If you are referring to the Location code that is in Adagio Inventory, the maximum number of characters the code can be is 3. This cannot be expanded due to the data structure. The location Description can be much longer (30 characters, I believe).
If you were hoping to create a 10-character code, you won't be able to do this - you'll have to be creative in order to fit this into 3 characters. Maybe something alpha-numeric like AB1 or something without all the vowels like LCT for 'location'.
