Sort Code Meaning

A Sort Code is a six-digit number used in the British and Irish banking systems to identify a specific "Bank" and "Branch." It is the domestic equivalent of a "Routing Number" in the US or a "BIC/SWIFT" code in international banking. When combined with an account number, it creates a unique identifier for any bank account in the region.The first two digits identify the "Bank" (e.g., 40 for HSBC or 20 for Barclays), while the remaining four digits identify the specific "Branch Location." While many modern "Digital Banks" (like Monero or Revolut) use a single sort code for all their users, traditional banks still use them to route physical cash and manage local accounting.

This system is the backbone of the BACS and Faster Payments networks in the UK.In the world of "Crypto On-ramps," providing a Sort Code and Account Number is how UK users send "GBP" to an exchange. The exchange's "Settlement Bank" uses these details to instantly credit the user's account via the Faster Payments service.

As fintech moves toward "Open Banking," the sort code is becoming less of a "Physical Branch" identifier and more of a "Technical Address" that allows different financial apps to talk to each other seamlessly.
