defense, healthcare ID badges, asset tracking
Example: ABC-123, PART$456, ID+789 (supports: 0-9, A-Z, and -.$/ +%)
How it works: 14-digit code used for shipping containers. Encodes data by interleaving pairs of digits into bars and spaces. Always has even number of digits. First digit is packaging indicator, next 12 are GTIN, last is check digit.
Best for: Carton labeling, shipping containers, wholesale distribution
Example: 12345678901231 (must be exactly 14 numeric digits)
How it works: Numeric-only barcode developed by MSI Data Corporation. Each digit is encoded with 4 bars, uses start/stop patterns. Various check digit algorithms available (Mod 10, Mod 11, or both).
Best for: Inventory control, warehouse shelving, marking storage containers
Example: 1234567890 (numeric digits only)
How it works: Pharmaceutical binary code that encodes integers from 3 to 131070. Uses only 2 bar widths (narrow and wide). Read from right to left. Data encoded as binary using bar widths and spaces.
Best for: Pharmaceutical packaging control, medication tracking in manufacturing
Example: 1234, 5678, 131070 (numeric: 3 to 131070)
💡Pro Tip: For maximum compatibility and flexibility, use CODE128. For retail products that need official registration, obtain proper EAN13 or UPC codes from GS1. For internal inventory and asset tracking, CODE39 offers good readability with simple scanners.
