YourBusinessNumber set out to do in 2021. It’s developed it own unique - it claims - internal tools to make sure that UID is verified by WhatsApp Business and that the connection is made between a small business owner's personal number and its new WAB number (the cost is a low £4.99 per month). In this way, the small business person can still run their business from their own phone, without having to give out their personal number.
