Final answer:
The medical office may use Registered Mail or Certified Mail instead of Signature Confirmation for secure delivery of important documents.
Step-by-step explanation:
The medical office may use various methods instead of Signature Confirmation to ensure secure delivery and receipt of important documents. One common alternative is Registered Mail, which requires recipients to sign for the package upon delivery. Another method is Certified Mail, which also requires a recipient's signature and provides proof of mailing and delivery.
Registered Mail is often used for confidential or sensitive documents, such as medical records or legal papers. It provides an extra layer of security and tracking capabilities, ensuring that the documents reach their intended recipient.
Certified Mail, on the other hand, is commonly used for important business correspondence, such as contracts or important notices. It provides proof of mailing and can be tracked through the USPS website.
