Use the USPS Tracking tool at tools.usps.com/go/TrackConfirmAction with the package’s barcode number.

Cheap comes at a cost.

Always run the numbers in the USPS Postage Price Calculator before you decide. Your budget will thank you.

Can Priority Mail take 4 days?

Priority Mail domestic shipments take 1–3 business days; international shipments take 6–10 business days as of 2026.

Is Priority Mail delivered with regular Mail?

Priority Mail travels on the same transportation network as First-Class Mail and other services.

How does international shipping work USPS?

Does Priority Mail give you a tracking number?
