Phone question formatting & validation ☎️
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):
Validation helps ensure accurate responses in your screener. There are three validation states:
Invalid (Red): No entry or an incorrect input will turn red, preventing the respondent from proceeding.
Partial Validation (Orange if not a required question): If you've enabled validation, but not made this a required question, we show an orange warning for malformed phone number according to each country (e.g., an invalid number) but does not block progress.
- Full Validation (Green): A valid entry is confirmed with a green checkmark and no highlighted color.
These indicators help guide respondents to provide accurate information while allowing flexibility when needed.
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.
