 <p>7d1bad12 is a Hex string and not your normal string. I assume you gave a delete request and shortly you logged into the system and saw your VPC still existing. VPC deletion is a time consuming process and it takes time before your VPC is deleted. When the API says it returned successfully it means that the SDK was able to send the delete request successfully and this delete request is asynchronous and therefore, it returns immediately. If your VPC was empty then after some time it should go away from the AWS console.</p>
