Understanding barcode types
A quick guide to the barcode formats supported by this tool and when to use each one for retail, logistics, postal, and inventory use cases.
UPC-A / UPC-E
Standard retail product barcodes used in the US & Canada. UPC-E is a zero-suppressed version of UPC-A for small labels.
EAN-8 / EAN-13
International retail barcodes used worldwide. EAN-13 is the most common; EAN-8 is for small packages with limited space.
Code 39
Alphanumeric barcode popular in logistics, automotive, and defense. Simple, variable length, but lower density than Code 128.
Code 93
A compact, higher-density alternative to Code 39 with an extended character set. Often used where space is limited.
Code 128 (incl. GS1-128)
High-density alphanumeric barcode used in shipping and logistics. GS1-128 carries application identifiers for structured data (GTIN, batch, etc.).
ITF / Interleaved 2 of 5
Numeric-only, compact barcode used for cartons, pallets, and warehouse labeling. Good for high-speed printing.
Codabar
Older numeric barcode used in libraries, blood banks, and some healthcare systems. Easy to print and read.
MSI (Modified Plessey)
Numeric barcode commonly used for inventory and shelf labels. Simple but limited error detection.
Pharmacode
Single-track numeric barcode used in pharmaceutical packaging for internal identification and control.
Postnet / Intelligent Mail (IMb)
Postal barcodes used by postal services for routing and tracking mail; IMb is the USPS Intelligent Mail barcode replacing Postnet.
GS1 DataBar (RSS)
Smaller retail barcodes (coupons, fresh goods) that can encode variable-length data like GTIN, lot, and weight.
