When to choose Code 128

UPC and EAN codes are fixed retail identifiers registered through GS1. Many businesses also need Code 128 barcodes for internal SKUs, warehouse bins, asset tags, and shipping cartons — codes you define yourself without a global registry.

Code 128 supports variable-length alphanumeric data in a compact symbol, which is why inventory teams search for a code 128 barcode generator when Excel mail-merge or font-based solutions stop scaling.

Bulk Code 128 from a product list

QuickCode reads your CSV, generates a Code 128 image per row, and places it on a label template with human-readable text below — SKU, product name, or custom fields you map. Quantity columns let you expand one line into multiple identical labels for bin stocking.

Because everything runs in a single browser workflow, you avoid exporting PNGs one by one and manually dragging them into label software. One PDF matches your Avery or A4 sheet; print, peel, and apply.

Setup steps

  1. Upload CSV with a column containing Code 128 payload strings.
  2. Map the barcode column and any text fields to show on the label face.
  3. Select Code 128 on the configure step (alongside UPC-A, EAN-13, or QR if needed).
  4. Choose a template — 2×1 works well for narrow shelf labels; 5160 for high-density pages.
  5. Preview, download PDF, and print at 100% scale with no scaling in the print dialog.

Code 128 vs retail barcodes

Use UPC-A or EAN-13 when a retailer or marketplace requires GS1 symbols. Use Code 128 for internal operations where you control the encoding. You can switch symbologies per project without changing tools — see UPC labels and CSV import for related workflows.
