Phone Number Fields

Learn about Phone Number fields in Noloco tables

Phone Number fields are structured to hold contact telephone numbers consisting of the country code and the number itself. Phone numbers are stored in the E.164 standard format.

For example, if a user chooses "United States" and enters [phone] then the stored value will be "[phone]".

Components

Phone Number fields include:

• Country Code: Automatically selected dropdown

• Phone Number: The actual phone number

• Extension (optional): Can be toggled on/off

Format and Storage

All phone numbers are stored in E.164 international format, which:

• Starts with a '+' sign

• Includes the country code

• Contains only digits after the country code

• Has no spaces, hyphens, or other formatting characters

Configuration Options
