Choosing the Right Barcode Format

Code 128 is the most versatile format — it encodes letters, numbers, and symbols, making it ideal for internal inventory systems, shipping labels, and asset tracking. EAN-13 is the international standard for retail products — if you're selling products in stores, you need an official EAN-13 barcode registered with GS1. For sharing URLs, contact info, or text with smartphones, use QR codes which are easier to scan with phone cameras.
