Our tools give you the option of choosing either postal/zip code or address-based lookups. When you're configuring your campaign's Location-Based Targets, it's worth noting that postal code lookups are not as accurate as address-based lookups. However, they do guarantee a higher conversion rate for your campaigns.
Using postal codes is error-prone because a postal code can match multiple boundaries and because postal codes change constantly.
With postal code lookups, you may sometimes get inaccurate results - this doesn't mean that the data in our system is incorrect. Our developers - in collaboration with Open North - are working hard to make postal code-based lookups more accurate.
