My client wants this font for their last minute invitation but I don't even know what to search online to try finding something with the "slashed zero" look

Can someone help?

Thank you so very much!

You would search for “typewriter” and check which of those fonts have a slashed zero.

For commercial fonts, the slashed zero might be an OpenType feature, as in FF Trixie for example:

Thank you Ralf! I will try that! When I clicked on the link you sent - everything is in German :)

Just remove the "/de" part: https://www.dafont.com/theme.php?cat=113&text=123450&fpp=100

I know! :) That's what I did. I was just replying to Ralf suggestion
