Account code: This is usually a three-digit code that describes the specific type of account. For example, it may help differentiate the accounts for fixed assets from the accounts for supplies or transportation expenses.

A chart of accounts (COA) is an index of all of the financial accounts in a company's general ledger. In short, it is an organizational tool that lists by category and line item all of the financial transactions that a company conducted during a specific accounting period.

The commonly accepted order is as follows: 1000 – 1900 is assets, 2000 – 2900 is liabilities, 3000 – 3900 is equity, 4000 – 4900 is revenue and 5000 – 5900 is expenses. These are listed in numerical order to make it easier to find any specific account.
