Why is my display name rejected by WhatsApp?
All display names should have a clear relationship with your business and should not violate the WhatsApp Commerce and Business policies. WhatsApp does not provide the exact reason for display rejections, but you can resubmit a new display name or appeal for the rejected one.

If the display name is rejected few times by WhatsApp, you could submit a
ticket to our Stella Support team and we could submit an appeal to WhatsApp.
