We are using Sitecore 8.2 update 7. I have a scenario. I get postalcode as "N/A" in analytics.GeoIps collection. I'm using Maxmind as the custom lookup provider. In the maxmindd pipeline, I also have a condition, if postalcode from Maxmind is "N/A" fallback to custom zipcode. But still I see PostalCode "N/A" in mongo. Is there a better approach to handle this?
