It is your responsibility to make sure all of your shipments are properly addressed to your recipients. Double-check that the address information is correct and complete before and after you create and purchase your postage. Incorrect addresses may be automatically overwritten by the postage provider even if you bypass address verification. Most often this is the result of an incorrect zip code. If you choose not to use the verified address, we recommend you review your postage labels after printing your postage to confirm the address.

Along with providing accurate shipping details, it is equally important to format the delivery address to the specifications required by the country you are shipping to. Many postal carriers stipulate that the recipient name, street address, postal code, and country are written in capitals with no abbreviations. For the best results, we recommend adhering to the guidelines outlined by the destination’s local postal service.


Depending on the carrier and the postage type, important details may be left off of the label for long addresses. In these cases, you may need to use the second address line or to shorten the address using an appropriate abbreviation. If you're not sure about using abbreviations you can check this list to see if they will be accepted in addresses.

Avoid including details that are not important to the delivery of the shipment to the address fields. This includes descriptions of the shipment contents or personal messages. Doing so may impact the deliverability of your shipment. However, do include apartment and suite numbers as well as the directional abbreviations for street addresses when appropriate (i.e. NE, W, etc.). Forgetting these may render your shipment undeliverable!

International Addresses

If you ship internationally, it's also important to keep in mind that each country may have a different addressing format. A recipient phone number will be required for all shipments to the European Union (EU) as customs may attempt to notify the recipient of any outstanding duties or taxes. And in some countries, the carrier may contact you via email in order to confirm details required for the delivery. You can find the specifics of addressing based on the recipient's country on the Universal Postal Union's (UPU) website

Canadian Addressing Format

  • Canadian addresses are formatted differently for street addresses, postal boxes, military addresses, etc. In general an address must contain the addressee, the municipality, the province/territory and the postal code.
  • Postal box addresses should include the postal box number and the station number on the second last line of the address. Additional delivery information such as a street address can be included above this line.
  • Ideally, the address should be written in capital letters and punctuation should not be used unless it is a part of a proper name (i.e. ST. JOHN'S). Accents are not considered to be punctuation. 
  • The symbols # and no should be avoided.
  • There must be two spaces between the province abbreviation and the postal code. 

For more information about Canadian addressing visit the Canada Post website and check out their tool for finding a postal code.

Character Limits for Address

There can be a great deal of variation in addressing formats between destinations. Add to that the physical limitations for label sizes and you end up with character limits on certain address fields.
