What format do my mobile numbers need to be in?

To ensure your SMS messages are delivered successfully, mobile numbers should be stored in the correct international format whenever possible.

International Number Format

The recommended format is:

[Country Code][Mobile Number]

When converting a domestic mobile number to international format:

  1. Remove the leading 0 (or + if present).
  2. Add the appropriate country code to the beginning of the number.

For example:

  • Australian mobile: 044312312361443123123
  • New Zealand mobile: 022212312364222123123

Using incorrectly formatted numbers may result in messages not being delivered, or in rare cases, being sent to an unintended recipient.

Default Sending Country

Edgility can automatically identify and format mobile numbers based on the country you primarily send messages to.

You can set your Default Sending Country in two places:

  • Settings > Profile & Settings > SMS Settings or
  • The Send SMS page by selecting the country flag in the top-right corner

Your Default Sending Country tells the system which country’s mobile number format should be checked first when processing recipient numbers.

For example, if your Default Sending Country is set to Australia, the platform will first attempt to identify numbers as Australian mobile numbers. If a number does not match the Australian format, the platform will then look for international prefixes and other recognised number formats to determine whether the number belongs to another country.

This setting helps improve the accuracy of number detection, particularly when importing contact lists that contain domestic mobile numbers without country codes.

Tip: For the best results, store mobile numbers in full international format wherever possible, especially if your contact lists contain recipients from multiple countries.


Australia

  • Country Code: 61
  • Mobile Number Length: 9 digits (excluding the leading 0)
  • Domestic Format: 0443123123
  • International Format: 61443123123

New Zealand

  • Country Code: 64
  • Mobile Number Length: Typically 8-9 digits (excluding the leading 0)
  • Domestic Format: 0222123123
  • International Format: 64222123123

United Kingdom

  • Country Code: 44
  • Mobile Number Length: 10 digits (excluding the leading 0)
  • Domestic Format: 0778123123
  • International Format: 44778123123

Best Practice

For maximum delivery reliability:

  • Store mobile numbers in full international format (country code + mobile number)
  • Set your Default Sending Country to match the country you most commonly send SMS messages to
  • Review imported contact lists for any incomplete or incorrectly formatted numbers
  • Avoid mixing formatting styles within the same contact list where possible

By following these guidelines, Edgility can more accurately identify recipient numbers and maximise SMS delivery success.
