Microsoft today announced that it has completed the rollout of its largest upgrade to Bing Maps address data in years. The company started the rollout of TomTom Orbis Maps addresses in Bing Maps back in June 2025. After nine months, the rollout is finally complete worldwide.
TomTom Orbis Maps is built on a common mapping standard created by Overture Maps Foundation partners. It uses data from the Overture Maps Foundation, OpenStreetMap (OSM), partner data, sensor-derived observations (SDOs), and TomTom"s own data. Microsoft claims that TomTom Orbis Maps will offer a continuously updated dataset, which will allow Bing Maps to enjoy the following:
- Greater address coverage — many more address points worldwide.
- Improved positional accuracy — address points that land closer to their true geographic locations.
- Fresher data — Orbis Maps is built on a continuous update model, so address data stays current as the real world changes.
Instead of replacing the entire Bing Maps dataset with TomTom Orbis in a single attempt, Bing team took a phased approach. It ingested and indexed new address data for the target region, compared its coverage and query resolution rates against the existing dataset, and evaluated positional accuracy while checking for regressions against the baseline. The rollout to production was completed only after the new data met or exceeded the established quality standards.
Microsoft started with key European markets where the density and completeness of the new data resulted in significant improvements. Later, it expanded the rollout to other regions. While the initial data layer rollout is complete, the company is still working with TomTom to onboard additional Orbis data layers and to refine address quality.
Consumers can now experience the improved address quality in Microsoft"s location experiences on Bing Maps, in Bing Search, and in Copilot. In addition, Azure Maps will now deliver better map API results thanks to Orbis data.
