What a QR code is

A QR code (Quick Response code) is a type of barcode that can store information including URLs.

Users can scan QR codes with their smartphone to open websites or download apps.

Link to government domains

QR codes on Welsh Government materials should send users to government domain names, for example www.gov.wales.

The Corporate Digital Team must agree a link from a QR code to a non-government domain, contact digital@gov.wales

Track use of QR codes

Use tracked URLs to find out how many users follow the link in a QR code.

Create a tracked URL using Google’s Campaign URL builder.

If you need help, contact digital@gov.wales.

Layout of QR codes

It's essential the code is large enough for easy scanning:

  • for printed materials a minimum size of 2x2 cm, larger codes may be necessary for greater scanning distances
  • for digital screens, a resolution of at least 150x150 pixels depending on the scanning environment.

Ensure there is space around the QR code, known as the quiet zone to ensure accurate scanning. The quiet zone should be at least 4 times the size of a single module (the smallest square within the code).

QR codes and security

The National Cyber Security Centre says the majority of QR code-related fraud:

  • tends to happen in open space, for example stations and car parks
  • involves social engineering

Consider where QR codes are going to be placed and do not use them for file downloads. 

Get more advice on QR codes from the National Cyber Security Centre.

Consider a short URL

Using a short URL instead of or alongside a QR code may be preferable. For example, if the user is unable to scan the QR code they can use the short URL. Follow the guidance on short URLs.

Create or request a QR code

Create a QR code using the free QR code generator from Adobe.
