I need to provide each participant in my study with a unique code number as I will be delivering questionnaires to them pre and post an intervention and want to be able to match up their pre and post answers by their code number. I need to give them a code number so that they will be anonymous

For the first (pre)survey, you can assign them random number using external web service(preferred) or random number pipe text in qualtrics, and show this to respondent and ask to memorize for their post survey. Also using contact list trigger update this random value to a contact list.
In the second survey ask respondent for that random number which will be or code. Use authenticator to authenticate the same. Use this random number to compare.
