How long does it take for Meta to verify a WhatsApp template?

In most cases, Meta's AI Validation processes will take just a few minutes to verify a Message template.

However, in some rare cases where a manual review is required, this may take 1-2 days.

Additionally, templates made using newly created WhatsApp accounts may take up to a day to validate. As you continue to send messages using your WhatsApp account, the validation time will reduce dramatically.
