How to Offset Page Numbering by +1

Hello,
I’ve noticed a mismatch between the page numbers displayed on each page of my export and the numbering shown in Adobe Reader.
There’s always a 1-page offset, because the cover page isn’t counted in the footer numbering.

As a result, when I ask a client to sign, for example, page 18, they don’t know whether I mean the page number shown in Adobe Reader or the one printed in the footer.

I’d like each displayed page number to match its actual position within the PDF.
How can I increase the footer page number by +1?

Note: I don’t want any page number to appear on the cover page or title pages — I simply want the numbering itself to be offset by +1.

Thanks in advance!
