What this does
The phone number field maps to Airtable’s Phone Number field type. It includes a country code selector, automatic country detection, and format validation against country-specific phone number patterns.Settings reference
| Setting | Description |
|---|---|
| Placeholder text | Hint text shown when the field is empty. |
| Default value | Phone number pre-filled when the form loads. |
| Default country | The country code pre-selected in the country dropdown. Enter a 2-letter country code (e.g., US, GB, AU, CA, NG). |
| Show country selector | Display a country code dropdown before the phone input so respondents can select their country’s dial code. |
| Validate phone format | Validate that the number matches the expected format for the selected country. Shows an error with an example number if the format is wrong. |
| Auto-detect country | Pre-select the respondent’s country based on their IP-derived location. Respondents can still change it manually. |
| Minimum characters | Minimum character count required. |
| Maximum characters | Maximum character count allowed. |
How country detection works
When Auto-detect country is enabled, Filla uses the respondent’s IP address to determine their likely country and pre-selects the matching dial code in the country selector. The respondent can override this by selecting a different country from the dropdown.Format validation
When Validate phone format is enabled, Filla checks the entered number against the expected format for the selected country (powered by libphonenumber). If the format is wrong, the error message includes an example of a valid number for that country. Example: For the US, a valid format is(555) 555-5555. For the UK, 07700 900000. The validator checks these formats on blur (when the respondent leaves the field).
Common questions
Can I require a specific country's format?
Can I require a specific country's format?
Set the Default country and optionally hide the country selector by turning off Show country selector. With a fixed country selected and format validation on, only numbers in that country’s format will be accepted.
How is the phone number stored in Airtable?
How is the phone number stored in Airtable?
The number is stored as entered, including the country dial code if the country selector is shown. For example:
+1 555-555-5555.Does format validation block submission?
Does format validation block submission?
Yes. If format validation is enabled and the number doesn’t match the expected pattern, the respondent sees an error and cannot submit until the number is corrected or the country is changed.
