About the Chile Checking Account
Checking account numbers in Chile differ in length and check digit weights based on the specific bank (Banco de Chile, Santander, Bci, etc.).
This tool generates and validates mock bank accounts utilizing individual Modulo 11 check digit weight matrices mapped to each Chilean financial institute.
Anatomy & Structure of Chilean Checking Accounts (CMF)
Account numbering length and layout depends on the regulated banking institution:
| Position | Field | Length | Meaning & Rule | Example |
|---|---|---|---|---|
| Banco de Chile (12 digits) | Branch + Account + DV | 12 digits | 3 branch digits, 8 account digits and 1 check digit with weights [6, 5, 4, 3, 2, 7, 6, 5, 4, 3, 2] | 123-45678-901 2 |
| Santander Chile (11 digits) | Branch + Account + DV | 11 digits | 2 branch digits, 8 account digits and 1 check digit with weights [5, 4, 3, 2, 7, 6, 5, 4, 3, 2] | 12-34567-890 1 |
Checking Account Validation Algorithm (CMF Modulo 11)
Validation performs weighted Modulo 11 based on bank-specific coefficient vectors:
DV = 11 - (Σ (d[i] × weights[i])) % 11; if DV >= 10, DV = 0
- 1. Identify account length: 12 digits (Banco de Chile) or 11 digits (Santander Chile).
- 2. Multiply base digits by bank specific positional weights.
- 3. Compute remainder of sum modulo 11.
- 4. DV = 11 - remainder; if DV >= 10, DV is set to 0.
- 5. Account is valid when trailing digit matches DV.
