You can send before your name is approved; until then, chats show your number. Meta's naming rules, and how to fix or change the name.
The Display Name is what recipients see at the top of their WhatsApp chat with you, for example "Horizon Holidays" instead of just your phone number. You don't need an approved name to start sending messages. Meta reviews the name once your business qualifies for a higher messaging limit, and it doesn't publish how long that review takes. Meta's rules here are as of October 2026.
Until the name is approved, it shows on your WhatsApp profile, but chats show your phone number at the top.
Three of the things Meta's guidelines check:
Meta marks the name as declined. Zymbler shows the name on the number's row in Channels, but it has no change or appeal button, so the fixes below happen with Meta, not in Zymbler. Review Meta's display name guidelines, then edit the name, or file an appeal through Meta's Developer Support.
The guidelines Meta publishes say a name:
A department can be fine when the business name comes with it: Meta accepts "Fresh Produce Customer Service Department". Only the bare generic term is rejected.
You can change it up to 10 times in 30 days. Meta has to review and approve each change before the new name is used. If your approved name doesn't show on your chats, contact us. If your number is an Official Business Account, contact Meta's direct support instead.
