In the past, Canada Post provided a three-tier rating system (A, B, C) for products on their SERP list. For the past several years, they have discontinued this practice and now simply list products as being SERP recognized without making quality distinctions amongst them.

Canada Post still does note whether the products listed are capable of “Address Correction” or merely “Address Validation”. nCode is capable of both, as well as maintaining backward compatibility with a third category, “Postal Code Lookup”, for which Canada Post no longer tests.

We are forbidden by Canada Post from publishing our SERP test scores, but you should enquire about these scores from any vendor of SERP-recognized software whose products and services you are considering. Not all SERP-recognized software is created equally.
