What is PS 3606?
USPS Form PS 3606 (Certificate of Bulk Mailing — International) is an official document used to prove that a specific quantity of identical mailpieces was presented to the U.S. Postal Service for international delivery.
Unlike standard tracking, this form does not provide evidence that a specific piece of mail was sent to a specific address. Instead, it acts as a verifiable receipt for your total mailing volume. It is highly utilized by e-commerce businesses, subscription box services, and direct mail marketers who need documentation for client billing, compliance, or internal record-keeping.
Important Deadline Note: PS 3606 must be presented to the USPS clerk at the exact time of mailing. You cannot request this certificate retroactively after the mail has been processed.
