Customer Service on WhatsApp Without Exposing Customers
Businesses serving customers on WhatsApp can teach them good habits or accidentally train them to fall for scams. What to ask, what never to request, and how to verify customers.
Every time a business asks a customer for a PIN, a card number or a photo of their ID in a chat, it teaches that customer that such requests are normal. Scammers then make the same request, and customers comply. Good customer service on WhatsApp protects customers by setting clear, safe expectations.
Never ask customers for
- Passwords, PINs or one-time codes.
- Full card numbers or card security codes.
- Photos of ID documents in chat, unless legally required and handled securely. See ID documents on WhatsApp.
- Screen sharing or remote access. See screen sharing scams.
Safer ways to verify and serve
- Use order or booking references.
- Call back on the number on the customer's account.
- Send payments through your payment provider's secure links, and describe what they look like.
- Keep only the data you need, and delete chats you no longer need to keep.
Say it in your greeting message: "We will never ask for your PIN, password or codes, and we never change our bank details by message."
