# Error codes
When you make a request to the Signicat's Data Verification API and there is an error, you will receive a response with an error message that contains an error code.
If you encounter an error and need help with your issue, you can always get in touch with Support at support@signicat.com.
Alternatively, you can check out our community forum (opens new window) for answers to commonly asked questions.
