Frequently Asked Questions
1. Which barcode format should I choose?
CODE128 is the most versatile and supports alphanumeric characters. EAN-13 and UPC-A are standard retail formats used on products. Choose the one required by your inventory or point-of-sale system.
2. Is this tool free and private?
Yes, this Barcode Generator is 100% free. All barcodes are generated locally in your web browser. No data is sent to our servers, ensuring complete privacy.
3. Why do I get an 'Invalid input' error?
Certain barcode formats require specific input. For example, EAN-13 requires exactly 12 numeric digits (the 13th is a checksum calculated automatically). UPC-A requires exactly 11 numeric digits. Ensure your input matches the format's constraints.
4. Can I use these barcodes commercially?
Yes, the generated image is free for commercial use. However, for retail products, you must ensure the underlying number (e.g., UPC or EAN) is officially registered to your company via GS1 to avoid conflicts.
