Claim Your P.O. Box Parcel Faster & Easier
Don't let your package get returned to sender. Whether you're picking it up yourself or authorizing a third party, prepare your USPS Parcel Pickup Notice online in minutes.
What is PS 3908-S?
The PS 3908-S (P.O. Box Parcel Pickup Notice) is an official form utilized by the U.S. Postal Service. You typically encounter this notice inside your P.O. Box when a received package is too large to fit in your box, requires a signature upon delivery, or has outstanding postage due.
While USPS provides the physical slip, digitizing your response allows you to cleanly pre-fill authorization details—especially critical if you are sending an employee, family member, or authorized agent to the retail counter to retrieve the parcel on your behalf. Note: Packages are generally held for 15 days before being returned to the sender.

Detailed Walkthrough: Avoiding Common Mistakes
1. Recipient & Box Information
Ensure the P.O. Box number matches exactly what is on your official USPS rental agreement. A mismatch here can cause clerks to refuse the package release.
2. Tracking & Article Numbers
If your physical notice has an article number written on it, transcribe it perfectly. This is how the clerk locates your package in the back room among hundreds of others.
3. Third-Party Authorization
If someone else is picking up your package, you must sign the authorization section. The person picking up the package will also need to present their own valid government-issued photo ID.
