Hello, everyone! I've received my CCNA certificate by mail. There is written on the paper that certificate has a 16 digit validation number located on the bottom left. With that number the CCNA certificate can be validated on the web.
But on my CCNA paper there is no such number. On the bottom left it's written "Certificate validation No" and an empty field follows. There is no 16 digit validation number. Why is it an empty field?
