# Numbers To use MessageBird to connect with customers by placing and receiving voice calls, or sending and receiving SMS, MMS, or WhatsApp messages, you need to connect a number to your workspace. If you don’t have a number yet, or you want to set up a new number, you can purchase one from MessageBird and have it set up and ready to use in your account in a few minutes (for non-KYC markets). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.bird.com/applications/channels/channels/supported-channels/numbers.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
