Barcode Generator Frequently Asked Questions

Retail checkout systems require UPC-A in North America (12 numeric digits) and EAN-13 internationally (13 numeric digits). If you sell products in grocery stores or major retail chains, use these formats.
Yes. Select Code 128 or Code 39 to convert text, words, and names into barcodes. Code 128 supports the entire ASCII character set (lowercase, uppercase, numbers, and symbols), making it ideal for custom names and alphanumeric SKUs.
Choose Code 128, type your internal product SKU (such as SHIRT-BLK-M), and keep the human-readable text enabled. You can download the barcode as an SVG or PNG and print it on product tags or inventory bins.
Yes. You can encode your item code and keep the text label visible to display your price underneath the barcode. Retail barcode scanners read the item number, which points to the current price in your store point-of-sale software.
Always download vector SVG for printing on packaging, labels, or thermal printers. SVG files scale to any physical dimension without pixelating or blurring. Use PNG or JPG for websites and spreadsheets.
Common scanning issues include low contrast, missing margins (quiet zones), or printing raster images at low resolution. Always print black bars on a solid white background and preserve at least 10px of blank margin on both sides.
Yes. Export your barcode as an SVG or high-resolution PNG, add it to your label template (such as Avery labels), and print at 100% scale without scaling or fitting to page margins.
UPC-A has 12 digits and is primarily used in the United States and Canada. EAN-13 has 13 digits and is the global retail standard outside North America. Both include a built-in check digit for scan accuracy.
Yes. You can create and download unlimited barcodes for free. There are no watermarks, no usage limits, and no account registrations required.
