What is Code 128 and why is it used in shipping?

Code 128 is a high-density linear barcode that can encode the full ASCII character set — letters, numbers, and symbols. It is the most widely used barcode in shipping and logistics, appearing on SSCC labels, packing slips, warehouse bins, and carrier labels. Its compact size and broad scanner compatibility make it the standard choice for reference numbers and shipping marks.

When should I use a QR code instead of a barcode?

Use a QR code when you need to encode a URL, a large block of text, or multilingual content. QR codes can store up to 4,296 characters versus around 80 for a typical Code 128 barcode. They can be scanned by any smartphone camera without a dedicated scanner, making them ideal for tracking links, digital packing lists, or shipment portals.

What is EAN-13 and when do I need it?

EAN-13 is the international retail product barcode — the 13-digit code found on consumer goods sold in stores. It consists of 12 digits you supply plus a check digit calculated automatically. You need EAN-13 if you are selling products to retailers or through distribution channels that require it. For shipping references and cargo identification, Code 128 is the more appropriate choice.

What are shipping marks and why should they include a barcode?

Shipping marks are identification labels applied to cargo packages, typically including the shipper and consignee names, a reference or PO number, the package count, and the destination port. Adding a barcode or QR code to shipping marks allows warehouse staff and carriers to scan packages rather than read marks manually, reducing errors and accelerating cargo handling at origin, transshipment, and destination.

Should I download PNG or SVG?

Download PNG for use on printed labels, PDFs, and shipping documents — it is a raster format that works everywhere and prints sharply at standard label sizes. Download SVG if you need to scale the code to any size without quality loss, or if you are placing it in a design tool or label software. For most shipping mark applications, PNG at 3x resolution is sufficient.

Is the content I enter saved anywhere?

No. All encoding happens entirely in your browser — the text or URL you enter never leaves your device. There are no server requests, no accounts, and nothing is stored. The tool works offline once the page has loaded.
