How do we handle the verification process when doing submissions to search engines and directory sites?

We create an account on behalf of the merchant at each site. More than 90% of sites permit verification by email. In those cases, we complete the verification process ourselves. In a few cases that happen to be very important, such as Google Maps, verification can only take place via a postcard or phone call. Our preferred method is to guide the merchant through phone verification when email verification is not available. End user should take note that in some cases Google will only allow for a postcard to be used for verification.
