Validation patterns

Validate the input for certain fields using regular expressions

For certain fields, you can specify which input patterns you expect, e.g. a combination of letters and numbers. This allows you to, for example, have ID numbers or flight numbers entered correctly.
You have the full power of regular expressions at your disposal here.

You can find some examples on this page. Simply copy the pattern and paste it into the corresponding field in guestoo.

Disclaimer: Just because we offer these patterns does not mean that you should blindly request this information from your guests. Please make sure that you are allowed to do so.
