Free Barcode Generator
This free barcode generator creates UPC, EAN, Code 128, QR, Data Matrix and 50+ barcode types. Download as SVG or PNG. No signup, no limits, no watermarks.
Barcode Formats
Barcode formats are standardized ways of encoding product numbers, tracking IDs, URLs, and other data for scanners to read accurately in retail, logistics, industrial, and marketing workflows. Choose a format below for a dedicated generator with format-specific validation, clearer use-case guidance, and the right download workflow for that symbology. UPC and EAN are built for retail checkout, Code 128 is the default for shipping and inventory labels, Data Matrix fits high-density data into very small spaces, and QR Code is optimized for smartphones and consumer scanning. The bulk generator handles repeated label creation from pasted spreadsheet rows, while each dedicated page explains when to use that barcode type, what data it accepts, and how to print or share the finished symbol without wasting labels, packaging space, scan reliability, production time, or reprint costs later.

Which Barcode Type Should You Use?
Choosing the right barcode format depends on what you are labeling, where the product will be sold, and which scanning systems will read it. Linear (1D) barcodes such as UPC-A and EAN-13 are required for retail point-of-sale systems and encode numeric product identifiers recognized by checkout scanners worldwide. Code 128 handles alphanumeric data and is the standard for shipping labels, warehouse inventory, and logistics tracking where letters and numbers need to be encoded together. Two-dimensional (2D) barcodes like QR Code and Data Matrix encode significantly more data in a smaller space -- Data Matrix fits up to 2,335 characters in a symbol as small as 2.5 mm square, making it ideal for marking electronic components and pharmaceutical vials. QR Codes are optimized for consumer scanning with smartphone cameras and support URLs, WiFi credentials, and vCard contact information. The table below maps common business scenarios to the correct barcode symbology.
| Use Case | Format | Why |
|---|---|---|
| Retail products (USA/Canada) | UPC-A | Required by all North American retailers, Amazon FBA |
| Retail products (international) | EAN-13 | Global standard recognized in 100+ countries |
| Shipping labels | Code 128 | Alphanumeric, high-density, industry standard for logistics |
| Shipping cartons (FBA) | ITF-14 | Required for outer cartons containing multiple UPC-labeled items |
| Small parts / electronics | Data Matrix | Fits in tiny spaces, stores more data than linear barcodes |
| Marketing / URLs | QR Code | Scannable by smartphone cameras, widely recognized |
| Batch inventory labels | Bulk generator | Pasted spreadsheet rows -> on-page review and PNG downloads |
Barcode Generator for Amazon FBA Sellers
Amazon FBA (Fulfillment by Amazon) sellers need barcodes at multiple stages of the fulfillment process, and each stage requires a different barcode format with specific technical requirements dictated by Amazon's seller guidelines. For individual product listings, Amazon requires a valid GS1-issued UPC-A barcode (GTIN) that uniquely identifies the product in the global supply chain. This UPC must be purchased from GS1 directly or from an authorized reseller -- Amazon verifies the GS1 registration and may suppress listings using unregistered or recycled UPC numbers. For case-packed shipments where multiple identical units ship in a single carton, Amazon requires ITF-14 barcodes on the outer case to streamline warehouse receiving. FBA prep centers and third-party label printers typically accept both SVG and PDF barcode files, but SVG is preferred because it scales cleanly to any label dimension without quality loss.
Product Labels -- UPC-A
- Required for all new ASIN listings
- Must be a valid GS1-issued GTIN
- 12-digit format with check digit
- Print at minimum 80% magnification
Carton Labels -- ITF-14
- Required for outer shipping cases
- 14-digit format with bearer bars
- Must survive warehouse handling
- Print at 100% on corrugated material
This barcode generator creates both UPC-A and ITF-14 barcodes that meet Amazon's scanning requirements. Download as SVG for crisp printing on any label size.
Frequently Asked Questions
Frequently asked questions about a barcode generator are the quickest way to learn the practical rules behind choosing the right symbology, preparing valid data, and exporting files that print and scan correctly in real workflows. These answers cover the questions most users ask before creating UPC retail labels, Code 128 shipping stickers, QR campaign assets, or Data Matrix part marks, including when you need a real GS1 number, which file format is best for print, and whether Amazon FBA has extra barcode requirements. If you are building product labels, warehouse signs, packaging artwork, or marketing codes, this section gives you the quick operational guidance needed to use the generator correctly, print confidently, avoid wasted labels on the first run, troubleshoot common setup mistakes before production, compare the safest output options, and choose faster defaults.
