Table of Contents
What Causes This Error
Error #131037 occurs when the display name certificate for your phone number is not currently active on the number being used for sending.
Even when a display name shows as Approved in your account, the certificate still needs to be applied to the phone number before messages can be sent. For Cloud API numbers, this is done through re-registration — a standard step that activates the certificate on the number.
How to Resolve It
Re-register your phone number using the WhatsApp Cloud API. This activates the display name certificate on the number and is a standard step required for the certificate to take effect.
Use the Correct PIN
Retry Sending
Once re-registration completes successfully, retry sending your template message. The error should no longer appear.

Frequently Asked Questions
Q: My display name shows as Approved. Why am I still getting this error?
An approved display name and an active certificate are two separate things. The certificate must be applied to the phone number through re-registration before messages can be sent. Re-registration is a required step even when the display name shows as approved in your account.
Q: Will re-registration affect my existing templates or contacts?
No. Re-registration only activates the display name certificate on the phone number. It does not affect your approved templates, contact data, or any other account settings.
Q: What PIN should I use for re-registration?
If two-step verification is enabled on the number, use your existing 6-digit two-step verification PIN. If two-step verification is not enabled, you may set a new 6-digit PIN during re-registration.
Q: Does this error affect all templates or just specific ones?
Error #131037 is related to the phone number's certificate, not individual templates. It typically affects all outgoing messages from that number. If the error only appears for specific templates after re-registration, contact support with the details listed above.
Q: Where can I find my Phone Number ID?
Your Phone Number ID can be found in Meta WhatsApp Manager under Account tools → Phone numbers. It is also visible in the CRM under Settings → WhatsApp in your sub-account.
