Find suppliers of address validation products and services

Canada Post recognizes the address validation and correction software of a number of vendors who supply products and services to clean address databases and confirm address validity. When you work with a recognized vendor, you can feel confident that they are able to check and correct your address list according to Canada Post address validation requirements.

How does a vendor get recognized?

Through our Software Evaluation and Recognition Program (SERP), we evaluate vendors’ address validation and correction software based on their ability to process a batch of addresses and identify:

  • Addresses that are valid.
  • Addresses that are invalid, but can be fixed.
  • Addresses that are invalid and cannot be fixed.

SERP vendors must also be able to produce a statement of accuracy, showing an accuracy score for the batch they processed. The statement of accuracy and its score are used when placing an order for Incentive Lettermail, Personalized Mail™ (Addressed Admail™) or Publications Mail.

Once a software vendor passes our evaluation, they license our address data for use within their software.

Why clean my address list?

Using Canada Post Data Management Services or a recognized vendor to clean your address database before sending a mailing will improve address quality and reduce undeliverable mail.

  • Save money and improve your return on investment by reducing undeliverable mail.
  • Receive the best postage rates when your address validation score is 95% or better.

Canada Post recognizes, but does not warrant, address validation and correction software on this list. These packages were evaluated by the Software Evaluation and Recognition Program (SERP) using the criteria established by Canada Post as of August 2013. They will be considered valid until January 2022.

The program does not evaluate any subjective criteria such as speed of operation, user friendliness or customer support. This List of Recognized Software details the software packages that have met or exceeded the requirements of SERP. Address Validation and Correction Software must properly categorize addresses as valid or invalid in 98% of the cases, reject 99% of the “non-correctable” addresses and correct 99% of the “correctable” addresses correctly. Software evaluation is limited to specific testing which evaluates the software’s ability to identify or produce accurate address information but not involve any testing or evaluation of any of the additional features or functions that a developer may have incorporated into its software.

The platform information shown on this List of Recognized Software has been supplied by the licensors. The platform information has not been verified by Canada Post. The names of the software packages shown on this List of Recognized Software have been supplied by the licensors. The fact that a software package has been listed in the List of Recognized Software shall not be deemed to be an admission on the part of Canada Post respecting the validity or the registerability, as a trademark, of the name given to that software package by the licensor.
