: Recommended Font for distinguishing upper/lowercase letters and numbers We have a small in-house application which generates a string consisting of upper and lowercase letters, and the numbers 0-9.

I would suggest IBM Plex

It comes in 48 styles and the family includes both a sans-serif, a serif, and a monospaced variant, all with excellent distinctiveness (1/I/l and O/0 are easily distinguished and it has both dotted and slashed alternates available for zero), and the entire family is free.

I'd suggest giving Courier Prime Code a whirl as the lowercase o is round while the uppercase O is more of an ellipse, and it has a slashed zero that's even more elliptical. The 1, i, j, I, J, 5 and S characters all have distinctive features as well. Best of all, it's free and Courier Prime (serif) and Courier Prime Sans are complementary typefaces (in case you need some variety).
