How to generate a barcode

Which barcode format should you choose?
| Format | Use it for |

| Code 128 | Your own stock, assets and shelf labels |
| EAN-13 | Retail products in Pakistan and most of the world |
| UPC-A | Retail products in the US and Canada |

Do you need to buy a barcode number?
Not for your own stock. Make up any code and use Code 128. For products that a shop or marketplace will scan, the number should be registered through GS1, which has a national office in Pakistan. Ask your retailer what they accept before you print packaging.

Open the QR Code Generator, paste your link or WiFi details and download the image. Test it with your phone before you print it.
Frequently asked questions
Do these codes expire?
No. A barcode or a QR code made here stores your data directly in the image, so it keeps working. A QR code stops being useful only if the link inside it stops working.
Can my phone read a barcode?
Phones read QR codes with the camera, while plain barcodes often need a scanning app.
Can a QR code replace a barcode at a shop till?
Only if the shop scanner and its system support it, so ask the shop first.
