The accepted format for the value you can add to the mobile phone field for your contacts will be different according to the SMS channel configuration that is used in your project. There are 2 possible configurations:
- E.164 format
- Local format for a specific country
Please ask our team which configuration is used in your project.
| If your recipient's phone number is a landline, the text message will be in error for that contact and will not be delivered. You must use a mobile phone number. |
E.164 Format
The following table lists the countries whose numbers are compatible with sending SMS messages. These numbers will automatically be converted to E.164 format (normalized number), allowing SMS messages to be correctly delivered to subscribers.
The E.164 format is as follows:

You can download the list of country codes at the end of this article.
Local Format
This format accepts a number in a local format defined by the SMS configuration of the project. This format will be automatically converted to E.164 format by the system. When this format is used in your project configurations, you can add the contact numbers using different formats.
The phone number can start with the country code (e.g., "01" or "01") or not. You can use hyphens, slashes or parentheses. When converting, the system ignores spaces and any characters that are not numbers. In short, the conversion system is quite flexible.
