The Board of County Commissioners

The board of county commissioners is responsible for establishing a uniform identification system for all fixed assets of a county
19 O.S. § 178.1

This simple code number uses a letter to designate the office responsible for an item and a number to indicate a specific item. Many counties have adopted a systematic method of identifying each capital asset using a code number.

The following letters designate the various county offices and departments.

Code Number Examples

Shown below are examples of code numbers for specific items for specific offices. For example, a code number of D-201 would indicate that a typewriter belongs to the office of the county commissioner.

Note:
Some numbers in each code number range will not be used. For example, in the office furniture range, the numbers 111 to 199 are unused in the example. Unused numbers may be assigned to some new equipment type not previously listed, provided a list is maintained that shows what type of equipment is indicated by this new number.

Finally, an addition to the code number could be used to identify separate items of the same type. For example, three chairs could be identified as D-102.1, D-102.2, and D-102.3.

The last number after the decimal point refers to a specific item, and the same decimal number should not be used more than once.

Thus, after a long time, common items (like chairs) might be identified by a rather large number, for example, D-102.27. This number would indicate that the particular chair is the 27th one belonging to the county commissioner's office.

Note:
In the county inventory system, the same identifying inventory number must never be used twice, even if an item no longer exists on the inventory. Once an item is disposed of, the number for that item is never used again.
