Azure Maps Geolocation client library for .NET

Azure Maps Geolocation is a library that can find geolocation to a location or points of interest.

Getting started

Install the package

Install the client library for .NET with NuGet:

dotnet add package Azure.Maps.Geolocation --prerelease


You must have an Azure subscription and Azure Maps account.

To create a new Azure Maps account, you can use the Azure Portal, Azure PowerShell, or the Azure CLI. Here's an example using the Azure CLI:

az maps account create --kind "Gen2" --account-name "myMapAccountName" --resource-group "<resource group>" --sku "G2"

Authenticate the client

There are 2 ways to authenticate the client: Shared key authentication and Azure AD.

Shared Key authentication
  • Go to Azure Maps account > Authentication tab
  • Copy Primary Key or Secondary Key under Shared Key Authentication section
// Create a MapsGeolocationClient that will authenticate through Subscription Key (Shared key)
AzureKeyCredential credential = new AzureKeyCredential("<My Subscription Key>");
MapsGeolocationClient client = new MapsGeolocationClient(credential);
Azure AD authentication

In order to interact with the Azure Maps service, you'll need to create an instance of the MapsGeolocationClient class. The Azure Identity library makes it easy to add Azure Active Directory support for authenticating Azure SDK clients with their corresponding Azure services.

To use AAD authentication, set the environment variables as described in the Azure Identity README and create a DefaultAzureCredential instance to use with the MapsRouteClient.

We also need Azure Maps Client ID which can get from Azure Maps page > Authentication tab > "Client ID" in Azure Active Directory Authentication section.

// Create a MapsGeolocationClient that will authenticate through Active Directory
TokenCredential credential = new DefaultAzureCredential();
string clientId = "<Your Map ClientId>";
MapsGeolocationClient client = new MapsGeolocationClient(credential, clientId);
Shared Access Signature (SAS) Authentication

Shared access signature (SAS) tokens are authentication tokens created using the JSON Web token (JWT) format and are cryptographically signed to prove authentication for an application to the Azure Maps REST API.

Before integrating SAS token authentication, we need to install Azure.ResourceManager and Azure.ResourceManager.Maps (version 1.1.0-beta.2 or higher):

dotnet add package Azure.ResourceManager
dotnet add package Azure.ResourceManager.Maps --prerelease

In the code, we need to import the following lines for both Azure Maps ResourceManager:

using Azure.Maps.Geolocation;
using Azure.Core;
using Azure.ResourceManager;
using Azure.ResourceManager.Maps;
using Azure.ResourceManager.Maps.Models;

And then we can get SAS token via List Sas API and assign it to MapsGeolocationClient. In the follow code sample, we fetch a specific maps account resource, and create a SAS token for 1 day expiry time when the code is executed.

// Get your azure access token, for more details of how Azure SDK get your access token, please refer to
TokenCredential cred = new DefaultAzureCredential();
// Authenticate your client
ArmClient armClient = new ArmClient(cred);

string subscriptionId = "MyMapsSubscriptionId";
string resourceGroupName = "MyMapsResourceGroupName";
string accountName = "MyMapsAccountName";

// Get maps account resource
ResourceIdentifier mapsAccountResourceId = MapsAccountResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, accountName);
MapsAccountResource mapsAccount = armClient.GetMapsAccountResource(mapsAccountResourceId);

// Assign SAS token information
// Every time you want to SAS token, update the principal ID, max rate, start and expiry time
string principalId = "MyManagedIdentityObjectId";
int maxRatePerSecond = 500;

// Set start and expiry time for the SAS token in round-trip date/time format
DateTime now = DateTime.Now;
string start = now.ToString("O");
string expiry = now.AddDays(1).ToString("O");

MapsAccountSasContent sasContent = new MapsAccountSasContent(MapsSigningKey.PrimaryKey, principalId, maxRatePerSecond, start, expiry);
Response<MapsAccountSasToken> sas = mapsAccount.GetSas(sasContent);

// Create a SearchClient that will authenticate via SAS token
AzureSasCredential sasCredential = new AzureSasCredential(sas.Value.AccountSasToken);
MapsGeolocationClient client = new MapsGeolocationClient(sasCredential);

Key concepts

MapsGeolocationClient is designed for:

  • Communicate with Azure Maps Geolocation SDK endpoint to get location from given IP address

Learn more about examples in samples

Thread safety

We guarantee that all client instance methods are thread-safe and independent of each other (guideline). This ensures that the recommendation of reusing client instances is always safe, even across threads.

Additional concepts

Client options | Accessing the response | Long-running operations | Handling failures | Diagnostics | Mocking | Client lifetime


You can familiarize yourself with different APIs using our Samples.

Before calling geolocation APIs, instantiate a MapsGeolocationClient first. Below example uses AAD to create the client instance:

// Create a MapsGeolocationClient that will authenticate through Active Directory
TokenCredential credential = new DefaultAzureCredential();
string clientId = "<Your Map ClientId>";
MapsGeolocationClient client = new MapsGeolocationClient(credential, clientId);

Get Location

This service will return the ISO country code for the provided IP address. Developers can use this information to block or alter certain content based on geographical locations where the application is being viewed from.

//Get location by given IP address
IPAddress ipAddress = IPAddress.Parse("2001:4898:80e8:b::189");
Response<CountryRegionResult> result = client.GetCountryCode(ipAddress);

//Get location result country code
Console.WriteLine($"Country code results by given IP Address: {result.Value.IsoCode}");

For more detailed examples, please see geolocation samples page.



When you interact with the Azure Maps services, errors returned by the Language service correspond to the same HTTP status codes returned for REST API requests.

For example, if you pass wrong IP address, an error is returned, indicating "Bad Request" (HTTP Status code: 400).

    // An invalid IP address
    IPAddress inValidIpAddress = IPAddress.Parse("2001:4898:80e8:b:123123213123");

    Response<CountryRegionResult> result = client.GetCountryCode(inValidIpAddress);
    // Do something with result ...
catch (FormatException e)
