Can I Use My Existing WhatsApp Number for the WhatsApp Business API?
Quick answer: A number already active on the WhatsApp or WhatsApp Business app usually needs extra steps before it can be used with the API. For most businesses, a fresh number is the simplest and safest choice.
Number requirements
- You must be able to receive an SMS or voice call on it. Landline numbers can verify by voice call.
- It should belong to your business and be one you will keep long term.
- It must not already be registered to another WhatsApp Business API provider.
If the number is on the WhatsApp app
Usually you need to delete that WhatsApp account first, and your old chat history will not move to the API. Meta also has options for some Business app numbers to work with the API at the same time. Eligibility depends on Meta, so ask us before you make any change.
Our recommendation
- Use a new SIM or virtual-friendly number for the API, and keep your personal WhatsApp separate.
- Put the number on your website, packaging and ads so customers know where to reach you.
