Final answer:
An organization's list of all its accounts and the related account numbers is called a chart of accounts.
Step-by-step explanation:
An organization's list of all its accounts and the related account numbers is known as a chart of accounts. This list is used to organize the company's finances and is integral to its accounting system. It is different from a ledger, which is a record of transactions divided among individual accounts but does not usually include the account numbers. A journal is a chronological record of all transactions before they are transferred to the ledger. Meanwhile, a trial balance is a worksheet where the balances of all ledgers are compiled into debit and credit account column totals that should match.
