Phone number field type
concept brazil Updated Sep 10, 2026 1 min read c_UsePhoneNumberFields.md
The E.164 phone number standard ensures that all necessary information for a phone number is included and properly formatted to successfully route an international call over a territory's public telephone network.
When a user enters a phone number, it is received and stored as a string of numbers. An E.164 phone number field automatically formats and validates the numbers so that they are E.164-compliant when displayed as local and international numbers. The E.164 phone number field type does not replace the phone field type.
An E.164 phone number field displays:
- [Optional] A choice list for the phone number territory.
- [Always] An input box for entering phone numbers.
- [By Default] A red underline when a phone number does not match the format for the selected phone territory and cannot be saved.
- [Optional] A green underline when a phone number does not match the format for the selected phone territory but can be saved with Other / Unknown as the territory.
