What Are Virtual IBANs?
Virtual IBANs are unique International Bank Account Numbers assigned to clients or transactions that all route to a single underlying bank account. They provide the appearance and functionality of individual bank accounts without requiring separate accounts for each client.
Think of virtual IBANs as intelligent mailboxes: while all mail goes to the same building (your master account), each mailbox (virtual IBAN) has a unique address that identifies who the mail belongs to.
How Virtual IBANs Work
The Technical Architecture
Virtual IBAN systems involve several components:
Master Account:
Your main bank account that holds all funds. This is a real account at a licensed bank with full banking capabilities.
Virtual IBAN Layer:
A layer of unique IBANs that map to your master account. Each virtual IBAN is valid for receiving transfers but isn't a separate bank account.
Routing Engine:
When payments arrive at any virtual IBAN, the routing engine identifies which client the payment belongs to based on the IBAN used.
Reconciliation System:
Automatically matches incoming payments to clients, eliminating manual reconciliation.
Payment Flow Example
Here's how a typical transaction works:
1. Client A receives their unique virtual IBAN: GB82WEST12345698765432
2. Client A's customer sends a payment to this IBAN
3. The payment arrives at your master account
4. The system identifies it as Client A's payment based on the virtual IBAN
5. Client A's balance is credited automatically
6. Full audit trail is maintained
