Why your sender name takes 24h–7d to show up — and what to do while you wait.
The Display Name is what recipients see at the top of their WhatsApp chat with you — e.g., "Sundara Yoga Studio" instead of just +91 88024 55042. Meta reviews every new Display Name before letting you use it, and the queue is 24 hours to 7 days.
During the wait, your WABA is fully functional — you can send and receive messages — but recipients see your phone number instead of your brand name.
Meta's reviewers look for three things:
You'll get an email from Meta with the rejection reason. The fix:
business.facebook.com → WhatsApp Manager → Phone numbers.Common reasons for rejection: too generic, contains a trademark, contains a URL or phone number, contains promotional language ("Best Prices Now!"), or has trailing/leading whitespace or odd capitalisation.
You can change it up to twice every 30 days. Each change goes through the same review queue. If you change it more than that within 30 days, Meta locks the field — wait it out.
