Answer 1

Depending on the context, you may need to use begin and end anchors. If it's in a validator, sometimes it's implied to match the entire string. If not, it would still match, even if there were more than 4 digits at the beginning, for instance.

Here it is with anchors: ^\d{4}-\d{1,6}-\d{2}$

Answer 2

/[0-9]{4}-[0-9]{0,6}-[0-9]{1,}/
