Which barcode format should I choose for my products?

For standard international retail items, choose EAN-13 (13 digits). For products sold in the United States and Canada, select UPC-A (12 digits). For shipping labels, inventory, internal asset tags, and logistics tracking, Code 128 is the most versatile because it supports all letters, numbers, and symbols.

Can I print a full sheet of barcode stickers on A4 paper?

Yes! Toolchi includes a built-in Printable Sticker Sheet Generator. Click the 'Print Sticker Sheet' button to generate 10 to 32 duplicate labels on a single A4 page, formatted for standard adhesive sticker label sheets.

Will these barcodes scan accurately with laser scanners and smartphone cameras?

Yes. All generated barcodes strictly comply with official GS1 and ISO standards. The exported 300 DPI high-resolution PNG and infinite-resolution vector SVG ensure crisp, razor-sharp lines that scan instantly on optical laser handhelds and mobile barcode scanner apps.

Can I also create QR codes with this tool?

Yes! Simply switch the type to 'QR Code'. You can encode website URLs, Wi-Fi credentials, business contact vCards, phone numbers, or plain text.
