It says serial number invalid

Welcome to the HP Community Forum.

What is "it" that says the serial number is invalid?

That means, where do you see the message?

What is the product / model of your printer?

How to find

I have the same issue. I'm trying to add the serial number ot my account dashboard but it doesn't accept it.

I can't even raise a support request because the virtual agent asks for the serial number as well and it also says that it's invalid!
