Structure:
Charts of accounts follow a hierarchical structure with three levels:

Account classes (top level)
Account groups (subdivision)
Individual accounts (posting level)

Numbering:
Each account class is usually assigned a one-digit number. This is the first digit of the full account number. This allows accounts to be quickly assigned to a class - at least as long as you don't try to interpret the system "creatively".

Function:
Account classes help to chart of accounts structured and analysable. They enable a comprehensible accounting logic and form the basis for transparent business analyses.

Examples from common charts of accounts:

Industry Chart of Accounts (ICA): Account classes 0-8 for business accounting (accounting area I), account class 9 for cost accounting and accruals (accounting area II).
SKR03 (DATEV): Account classes 5 and 6 for cost accounting.
Joint chart of accounts (GKR):
- Account class 2: Neutral expenses/income
- Account class 4: Cost types
- Account classes 5/6: Cost centres
- Account class 7: Cost units, inventories
- Account class 8: Cost unit income
- Account class 9: Closing
