What's New?

We've completed the worldwide rollout of TomTom Orbis Maps Addresses — capping a nine-month effort that began in June 2025. This is the largest upgrade to Bing Maps address data in years!

Starting with key European markets, we gradually rolled out Orbis data worldwide. Today, the majority of the addresses on Bing Maps come from Orbis. At a scale of over a billion user queries in the past year, that means better API results in Azure Maps  and improved location experiences on Bing Maps , in Bing Search , and in Copilot .

Why Orbis?

This update builds on our longstanding partnership with TomTom, whose address data powered Bing Maps for years. TomTom Orbis Maps represents the next generation of their mapping platform — a single, continuously updated dataset designed for modern mapping. By transitioning to Orbis Addresses, we gain access to:

• 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.

How We Got Here: A Phased Rollout

Rather than a single global cutover, we took a deliberate, phased approach — starting with key European markets where the density and completeness of the new data delivered immediate, measurable improvements. From there, we expanded region by region until the rollout was worldwide.

This strategy was essential for an operation at Bing Maps' scale. Each phase followed the same playbook:

• Ingest and index the new address data for the target region.
• Compare coverage using address point counts and query resolution rates versus the existing corpus.
• Evaluate quality of positional accuracy and regression detection versus the existing baseline.
• Promote to production only when the new data met or exceeded the existing quality bar.

A Real-World Example

Here's what that looks like in practice. Microsoft Development Center Serbia is at Bulevar Mihajla Pupina 6a, Belgrade. Previously, searching for this address on Bing Maps returned a partial match to Bulevar Mihajla Pupina 6 — close, but not the right building. With Orbis address data, the same query now resolves to the exact address at 6a.

What's Next?

The rollout is done, but the work isn't. We will continue working with TomTom to onboard additional Orbis data layers and to refine address quality as new Orbis releases become available. The goal hasn't changed: deliver the best mapping experience we can, everywhere.
