Registered and Certified Mail - S-1 Procedural Page

Role and responsibility

The Postal Officer or designated unit mail clerk processes registered and certified mail per USPS Domestic Mail Manual and MCO 5110.4BMCO 5110.4B. The OMPF clerk uses registered mail for OMPF Field Folder transfers per MCO P1070.12KMCO P1070.12K Chapter 3. The sender signs the accountability log. The receiving Marine signs the return receipt. The Postal Officer maintains the accountability chain.

Source documents flow from the mail requiring registered or certified handling (OMPF Field Folder, sensitive correspondence, court documents, legal action notices, classified material with appropriate authorization), the USPS DMM and IMM rules, the sender signature, the recipient signature, and the return receipt. Outputs include the executed registered or certified mail processing, the documented accountability chain, the captured signatures, the return receipt on file, and the audit trail.

Per USPS DMM, registered mail provides the highest level of mail security with documented chain of custody from acceptance to delivery. Per USPS DMM, certified mail provides delivery confirmation with signature on receipt. Per MCO P1070.12K Chapter 2, OMPF Field Folder transfers use registered mail or equivalent secure routing.

Trigger events

• OMPF Field Folder transfer requires registered routing.
• Sensitive correspondence requires certified handling.
• Court order or legal action notice routing.
• Inbound registered or certified mail receipt.
• Annual accountability audit cycle.
• USPS rule update on registered or certified mail.

Processing workflow

1. Identify the mail. The sender identifies the document requiring registered or certified handling.
2. Select registered versus certified. Per USPS DMM, the security and accountability need drives the choice:
   • Registered mail for highest security (OMPF Field Folder, sensitive personnel records, classified material with appropriate authorization).
   • Certified mail for proof of delivery without highest-security accountability (legal notices, formal correspondence).
3. Apply USPS DMM handling. Per the USPS DMM registered or certified mail procedures, the Postal Officer processes the mail at the MPO or USPS facility.
4. Capture sender signature on accountability. The sender signs the accountability log on dispatch.
5. Process inbound registered or certified mail receipt. The receiving unit signs the return receipt on receipt.
6. Maintain accountability log. Per USPS DMM and MCO 5110.4BMCO 5110.4B, the log documents every transfer.
7. Verify chain of custody at every transfer. Each transfer captures the signature of the receiving party.
8. File the return receipt. The sender retains the return receipt as proof of delivery.
9. Run annual accountability audit. The Postal Officer audits the accountability log against the USPS records.
10. Apply to OMPF Field Folder transfers. Per MCO P1070.12KMCO P1070.12K Chapter 3, OMPF Field Folder transfers use registered or equivalent secure routing.
