Find your parcel

If US Customs is holding a parcel addressed to you, they mailed you a notice. Enter the tracking number from that notice and we'll look it up.

Where do I find this?

It's on the notice from CBP — often labelled Package Number (box 6) on Form 3509. It's also the tracking number the sender gave you.
