Understanding E.164 Phone Number Format in Zendesk Talk
What is the E.164 phone number format used by Zendesk Talk?
Zendesk Talk uses the E.164 format for phone numbers, which is an international standard. This format allows for a maximum of fifteen digits and is structured as [+][country code][subscriber number including area code]. For example, a US number would look like +16175551212.
Using the E.164 format ensures that phone numbers are recognized correctly by Zendesk systems, which route through Twilio. It's important to use this format to avoid issues with saving numbers to user profiles, especially if the Validate user phone numbers setting is enabled.
