Bing Maps to Azure Maps API migration

Bing Maps to Azure Maps API migration is now a planning priority for teams relying on Bing Maps APIs for geocoding, routing, search, or map rendering. With Bing Maps for Enterprise retiring on 30 June 2028, moving to Azure Maps is the clearest path to continuity without forcing a full cloud transformation

The good news? This doesn’t have to trigger a full cloud transformation. If your goal is to keep your mapping services running smoothly, Azure Maps lets you take a focused, API-level approach. 

 Why Bing Maps to Azure Maps API migration is the natural next step

Azure Maps is Microsoft’s next-generation mapping and geospatial platform. It carries forward the core capabilities developers know from Bing Maps, while strengthening areas like authentication, compliance and spatial analytics. 

If you’re already calling Bing Maps REST APIs, this is a structured migration rather than a rebuild. Azure Maps covers the same functional ground: 

• Geocoding and reverse geocoding, including structured and fuzzy search 
• Routing for directions, distance matrix, truck routing and isochrones 
• Map rendering with road, satellite, traffic and weather tiles 
• Search, including autocomplete and points of interest 
• Traffic incidents and real-time flow data 
• Time zone and weather services 

Teams using Bing Maps Spatial Data Services will also find clear Azure Maps equivalents, including batch geocoding and spatial queries. 

These enhancements often open up opportunities beyond simple migration, particularly where location data plays a bigger role in product, operational, or commercial decisions. 

You don’t need a full Azure cloud investment 

This is where many migrations get held up unnecessarily. 

Azure Maps runs as a standalone service. You only need an Azure subscription and a provisioned Maps resource, not a full cloud transformation. 

In practical terms, you’re updating endpoints, switching authentication, and continuing to build. For teams focused on continuity, this keeps your mapping infrastructure current without expanding your Azure footprint. 

Most teams provision Azure Maps themselves in minutes. 

For organisations already invested in Microsoft, this is more than a migration checkpoint. It’s an opportunity to move with greater control and intent. 

Our Accelerate Partner Program helps you unlock that next stage, bringing together technical expertise, cost optimisation, security, and commercial guidance to turn your Azure investment into scalable, predictable growth. 

What changes at the API level 

The changes are well defined and, for most teams, straightforward to work through. 

Authentication 

Bing Maps relied on a single API key. Azure Maps supports shared key authentication, Microsoft Entra ID and shared access signature tokens. For API-only migrations, shared key authentication is the closest equivalent and quickest to implement. 

Endpoints and parameters 

Endpoints change, and request and response formats differ in naming and structure. Every API call needs updating, but the underlying logic remains the same. 

Web SDK 

If you’re using the Bing Maps JavaScript control, the Azure Maps Web SDK replaces it. Initialisation changes, atlas.min.js replaces the Bing Maps script, and maps render using 512 by 512 pixel tiles. 

What you gain with Azure Maps 

This isn’t just a like-for-like replacement. Azure Maps adds capabilities Bing Maps didn’t offer: 

• Weather APIs and weather map tiles 

• IP-based geolocation 

• Built-in compliance support for GDPR, ISO, FedRAMP and HIPAA 

• Active feature development, including newer routing enhancements 
• Extensive code samples to accelerate implementation 

A practical Bing Maps to Azure Maps API migration approach

You don’t need a transformation programme. You need a clear plan. 

1. Assess your current Bing Maps usage

Start with a focused Location Intelligence Assessment, reviewing your existing APIs, SDKs and data services. 

Each call is mapped to its Azure Maps equivalent, behavioural differences are flagged, and opportunities to optimise are identified. 

This is often where teams uncover unnecessary complexity or hidden cost before making any changes. 

2. Provision Azure Map

Create an Azure Maps resource in the Azure portal and retrieve your subscription key. This is a lightweight step, typically completed in minutes. 

3. Guide the API migration

For most teams, the migration itself is manageable. 

Where complexity tends to appear is in edge cases, performance differences, and handling API behaviour at scale. 

If needed, taking a more structured approach here can help reduce friction and avoid unnecessary rework as you move through the transition. 

4. Test and validate

This is where confidence is built. 

Focus on validating three things: 

• Accuracy: Ensure results meet expectations across core use cases 

• Performance: Test behaviour under typical and peak usage 

• Cost: Monitor early usage and set budget controls 

Catching small differences here prevents bigger issues later, particularly as usage begins to scale. 

5. Go live with confidence

Roll out progressively. Monitor usage, set budget controls, and track performance to avoid surprises. 

If you’re scaling usage or expanding further into Azure, ongoing monitoring and cost management become just as important, particularly for teams balancing growth with limited internal resources, this would be excellent timing to seek additional support with our Azure Monitoring Service. 

Why 2026 is the year to move 

The 30 June 2028 deadline may feel distant, but licensing realities are already tightening. 

Organisations renewing Bing Maps licences from August 2026 onwards can no longer secure consecutive 12-month terms that reach the end date. For some teams, migration timelines are already compressing. 

Starting now gives you space to migrate methodically, test properly, and avoid unnecessary pressure closer to the deadline. 

Talk to our Mapping Specialists 

Whether you’re planning a straightforward API switch or want a second opinion on complexity, we’ll help you map out the most efficient route forward. 

Start with a Location Intelligence Assessment, a clear view of your current setup, your migration path, and where you can optimise along the way. 

If you’re ready to go further, we can support how your migration fits into a broader Azure strategy, helping you scale with more control, confidence, and the right level of support as demand grows.
