A U.S. virtual address is recommended for mailing purposes especially for e-commerce sellers who will receive more mail due to sales tax registrations in states where they create sales tax nexus. A U.S. virtual address service will help when you obtain an EIN, to ensure you receive the IRS letter that is required for a U.S. bank account. You will want a service that not only offers options to scan, and/or forward mail but really understands what time-sensitive documents you are receiving and how they should be handled.  A U.S. address also comes into play when providing your business information to open your new Amazon account. Many times, it is required when you import your goods into the U.S. (importer of record shipping document) or working with a U.S. supplier.
