Then the first part is interpreted (in the US, anyway) as a middle name, not as part of the last name. I did run into a recently married woman who did that: dropped her middle name, moved her last to the middle, and used her spouse's last name.

More commonly, places that don't take hyphens tend to just run the two names together: Axel-Smith becomes AxelSmith.

Programmers can be really dumb.

My mom didn't hyphenate, but she does include her maiden name when writing her full name, after her middle name. It never even occurred to me that that's uncommon.

As someone who's mexican I encounter that more than one would think since I have 2 last names and it gets weird sometimes since I also have a middle name.
