Capturing unique variable using Google Analytics tags

Hi all,


Thanks in advance for any help you can offer on this.


I'm currently working for a loan company and implementing Google Analytics Goals to track our activity. There's roughly 8 Steps to the application that we will be tracking.


On Step 3 of the application (after the complete sign up) they are assigned a unique customer id by our database. I've used DoubleClick tracking in the past and know it is possible to capture that variable using those floodlights. Is it possible to do a similar thing with Google Analytics?


We are implementing analytics code and events through Google Tag Manager - will this impact how this variable is captured?


I've read a bit on how the data layer works, but I have very little coding experience so just wanted to check with you guys.


Kind regards,

Hi Brendan,

You can use custom dimensions to collect data that is not tracked automatically by GA:

Please check the document below about setting up custom dimensions using GTM:

You can also use your unique user id for cross device tracking using the User ID feature:

Here are the instructions for GTM:

Hope this helps, let me know if you have questions.
