Stuck or normal?
Normal here: 1 to 7 days, mostly customs time, which USPS does not control.
Act if: no new scan for 10 business days. Weekends and federal holidays don't count.
USPS lets you start a Missing Mail search 7 days after mailing, even if this plant's normal time hasn't passed.
At peak and after rule changes on imports, customs queues can add a week or more. These are rules of thumb from how USPS's network works, not a USPS promise. How we set them.
What to do if your package is stuck here
- Wait until there's been no new scan for 10 business days. USPS often skips scans between plants, so a quiet "In Transit to Next Facility" is usually fine.
- Submit a Help Request Form on usps.com. It goes to your local post office, and either you or the sender can file it. USPS tracking FAQ
- Still nothing? Start a Missing Mail search. You can file it 7 days after the mailing date, even if this plant's normal time hasn't passed. USPS Missing Mail
- If it was insured (Priority Mail and Ground Advantage include some coverage), file a claim within 60 days of mailing. USPS claims
