De client verifiëren

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. Meer informatie over het beheren van de verbindingsreeks van uw resource.

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);

Look up phone number formatting

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.

Waarschuwing

Provide phone numbers in E.164 international standard format, for example, +14255550123.

Look up operator information for a number

To search for a phone number's operator information, call searchOperatorInformation from the PhoneNumbersClient, passing true for the includeAdditionalOperatorDetails option.

let searchResults = await phoneNumbersClient.searchOperatorInformation([ "<target-phone-number>" ], { "includeAdditionalOperatorDetails": true });

Waarschuwing

Using this function incurs a charge to your account.

Use operator information

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 can also use the operator information to determine whether to send an SMS. For more information, see Send an SMS message.

    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();

Look up phone number formatting

To look up the national and international formatting for a number, call searchOperatorInformation from the PhoneNumbersClient.

ArrayList<String> phoneNumbers = new ArrayList<String>();
phoneNumbers.add("<target-phone-number>");

// Use the free number lookup functionality to get number formatting information
OperatorInformationResult formattingResult = phoneNumberClient.searchOperatorInformation(phoneNumbers);
OperatorInformation formattingInfo = formattingResult.getValues().get(0);

Replace <target-phone-number> with the phone number you're looking up, usually a number you'd like to send a message to.

Waarschuwing

Provide phone numbers in E.164 international standard format, for example, +14255550123.

Look up operator information for a number

To search for a phone number's operator information, call searchOperatorInformationWithResponse from the PhoneNumbersClient, passing true for the IncludeAdditionalOperatorDetails option.

OperatorInformationOptions options = new OperatorInformationOptions();
options.setIncludeAdditionalOperatorDetails(true);
Response<OperatorInformationResult> result = phoneNumberClient.searchOperatorInformationWithResponse(phoneNumbers, options, Context.NONE);

Next, we can print details about the phone number and operator.

String numberType = operatorInfo.getNumberType() == null ? "unknown" : operatorInfo.getNumberType().toString();
String operatorName = "an unknown operator";
if (operatorInfo.getOperatorDetails()!= null && operatorInfo.getOperatorDetails().getName() != null)
{
    operatorName = operatorInfo.getOperatorDetails().getName();
}
System.out.println(operatorInfo.getPhoneNumber() + " is a " + numberType + " number, operated in "
    + operatorInfo.getIsoCountryCode() + " by " + operatorName);

You can also use the operator information to determine whether to send an SMS. For more information, see Send an SMS message.

Alternatively, the client can be authenticated using Microsoft Entra authentication. Using the DefaultAzureCredential object is the easiest way to get started with Microsoft Entra ID and you can install it using the pip install command.

pip install azure-identity

Creating a DefaultAzureCredential object requires you to have AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, 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)

Probleemoplossingsproces

Common questions and issues:

  • Changes to environment variables might 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 might not be available for some phone numbers or could reflect the original operator of the phone number, not the current operator.
