+# Try Number Lookup
+
+Try Number Lookup is a tool in Azure portal to help customers confirm that they phone number they want to communicate with is valid as well as retrieve details to identify if its country, carrier and type. This feature enables developers to quickly test Azure Communication Services number lookup capabilities, without an existing app or code on their end.
+
+## Prerequisites
+
+- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/free/).
+- A deployed Communication Services resource. Create an [Azure Communication Resource](../../quickstarts/create-communication-resource.md).
+
+## Overview
+
+Open the [Azure portal](https://portal.azure.com/#home) and search for **Number Lookup**. Then Enter a phone number that you want to lookup or validate. You can either check national and international format for free or request details about number type, country and carrier for a fee. The tool will also generate the associated code. You can also select **Use my connection string** to automatically populate the `connection string` for the resource.
