Customs data collection

Due to international regulations we must provide electronic advanced data (a description of package contents and sender/addressee details) for all barcoded items sent to destinations outside Canada. Customs and security authorities use this data at the destination to facilitate clearance of your items. 

Advanced electronic data is mandatory to select destinations for: 

  • Xpresspost™ – USA 
  • Expedited Parcel™ – USA 
  • Xpresspost™ – International (excluding prepaid) 
  • International Parcel (Air and Surface)
  • Tracked Packet™ – USA
  • Tracked Packet™ – International 
  • Small Packet™ – USA (Air) 
  • Small Packet™ – International (Air and Surface) 

How customs data is collected

Shipping tools 

When you create labels using approved shipping tools that we or our partners (such as marketplaces) provide, the required fields will be identified and you must fill out the fields accurately to complete your order.  

At the post office 

You must provide the post office clerk with the mandatory information.  The clerk will record it electronically to allow printing of your shipping label. You’ll significantly reduce the risk of errors and time spent at the post office by completing the online customs form in advance.  

The online customs form will prompt you to complete all mandatory fields and you’ll have the option to: 

  • Save a 2D barcode to your mobile device


  • Print the form

The post office clerk will scan the barcode from your mobile device or printed form which will auto-populate the required information you previously provided, allowing you to complete your transaction quickly. 

We’re providing this information as a convenience only. All of this information is subject to change without notice, and we don't guarantee its accuracy or completeness. It's your responsibility to make sure that you are complying with all applicable requirements when you send or receive international mail items.
