Namespace: Zenoph.SMSLib
Assembly: Zenoph.SMSLib (in Zenoph.SMSLib.dll) Version: 2015.9.30.0 (2015.09.30.0)
public string parsePhoneNumber(
	string phonenum


Type: SystemString
The phone number to be parsed into specific international format.

Return Value

Type: String
Returns the phone number in international format for submission. If the phone number is invalid or not allowed on user routes, the return value will be null.
Exception Thrown if authentication has not been performed for user routes to be loaded or when phonenum is invalid.

The method parses the phone number and returns it in a specific international format. For example, if the phone number is given as +231xxxxxxxxx or 0023320xxxxxxx, the method will parse the phone number and return it in the form 231xxxxxxxxx or 23320xxxxxx. Hence, phone numbers can be specified with the leading +, 00, or without them.

Phone numbers can also be specified in local format with or without the leading zero (0). For example, 0246xxxxxx, 246xxxxxx In this case, the method will automatically format the phone numbers in international format by choosing the default international dial code set to be used. If no international dial code has been set for the current session, the default international dial code set for user account will be prepended to phone numbers given in local number format.

The method also ensures that phone numbers passed to it are valid and that they are allowed on user routes. If a phone number is invalid or not allowed on user routes, the method returns null.


The following code demonstrates the capabilities of this method.

             * that null can be returned if the number is invalid or not allowed.
             * Assuming the default international dial code set is +233.
             * In each case, the return must be checked whether is null or not before being added.
             * If there is the need to check the return value before adding the phone number,
             * the return value can be saved and the check being done

             * Or we can add the destination on the fly. If the return value is null, the throwing of
             * Exception will be ignored since the second argument to addRecipient is true.
            sms.addRecipient(sms.parsePhoneNumber("249888888"), true);  // will add 233249888888 if route activated.
