Multiple tracking codes on web pages

You can install multiple instances of the Google Analytics tracking code on your web pages to send data to multiple properties in your account.

Not all configurations are supported. You can, for example, install multiple instances of the Universal Analytics tracking code (analytics.js) on your web pages but only one instance of the Classic Analytics code (ga.js). Multiple instances of ga.js might result in inaccurate data collection, processing or reporting. You can, however, install one or more instances of analytics.js on web pages that also have a single instance of ga.js.

Using multiple tracking codes might be useful if users with access to different properties need to see data from the same website, or if you have multiple versions of a website. You might, for example, want to collect data from using one instance of analytics.js, collect data from in another instance of analytics.js, and use a third instance of analytics.js on both websites to see the aggregate data.
