Note: This list is very much a work-in-progress. Let me know if you can confirm this info or if you think any of it is incorrect.
I have noticed a lot of confusion about how to add listings to Apple Maps for different countries. While you can do so via the “Report a Problem” screen on Apple Maps, all businesses should also make sure their data is up to date on the relevant data supplier for their country. Failing to do this could mean that your business info gets overwritten when Apple gets a new update from a supplier whose data it trusts more than the data you have submitted.
I have put together this list of data vendors by country to help make it easier to figure out where to go to update your data:
|Business Listings Supplier||Country|
|Axciom||Canada & United States|
|Factual||Appears to be big part of Apple Maps UK See here.|
|Open Street Map||Global|
|Yelp||All Yelp Countries|
This list is based on information found in the Apple Maps Acknowledgments page. I’ll keep this list updated as I get new information. Feel free to ping me if you have any.
