# Connecting WhatsApp Number To start using **WhatsApp Catalog Automation** and access all features, your business must connect a number through the **WhatsApp Business API**. {% embed url="" %} ### Number Requirements 1. You need a **mobile or landline number** that has **not been previously used** on WhatsApp. 2. If you already use the number on WhatsApp Personal or WhatsApp Business App, you must **delete the account from the app** (do not uninstall the app). * For better quality, we recommend using a **new number**. 3. Avoid using numbers that were previously **blocked by WhatsApp** or connected to any **automated software**, as this may increase the risk of future blockages. 4. The number must be **active and able to receive a Text or Voice OTP**, since WhatsApp will send one during the verification process. --- # 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.
