It depends on what version of the Unicode standard you are talking about. From Wikipedia:

Older versions of the standard used similar notations, but with slightly different rules. For example, Unicode 3.0 used "U-" followed by eight digits, and allowed "U+" to be used only with exactly four digits to indicate a code unit, not a code point.

That was the helpful reference. But the reason for that change is not mentioned. Was it just a whim of the committee?
