OpenCorporates

Free and paid

The website search box is on the homepage. The pricing page does not put a pound figure on that box. It prices API and bulk delivery. On 18 Oct 2026 Essentials was £2,250 a year (£225 a month) for 500 API calls a month and 200 a day. Starter was £6,600 a year (£660 a month) for 2,500 a month and 500 a day. Basic was £12,000 a year (£1,200 a month) for 5,000 a month and 1,000 a day. Each of those three is marked API only, for internal and external use. Enterprise is “talk to a specialist” for bulk delivery, a bespoke API, and a support plan. Public-benefit access is an application, not a coupon code, for journalists, NGOs, universities, and anti-crime research. Do not describe the £2,250 plan as the price of looking up one company in the browser. Cite the plan only when you mean the API.

The homepage describes fresh, standardized company data from official primary sources across 140 or more jurisdictions, under the project's Legal-Entity Data Principles. It says the database is a single set of company records from over 140 government registries and other official sources, and that the goal is to help a reader understand the companies they deal with. The search form posts to the companies index. The placeholder counted 222,884,745 companies on 18 Oct 2026. A heading said the service is used by over 2,000 companies. Another line said 80 percent of North America and Europe's largest banks use it. That percentage is the page's claim. This listing did not audit it.

• 222,884,745 in the search box. That placeholder was on the homepage on 18 Oct 2026, next to a claim of 140 or more jurisdictions.
• API from £2,250 a year. Essentials is 500 calls a month. Starter and Basic step up. Enterprise is a conversation.
• Public-benefit access. Journalists, NGOs, universities, and anti-crime research can apply. It is not the same as the paid API.

1. 1

   Search a company name on the homepage and open the registry the row cites.

2. 2

   If you need the API, pick Essentials, Starter, or Basic from the pricing page and record the caps.

3. 3

   If the work is public-benefit, use the application path instead of assuming the paid quota.

4. 4

   Reconcile officers and status with the official register before you name a controller.

• You have a company name and no registry. Search it on the OpenCorporates homepage and open the official register the row cites. On 18 Oct 2026 the search box said 222,884,745 companies, and the page said the records come from over 140 government registries. The box count will change. Officers and status on the copy can lag the register. Reconcile them before you name a controller. A row is a lead.
• A developer wants the API. The pricing page is the source, not the search box. Essentials is £2,250 a year or £225 a month for 500 calls a month and 200 a day. Starter is £6,600 a year. Basic is £12,000 a year. Enterprise is a conversation for bulk delivery. Public-benefit projects, including journalists and NGOs, apply for free at-scale access. Do not describe the £2,250 plan as the price of one browser search.
• A TRM Ardence workspace is described as if it included every OpenCorporates field. The 13 Oct 2026 Ardence post names OpenCorporates and says availability varies by customer and jurisdiction. Ask TRM what the agreement includes. Supplemental provider terms may apply. The bank-usage percentage on the OpenCorporates homepage is their claim. This listing did not audit it.
