What are Alias Accounts?
An Alias Account connects a Holder (individual or company) to a specific Midaz ledger account. In Midaz Module, each alias account stores:
- Account identification - Bank account number, branch code, and account type
- Holder reference - Link to the associated holder (Natural or Legal Person)
- Ledger account link - Connection to the underlying Midaz account
- Financial institution details - Bank name, ISPB code, and institution identifiers
- Custom metadata - Additional fields for integration and business-specific needs
Accessing the Alias Accounts page
To open the Alias Accounts page, select the Aliases option from the Accounts section of the left-side menu. The Alias Accounts page displays a table listing all Alias Accounts in your system, including:
- Account Number - The bank account number or identifier
- Holder - The associated holder name
- Account Type - Classification of the account (checking, savings, etc.)
- Status - Current state (Active, Inactive, etc.)
- Created Date - When the alias account was created
If you do not have any Alias Accounts, the list will appear empty with a prompt to create your first alias account.

Common use cases
Linking customer accounts
Linking customer accounts
When a customer opens an account:
- Create a Holder with customer information (Natural or Legal Person)
- Create an Alias Account linking the holder to a Midaz ledger account
- Add bank details (account number, branch, institution)
- The customer can now transact using their familiar bank account number
Multi-bank scenarios
Multi-bank scenarios
When customers have accounts at multiple institutions:
- Create multiple Alias Accounts for the same Holder
- Each alias account references a different Midaz ledger account
- Track different account numbers and bank relationships
- Maintain clear separation between institutional relationships
External system integration
External system integration
When integrating with external banking systems:
- Use Alias Accounts to map external account numbers to internal ledger accounts
- Store institution-specific identifiers (ISPB, participant codes)
- Maintain metadata for integration-specific fields
- Synchronize status changes between systems
Best practices
Create holders before alias accounts
Always create the Holder record first, then create Alias Accounts to link them to ledger accounts. This ensures proper data relationships.
Use consistent account numbering
Follow your institution’s account numbering standards when creating alias accounts to avoid confusion and integration issues.
Keep financial institution details accurate
Ensure ISPB codes and bank identifiers are correct for proper payment routing and regulatory compliance.
Document account relationships
Use metadata to store additional context about account relationships, especially in multi-bank or integration scenarios.
