They should. Every published set of problems that I've ever solved by
hand has. I went searching online for some, and found this page:

http://puzzlepicnic.com/genre?alphametic

which clearly states that exact restriction. The implication is that
you're solving a puzzle in arithmetic (usually addition or long
multiplication), and it is *exactly* as you would have written it with
digits, save that the digits have been replaced with letters (and
carries have been omitted, since that'd make it too easy). You
wouldn't write a leading zero on a number in standard grade-school
arithmetic, so you also won't use a leading zero in anything here.
