ANSWER-1) The account names can be non-unique but identification numbers are unique. The account numbers are unique with each digit representing a division of the organization, the type of account, the department, etc. The account number identifies the individual account; and if a person hold two accounts at the same place, although the account names will be the same, but the account numbers will be different thus there are lesser chances of error. Moreover it ease the task of locating specific accounts.
