Validation criteria

Hi @Osama , Yes, to allow for 10 digits, you need to change the question type to “text”.

Welcome @esther32,
As @janna explained just above, you can use a text field, with appearance = number and a regex constraint.

As often, the search function of this forum and the Help Center articles can provide help and examples, see e.g.

• Search results for 'phone number' - KoboToolbox Community Forum
• Restricting Text Responses With Regular Expressions — KoboToolbox documentation.

If you don’t succeed, provide an extract or screenshot of your XLSForm, please.
