Renumbering fixed assets - Ideas on where to start from the profit centres and analysis codes?

My company has decided to renumber their assets which include items from Tanks to Office equipment.
Can anyone suggest Ideas on where to start from the profit centres and analysis codes below
PROFIT CENTRE ANALYSIS CODE
Commercial Fuel Tanks
Tanks Sundry plant
Lubricants Office equipment
Operations Office/Utes Cars and utilities
Operations Driver/trucks Land and buildings
Head Office Truck and trailers

however the company only wants to use numeric codes for their assets no alpha codes
