→ Contact your local post office immediately (critical for same-day resolution):- Call 1-800-275-8777 and request GPS delivery coordinates.

- Cause: USPS may leave packages with neighbors, apartment staff, or alternate recipients.
- Action:
→ Check USPS Delivery Confirmation for signatures/photos.
