How do I resolve the "Please add a missing phone number on the contact record. Wait for pending changes to be approved, then update address (A7429)" error?

You will want to make sure that you have included a phone number when adding or updating your organization's contact information. You will also need to make sure you have provided a telephone number when updating an existing address on the account.

You will want to use the Updating Contact Information job aid which is found on the VSS Account Maintenance instructions page.
