Barcode Generator & Vector Label Maker
Generate scannable Code 128 barcodes for products, inventory SKUs, shipping labels, and ID badges with instant SVG and PNG downloads.
Understanding Barcode Symbologies
One-dimensional (1D) barcodes translate alphanumeric characters into patterns of alternating parallel dark bars and white spaces:
- Code 128: The most versatile 1D barcode format. Supports numbers, letters, and punctuation with an exceptionally compact footprint. Ideal for internal inventory and packaging.
- UPC-A & EAN-13: Fixed-length numeric barcodes (12 or 13 digits) reserved for global retail point-of-sale scanning, administered by GS1.
- Code 39: An older industrial symbology still prevalent in government and automotive supply chains.
Recommended Business Applications
- ✓Warehouse Inventory & SKU Tagging
Generate sequential or custom alphanumeric barcodes for bin locations, pallet tags, and internal stock management systems.
- ✓Retail Packaging & Product Labels
Export vector SVG barcodes to embed directly into Adobe InDesign, Illustrator, or packaging die-lines without pixelation.
- ✓Shipping Tracking & Logistics Manifests
Format tracking numbers and order verification codes for thermal label printers (Zebra, Brother, Dymo).
- ✓Event Tickets, Badges & Wristbands
Encode attendee reference IDs onto conference passes and badges for rapid laser scanner entry check-in.

Frequently Asked Questions
What is Code 128 barcode format?
Code 128 is a high-density linear 1D barcode symbology capable of encoding all 128 ASCII characters (numbers, uppercase and lowercase letters, and punctuation). It is the universal gold standard for logistics, shipping containers, and warehouse inventory control worldwide.
Will these barcodes scan with phone cameras and handheld laser scanners?
Yes! Because the generator strictly adheres to the standard Code 128 specification (including proper quiet zones, start/stop characters, and modulo-103 checksum verification), the generated barcodes scan reliably with any handheld laser scanner, flatbed supermarket scanner, or iOS/Android barcode scanner app.
What is a barcode 'quiet zone'?
The quiet zone is the blank margin on either side of the barcode bars. Barcode scanners require this empty margin (typically 10x the width of the narrowest bar) to detect where the pattern begins and ends.
Can I download the barcode as a vector graphic?
Yes, click 'Download SVG' or 'Copy SVG Markup' to obtain the pure vector representation. Vector files can be scaled to billboard proportions without losing an ounce of sharpness.
