Pattern

regexengine-agnostic
^[A-Z]{6}[A-Z0-9]{2}(?:[A-Z0-9]{3})?$

Raw source: ^[A-Z]{6}[A-Z0-9]{2}(?:[A-Z0-9]{3})?$

How it works

[A-Z]{6} matches the bank-and-country prefix. [A-Z0-9]{2} matches the location code. (?:[A-Z0-9]{3})? optionally matches the 3-character branch code, allowing both 8-char head-office BICs and 11-char branch BICs.
