What is the highest classification level that can be transmitted using USPS First Class Mail?

• A. Confidential
• B. Top Secret
• C. Unclassified
• D. Secret

Answer: (A)

The key idea is how classification levels determine the mailing channel. USPS First Class Mail is the standard service for ordinary mail and can carry documents that are Unclassified or Confidential, as long as they are properly secured and marked. Content at Secret or Top Secret requires stronger, more secure handling than First Class provides, such as Registered Mail or other controlled channels. Unclassified is a lower level than Confidential, so it isn’t the highest that First Class can handle. Therefore, Confidential is the highest classification that can be transmitted using USPS First Class Mail.
