Well according to the post office package intercept is a feature that allows the sender to redirect any package, letter or flat that hasn’t been delivered.
USPS Package Intercept
What It Is
USPS Package Intercept® lets you redirect a domestic shipment that hasn’t been delivered or released for delivery. It’s available for packages, letters, and flats with a tracking or extra services barcode.
You can also stop mail and packages at a Post Office™ as a Hold For Pickup. You can even request to have them redirected as Priority Mail® back to your address.
Commercial Customers
If you have a Centralized Account Payment System (CAPS) account, you can register online at the Business Customer Gateway to make your request and pay applicable fees.
How It Works
Verify that your shipment is eligible for Package Intercept.
If eligible, you can submit your request online after logging in with your USPS.com account.
After submitting your request, you’ll be provided an estimated total (intercept fee plus estimated Priority Mail postage, if applicable). We will then attempt to intercept and redirect the shipment.
If the package is intercepted, your credit card will be charged the $13.45 Package Intercept fee plus any applicable postage. If the actual postage is greater than estimated, any additional postage will be charged accordingly.
With Package Intercept, you can redirect mail or packages to the sender. Your local Post Office can also hold for pickup.
Restrictions
Customers will not be charged if the shipment was not intercepted. If successfully intercepted, the non-refundable Package Intercept fee is applied to each intercept request.
