Alphanumeric custom validation

Hi all,
I'd like participants to create their own unique ID where I ask them to list their 3-letter initials plus the last 4 digits of their cell phone number plus how many times they have filled out the survey (they can fill it out multiple times). Therefore, a sample code would look like: ABC12341.
How can I set custom validation such that the first 3 entries are letters and the last 5 entries are numbers?

    I haven't used it much myself and I don't know Regex, but you could try Custom Validation with Matches Regex.
