Notes

• Company Number Normalization: Standard English company numbers are 8 digits long with leading zeroes preserved (e.g., 00048839). Scottish corporations begin with SC, Northern Irish companies with NI, and Limited Liability Partnerships with OC.
• Global LEI Integration: When available, the response cross-references the 20-character ISO 17442 Legal Entity Identifier (lei) associated with the entity for financial reporting compliance under MiFID II and EMIR.
• Corporate Filings: The publicNotices list includes the latest confirmation statements, account filings, and status changes recorded by the official corporate registry.
