because those UIDs are usually used by services/system accounts.

Do a "more /etc/passwd" and you'll see the system users and note that most of their UIDs will be quite low.

there are no uids assigned for 400 - 499, is there a problem with using these?

by convention, you shouldn't. in practice, it _probably_ won't break anything.

If you don't have any servers on the system using IDs in that range, your system may try to create one and have a conflict, but I would think that'd be kind of unusual.
