🇮🇪 UK SEDOL Coverage

SEDOLs identify not only London Stock Exchange securities but also Alternative Investment Market (AIM), Irish Stock Exchange, and Channel Islands listings. They're mandatory for UK pension fund reporting and HMRC tax filings. Many global depositary receipts (GDRs) and offshore funds also receive SEDOL codes for UK investor access. This broad coverage makes SEDOLs essential for UK portfolio management.
