Will WhatsApp usernames hide my customers' phone numbers from my restaurant?

Sometimes. When a customer has a username, the app shows it instead of their number. You still see the number if you chatted or called in the last 30 days, or they are in your contacts.

• The 30-day check is per business phone number. It counts if you messaged or called them, or they messaged or called you.
• A customer in your contact book keeps their number visible to you.
• Otherwise the API sends a business-scoped user ID (BSUID). It identifies each user per business portfolio.
• If a customer with a username chats with you first, you will not see their number unless they choose to share it.
