Who Called My Phone?

How to figure out an international phone number?

I was given a number by an acquaintance to call him and he never got a chance to answer my last e-mail asking him where he is so I can add the country codes. How do I figure that part out? Here are the first eight numbers and the rest I am blocking to safeguard privacy. :+4470 1422 XXXX.. I tried reverse ;lookup online services and they can’t seem to help either.
Yes, that I know but which country’s phone number is this?

Dial 011, then the numbers you provide.
