Generate a USPS SCAN Form

A USPS SCAN Form (Shipment Confirmation Acceptance Notice) saves you time at when dropping off packages. 

Instead of scanning each package one by one, you get a single barcode for all your shipments. When USPS scans that barcode, every package on the form receives an official acceptance scan.

Before you generate a SCAN Form

Eligibility

• US sellers only: SCAN Forms work only for domestic USPS shipments. International orders must be scanned one by one.

• Show orders only: You can only generate a SCAN Form for orders from a single show. Each show needs its own form; you can't combine forms from multiple shows. 

Timing

• Same day only: Generate your SCAN Form on the same day you generate labels. Once that day passes, the form can’t be created.

• No do-overs: You can only generate a SCAN Form once. Download the PDF right away after generating. 

Shipment setup

• Not yet shipped: Orders already marked as Shipped in Seller Hub can’t be added.

• One form per shipment: Once a shipment is on a SCAN Form, it can’t be moved.

• Canceled labels: Canceling a label invalidates the SCAN Form it’s on.

Browser tip

• Turn off your pop-up blocker before generating your SCAN Form PDF. 

How to generate a SCAN Form 

1. From whatnot.com, go to the Shipments page in Seller Hub

2. Filter by the show (SCAN is only available for orders from shows)

3. Review your shipments and generate shipping labels for the orders

4. Click Generate USPS SCAN Sheet on the sidebar

5. Download the SCAN form right away (you can't regenerate it later)

Use your SCAN Form at USPS

You can give your SCAN Form to a USPS employee during:

• Pickup: Hand your packages and the SCAN Form to your letter carrier

• Drop-off: Bring your packages and the SCAN Form to the post office and give them to a USPS clerk

Once your barcode is scanned, all included shipments will be accepted at once.

FAQs

Why am I seeing an error when generating a SCAN Form? 

You might see an error like “Could not generate a SCAN sheet” if you’re trying to generate the form after your labels were generated. SCAN Forms must be generated on the same day as your shipping labels. 

If you missed the window, ship without a SCAN Form this time.
