We don't handle telephone verifications for citation sites that require it (there are just six sites in our database that require phone verification).
Phone verification requires co-ordination between BrightLocal and the business / client to organize phone calls and share verification codes. BrightLocal would need to have direct contact with the business / client to make it work smoothly, and a lot of our agency customers prefer us to operate as an invisible partner in the background.
We take care of the submission up to the phone verification point (i.e. we create an account on the site and submit business details). Everything is set up for the phone verification step to occur — the details that the customer needs in order to complete the phone verification step are passed on. We put all these details in the 'notes' next to the citation site in the Citation Builder campaign report.
