How can you tell if an account is not restricted (and thus can be used for purchases not eligible to restricted fund accounts)?

Account conventions used in CCB:

Account:
A58-

Restricted?

Notes

3xxx
4xxx

Unrestricted

Enterprise accounts, etc.

5xxx
6xxx
7xxx

n/a

Not currently used

81
87
88

Unrestricted

Gifts, endowments

82

Restricted

Not generally used

83
84
85
86

Restricted

Federally sponsored funds

University-wide, looking at an account's "Sub group code" indicates if an account is restricted or not. That requires looking it up in Kuali, or the like.
