Supported Barcode Types

We support the most popular symbologies used worldwide:

1. Code 128 (Recommended)

The most versatile barcode. It supports letters, numbers, and symbols. Perfect for internal tracking, shipping labels, and ID cards.

2. EAN-13

The standard retail barcode used in Europe and most of the world (except USA/Canada). It encodes 13 digits and is found on almost every consumer product.

3. UPC (Universal Product Code)

The standard retail barcode for North America (USA & Canada). It encodes 12 numeric digits.

4. Code 39

An older, robust format often used in automotive and defense industries. It supports numbers and uppercase letters but takes up more space than Code 128.

How to Generate a Barcode

Creating a scan-ready code takes just a few clicks:

1. Select Type

Choose the barcode format that fits your needs. If you aren't sure, Code 128 is usually the safest bet for general use.

2. Enter Data

Type your alphanumeric code (e.g., "PROD-001") or numeric ID. The preview updates instantly. If the data is invalid for the selected type (e.g., letters in EAN-13), we will alert you.

3. Customize

Adjust the bar color and background to fit your design. Ensure there is high contrast (dark bars on light background) for scannability.

4. Download

Click "Download PNG" for a high-quality image or "Download PDF" for a vector file that remains sharp at any print size.

Tips for Printing Barcodes

To ensure your barcodes scan correctly every time:

• Keep it High Contrast: Black on white is the gold standard. Avoid red bars on green backgrounds, as scanners can't read them.
• Don't Scale Too Small: If the bars get too thin or close together, standard scanners might fail. Keep the size reasonable.
• Quiet Zone: Leave some empty white space around the barcode. Do not print text or borders flush against the bars.
