If you ask respondents for their phone number, you can have Ethnio automatically detect the country code and format their number properly in any screener (intercept or link):
If they type a number with or without the + symbol, the automatic phone number validation will try to add the right country code. This works at about 95% accuracy, meaning some countries and networks might not be detected properly. Respondents can always use the dropdown to override the automatic location detection.
You can turn this option on from screeners >> questions >> phone >> options and then turn the Validation phone number toggle to on.
