WhatsApp error 131026: the message couldn't be delivered
WhatsApp accepted your request but couldn't deliver it to the person. Most of the time the number doesn't have WhatsApp, was typed in the wrong format, or the customer's app is too old.
Common causes
- The number isn't registered on WhatsApp
- The country code is missing or doubled
- A local leading zero wasn't removed
- The customer hasn't accepted WhatsApp's latest terms
- The customer's WhatsApp app is very outdated
- The number is a landline
What to do
- 01
Check the format
Numbers should be in international format, for example 201012345678 for an Egyptian mobile, with no plus sign issues or extra zeros.
- 02
Use a fallback
In Vrobo, failed WhatsApp confirmations can move to an automated call or SMS so the order still gets confirmed.
- 03
Fix it at checkout
Ask for a mobile number with the country code preselected to cut bad numbers at the source.
Questions, answered.
Am I charged for 131026 messages?
No. Undelivered messages aren't billed by Meta.
Does it affect my number's quality?
Not directly, but sending many messages to invalid numbers is a sign to clean your data.
