How to use Regex set up an unique survey ID?

G
Hello community!

I need to set up a validation of a Text entry box for a specific format. I ask participants to create their own unique survey ID for a longitude study. The requirements of the participant ID is below:

"Using last 4 digits of your mobile number PLUS initial of your mother’s maiden name"

Example: (mobile number: 04051314516, mother’s maiden name: Julie Smith) => 4516JS

I want to make sure people put exactly 4 digits plus 2 characters in to the text entry box. Anyone know how to do this?

Hi Shashi,

Thank you for the reply.

As I am new to Qualtrics, could you please clarify how to insert the regex that you provided into the survey setting?

Go to custom validation -> in the drop down select "Matches regex" -> and in the text entry box paste the regex.
