🇬🇬Guernsey

New to the API? Start with the jurisdictions overview, which explains how ordering, identifiers and documents work everywhere.

Company data here comes directly from Guernsey Registry.

What you can call here

What each operation does is the same everywhere and is explained on the jurisdictions overview.

How to search

Start with company search and jurisdictionCode: "gg". Pass the name as companyName, a registration number as companyNumber, or both to narrow the result. Here companyNumber is read as registeredNumber.

Fields

To say exactly what you mean, send an advancedQuery instead. Guernsey understands these fields:

Examples

{  "jurisdictionCode": "gg",  "advancedQuery": {    "registeredNumber": "CMP14169"  }}

Search notes

• The company-name search field only ever matches against a company's registered name — it is never compared against registration numbers. Typing a registered number (for example a value shaped like "CMP14169") into a plain name search will return no results; once you know a company's registered number, use it to fetch that company's report directly rather than searching by name for it.
• Guernsey company search does not cap or page results to a requested limit — a broad name search can return every matching entity the registry holds rather than a bounded first page. Apply your own client-side limiting if you need to bound the result count; do not assume the API truncates the list for you.

Company identifiers

Search by passing the registration number as companyNumber — it is matched against the schemes this register can search on, so you do not name the scheme yourself. Not every scheme below is searchable; the rest label the values returned in a company’s identifiers.

Documents you can order

Nothing can be ordered in Guernsey yet. These are the documents the register will expose once they are live.
