For those interested, the font is Core Humanist Sans. Thank god for www.identifont.com
Try typing out QWERTY 123 in the sample text box on
MyFonts, you'll see the 'Q' and '3' don't match. Appears to be a different typeface.
If it's close enough for what you need might as well use it though
. I haven't had much success with font ID sites in the past, even with clean samples, as often they can be custom typefaces or the engine doesn't recognize an exact match.
