How to display the VAT Number label on the invoice?

Hi, some clients have VAT numbers which I’ve input. Is it possible to display the VAT label on the invoice that’s output? I’ve checked the PDF download and it also doesn’t show the label.
I’m using the latest self-hosted version.
Thanks in advance?
