Different USPS Statuses Meaning

While scrolling through your shipment’s tracking information, you will likely see different messages regarding your item’s delivery status. The following sections explain what these messages mean.

What Does “In Transit” Mean in the U.S. Mail Service?

Your item is “in transit” when the courier has picked up and scanned your parcel and sent it to your recipient.

Your shipment can get delayed if it is in transit for an extended time. This delay can happen because of adverse road conditions, unfavorable weather, or poor deliverability at the recipient’s location.

What Does “Out for Delivery” Mean in the U.S. Mail Service?

This message means your parcel has left the courier’s facility and is going to your recipient’s address. This status should update to “delivered” after the postal worker successfully delivers your package to your recipient.

What Does “Delivered” Mean in the U.S. Mail Service?

The “delivered” message means the courier has delivered your package and the recipient has accepted it. The tracking information should also indicate the delivery date and time.

What Does “Return to Sender” Mean?

If you are the recipient, “return to sender” means the courier is returning your package to the shipper. You may incur taxes or duties for the return if you are the mailer.

Inbound Out of Customs” Meaning

This status means U.S. Customs has cleared and released your package, which should be heading toward your recipient.

If the message says “outbound” instead, your package has likely passed customs inspection and is on its way to the destination country.

Other Tracking Statuses

Other status messages you may encounter when checking your package’s tracking information are as follows:

  • Missed “in transit” pickup scan: The package routed internationally is stuck “in transit” for an extended time and then instantly updates to “delivered.”
  • Damaged in transit: The item got damaged while in transit. You can consider filing a claim to receive compensation.
  • Uncontrollable customs delay: Your international package is stuck at customs for some reason, such as your recipient having to pay outstanding duties or taxes.

  • Package not scanned at intermediate stops due to unavoidable situations
  • Delay on the part of the carrier
  • Unscannable or broken barcode

“I’ve Received My Packages, but Still, U.S. Mail Service Tracking Is Not Updating”

If you are the recipient, receiving your package without its tracking information updating is possible, especially during a holiday package delivery rush. USPS can skip scanning to handle the demand increase in these situations.

In other words, USPS may forego scanning if doing so can help move the packages quicker.
