Yes! Just use this format when you enter your number in our notification form: [+][country code][subscriber number including area code]. The numbers should have a maximum of fifteen digits. In the UK and many other countries, local dialing requires the addition of a '0' in front of the subscriber number. This is not required in Feedback Genius' notifications form.
A number dialed as 020-7183-8750 in the UK would be formatted as +44-20-718-38750 in Feedback Genius.
