WhatsApp Message Not Delivered? 7 Common Causes and Fixes
Quick answer: Most delivery failures come from the customer's number, a template or quality problem, or a billing issue. Check the failure code in your message status first.
Common causes
- The number is not on WhatsApp or has a wrong country code.
- The customer has not accepted WhatsApp's latest terms.
- Template not approved or paused for low quality.
- Messaging limit reached for the day.
- Marketing frequency limit: Meta may not deliver too many marketing messages to the same user.
- Payment method problem on the messaging account.
- The customer blocked your number.
5-minute checklist
- Format the phone number with country code, for example 91 followed by 10 digits.
- Send the same message to your own number to test.
- Check template status and quality rating.
- Check your messaging limit and billing in Meta.
- Read the error code in your delivery report.
Prevent failures
Clean your contact list, use opted-in customers only and test each template on a small group before a big campaign.
