Meta Tech ProviderWhatsApp error 131026: The number can't receive the message
The recipient — not your account. What it means, how to fix it, and whether to retry.
WhatsApp error 131026 means the message could not be delivered to that number — usually because it is not a WhatsApp number, or the person has not accepted WhatsApp's latest terms of service or is using a very old version of the app. Check the number with the person.
Why it happens
- The number is not registered on WhatsApp.
- The person has not accepted WhatsApp's latest terms of service.
- The person is on an old version of WhatsApp that cannot receive this kind of message.
- The number was typed wrongly, or is missing its country code.
How to fix error 131026
- Confirm the number with the person, including the country code.
- Ask them to update WhatsApp and accept the latest terms.
- If they aren't on WhatsApp, reach them another way.
Should you retry?
Not until something about the number changes — the same send will fail the same way.
How to prevent it
- Store numbers in full international format.
- Watch for numbers that fail repeatedly and clean them out of your lists.
