Patterns for e-mail address and phone numbers


do you have any suggestions on how to specify patterns for e-mail addresses and phone numbers?

Can I make a requirement that the e-mail address must include an @ for example without knowing how many characters come before and after it?

Since the survey will be completed in different countries, is there a way to allow for enough flexibility for different phone number formats but still imposing some restrictions, e.g. requiring numbers.

Thank you for your help,

Hello Michelle,

when you create a question mentioning email, such as “What is your email?” the Survey Solutions Designer will automatically advise you to use a certain function for validating the email. Check out the warnings page.

For phones see the example in checking text format in the public questionnaire
