Delivery Times & Restrictions

Registered Mail typically takes 3-7 business days for delivery. The slower delivery time is due to:
- Enhanced security handling procedures
- Chain-of-custody documentation at each point
- Locked storage requirements during transit
- Manual processing instead of automated sorting
Service Restrictions
- Not available for international letters
- Cannot be combined with Express services
- Available to all US addresses including PO Boxes
- Serves military APO/FPO/DPO addresses
For faster delivery with tracking, consider Priority Mail (typically 2–3 business days after mailing).
