Hi Ilan Bloemhof, By using Moz Local you can push out updates to all online directories with the new phone number. The important thing to remember about using Moz Local is that the information needs to match what it shown on your Google My Business profile, so the first step would be going into Google+ and making sure anything that has changed is updated. Once this is done, it will take about a week or so for Moz to register the changes, but once it does you can start pushing this information out to the online directories. Hope this helps!
