Generate random mobile number – Virtuoso

The Random/GetMobileNumber extension generates a random 10-digit integer.

This is useful when a journey needs a random mobile-number-like value for test data entry or validation steps.

Parameters:

No input parameter is required. The source code sets len internally to 10;

Note: Although the purpose mentions len, the provided source code does not expose len as an extension input. It is hardcoded as 10.

NLP usage

Use the extension in a journey by calling Random/GetMobileNumber with the execute command. This extension does not require values to be passed with as inputName.

Note: The returned value is generated using JavaScript Math.random(), so each execution can return a different 10-digit number.

execute "Random/GetMobileNumber" returning $mobileNumber

execute "Random/GetMobileNumber" returning $randomPhoneNumber

The extension can store the generated value directly in a Virtuoso variable.

execute "Random/GetMobileNumber" returning $mobileNumber

execute "Random/GetMobileNumber" returning $mobileNumber

Example output:

9876543210

This extension does not require any external resource.

The extension should be configured as:

Run asynchronously: No
Scope: Global

Limitation: The script always generates a 10-digit integer because len is hardcoded in the source. It does not validate country-specific mobile number rules, prefixes, uniqueness, or formatting. The value is produced with Math.random(), so it is suitable for simple test data generation but not for secure or guaranteed-unique identifiers.
