We want to provide a valid input mask for a UK telephone number. Is there a way to properly set that up so user has an idea what values to provide before hand.

thank you

You may try using a Short text field with an Input masking feature as explained here: https://www.jotform.com/help/381-getting-started-with-the-basics-of-input-masking OR you may use the Masked Input widget on the form.

If you need a phone number verification tool, then you may use our Twilio SMS confirmation widget: https://www.jotform.com/widgets/sms-confirmation

Do review and let us know if you have any further questions/concerns.
