Barcode Data
About Barcode Generation
Barcodes are machine-readable representations of data, typically representing numbers or alphanumeric strings.

Code 128:
• High-density barcode supporting all 128 ASCII characters.
• Widely used in shipping, inventory, and retail industries.
• This tool uses a simplified implementation of Code 128 Set B.

High-Quality Code 128 Barcode Generation

A Barcode is a visual, machine-readable representation of data. Code 128 is an industry-standard, high-density linear barcode symbology capable of encoding all 128 characters of the ASCII set. It is widely preferred in logistics, retail, and supply chain management because it can pack significant amounts of data into a small, reliable space.

Our Online Barcode Generator provides a fast, free way to create these barcodes for your asset tags, labels, or digital tracking needs.

Why Choose Code 128 (Set B)?

We use Code 128 Set B, which is the most versatile variant for modern use. It supports:

  • Uppercase Letters (A-Z)
  • Lowercase Letters (a-z)
  • Numbers (0-9)
  • Standard Symbols (e.g., -, ., $, /, +, %, and space)

Professional Generator Features

1. Sharp SVG Vector Graphics

Unlike generators that output low-quality images (like PNG or JPEG), our tool creates SVG (Scalable Vector Graphics).

  • Infinite Scaling: Your barcode will stay perfectly sharp whether it's on a small asset tag or a giant shipping crate.
  • Crisp Printing: Guarantees high scan rates by providing the perfect contrast required by laser and CMOS scanners.

2. Live Browser Rendering

All barcodes are generated locally in your browser. This means:

  • Privacy: Your data never leaves your computer or gets stored on a server.
  • Speed: See the barcode update instantly as you type each character.

3. Industry Presets

Quickly generate standard patterns for:

  • Serial Numbers (e.g., SN-102938)
  • Product Codes (e.g., PROD-001)
  • Asset Tags (e.g., ASSET-2024)

How to Use the Barcode Generator

  1. Enter Your Data: Type the code you want to visualize (e.g., ITEM-1234) into the input box.
  2. Click Generate: The barcode will appear instantly below the button.
  3. Download/Use: Use the generated SVG for your labeling software or design projects.

Common Use Cases

  • Inventory Management: Label stock items with unique IDs for quick checkout and stock-taking.
  • Office Assets: Track laptops, printers, and furniture by sticking a barcode tag on each item.
  • Retail Labels: Create shelf tags or product price stickers.
  • Logistics: Generate tracking numbers for internal package routing.
  • Identity Cards: Include a scannable member ID on employee or student badges.

Frequently Asked Questions

Can this barcode be scanned by a phone?

Yes! Modern smartphone cameras and dedicated barcode scanning apps are fully compatible with Code 128.

Is there a character limit?

While Code 128 is high-density, very long strings will result in a very wide barcode that might be difficult to scan with small handheld devices. We recommend keeping your codes under 30 characters for best results.

Does it cost anything?

No. Our Barcode Generator is 100% free with no registration required.
