async function main() {
// quickstart code will go here
}
main();
Use the npm install
command to install the Azure Communication Services Phone Numbers client library for JavaScript.
npm install @azure/communication-phone-numbers@1.3.0-beta.4 --save
The --save
option adds the library as a dependency in your package.json file.
Import the PhoneNumbersClient from the client library and instantiate it with your connection string, which can be acquired from an Azure Communication Services resource in the Azure portal. Using a COMMUNICATION_SERVICES_CONNECTION_STRING
environment variable is recommended to avoid putting your connection string in plain text within your code. Learn how to manage your resource's connection string.
Add the following code to the top of number-lookup-quickstart.js:
const { PhoneNumbersClient } = require('@azure/communication-phone-numbers');
// This code retrieves your connection string from an environment variable
const connectionString = process.env['COMMUNICATION_SERVICES_CONNECTION_STRING'];
// Instantiate the phone numbers client
const phoneNumbersClient = new PhoneNumbersClient(connectionString);
To search for a phone number's operator information, call searchOperatorInformation
from the PhoneNumbersClient
.
let formattingResults = await phoneNumbersClient.searchOperatorInformation([ "<target-phone-number>" ]);
Replace <target-phone-number>
with the phone number you're looking up, usually a number you'd like to send a message to.

Using this functionality will incur a charge to your account.
You can now use the operator information. For this quickstart guide, we can print some of the details to the console.
First, we can print details about the number format.
let formatInfo = formattingResults.values[0];
console.log(formatInfo.phoneNumber + " is formatted " + formatInfo.internationalFormat + " internationally, and " + formatInfo.nationalFormat + " nationally");
Next, we can print details about the phone number and operator.
let operatorInfo = searchResults.values[0];
console.log(operatorInfo.phoneNumber + " is a " + (operatorInfo.numberType ? operatorInfo.numberType : "unknown") + " number, operated in "
+ operatorInfo.isoCountryCode + " by " + (operatorInfo.operatorDetails.name ? operatorInfo.operatorDetails.name : "an unknown operator"));
You may also use the operator information to determine whether to send an SMS. For more information on sending an SMS, see the SMS Quickstart.

Phone Number clients can be authenticated using connection string acquired from an Azure Communication Services resource in the Azure portal. Using a COMMUNICATION_SERVICES_CONNECTION_STRING
environment variable is recommended to avoid putting your connection string in plain text within your code. Learn how to manage your resource's connection string.
// This code retrieves your connection string from an environment variable.
string? connectionString = Environment.GetEnvironmentVariable("COMMUNICATION_SERVICES_CONNECTION_STRING");
PhoneNumbersClient client = new PhoneNumbersClient(connectionString, new PhoneNumbersClientOptions(PhoneNumbersClientOptions.ServiceVersion.V2024_03_01_Preview));
Phone Number clients can also authenticate with Microsoft Entra authentication. With this option,
AZURE_CLIENT_SECRET
, AZURE_CLIENT_ID
, and AZURE_TENANT_ID
environment variables need to be set up for authentication.
// Get an endpoint to our Azure Communication Services resource.
Uri endpoint = new Uri("<endpoint_url>");
TokenCredential tokenCredential = new DefaultAzureCredential();
client = new PhoneNumbersClient(endpoint, tokenCredential);
To look up the national and international formatting for a number, call SearchOperatorInformationAsync
from the PhoneNumbersClient
.
OperatorInformationResult formattingResult = await client.SearchOperatorInformationAsync(new[] { "<target-phone-number>" });

The client can be authenticated using a connection string acquired from an Azure Communication Services resource in the Azure portal. Using a COMMUNICATION_SERVICES_CONNECTION_STRING
environment variable is recommended to avoid putting your connection string in plain text within your code. Learn how to manage your resource's connection string.
// This code retrieves your connection string from an environment variable
String connectionString = System.getenv("COMMUNICATION_SERVICES_CONNECTION_STRING");
PhoneNumbersClient phoneNumberClient = new PhoneNumbersClientBuilder()
.connectionString(connectionString)
.buildClient();
Alternatively, you can authenticate using Microsoft Entra authentication. Using the DefaultAzureCredentialBuilder
is the easiest way to get started with Microsoft Entra ID. You can acquire your resource name from an Azure Communication Services resource in the Azure portal.
// You can find your resource name from your resource in the Azure portal
String endpoint = "https://<RESOURCE_NAME>.communication.azure.com";
PhoneNumbersClient phoneNumberClient = new PhoneNumbersClientBuilder()

, and AZURE_TENANT_ID
already set as environment variables with their corresponding values from your registered Microsoft Entra application.
For a ramp-up on how to get these environment variables, you can learn how to set up service principals from CLI.
Once the azure-identity
library is installed, you can continue authenticating the client.
from azure.identity import DefaultAzureCredential
# You can find your endpoint from your resource in the Azure portal
endpoint = 'https://<RESOURCE_NAME>.communication.azure.com'
try:
credential = DefaultAzureCredential()
phone_numbers_client = PhoneNumbersClient(endpoint, credential)

Common questions and issues:
- Changes to environment variables may not take effect in programs that are already running. If you notice your environment variables aren't working as expected, try closing and reopening any programs you're using to run and edit code.
- The data returned by this endpoint is subject to various international laws and regulations, therefore the accuracy of the results depends on several factors. These factors include whether the number was ported, the country code, and the approval status of the caller. Based on these factors, operator information may not be available for some phone numbers or may reflect the original operator of the phone number, not the current operator.
In this quickstart you learned how to:
- Look up number formatting
- Look up operator information for a phone number
