# Account lists from official registries and the open web

> Demander builds account lists from official business registries in 19 countries, open data and the open web, finds each company’s website, ranks it by persona fit and finds people role by role, with opt-outs and GDPR notices handled in code.

A prospect list starts from a persona: industries, company size and countries. A run asks each country’s official registry first, then open data, the open web and any data provider you connect, merges the records that describe the same company, finds its website and ranks it by fit.

## Sources, in the order a run uses them

| Source | Coverage | What it adds |
| --- | --- | --- |
| Official registries | Czechia (ARES), UK (Companies House), Norway (Brønnøysund), France (Recherche d’entreprises), Denmark (CVR), Finland (PRH), Sweden (Bolagsverket), Slovakia (RPO), Greece (GEMI), Croatia (Sudski registar), US (SEC EDGAR) | Search by industry code, place, legal form and size where the registry supports it; registry ids and registered addresses |
| Registry index | Estonia, Singapore, Belgium, Sweden | Bulk files imported and searched locally; Sweden from the weekly high-value dataset files, every legal person by SNI code, legal form and place |
| Lookup registries | Poland (GUS REGON), Australia (ABN Lookup), Switzerland (Zefix), Canada (Corporations Canada), Ireland (CRO) | They cannot search, so they verify the merged candidates of their country and drop dissolved companies |
| Open data | Global: GLEIF and Wikidata | Legal entity identifiers, official websites and headquarters |
| Open web | Global, no key needed | Company homepages, read politely, with confidence and an evidence URL for every field |
| Data providers | People Data Labs (companies and people) and Hunter (people and e-mail verification) | Your own key and credits; used last |

The list shows the source plan per country and warns where coverage is thin. Most registries are free, though many need an API key of their own. Industry codes from NACE, UK SIC, ISIC, NAICS and ANZSIC are mapped to one set of industries.

## What a run does

1. **Plan and search.** Sources are chosen per country and searched with the persona’s filter: industries, company size, places and legal forms where the registry supports them.
2. **Merge.** Records that describe the same company are merged by registry id, LEI, Wikidata id or domain. Lookup registries then verify the candidates of their countries.
3. **Check opt-outs.** Danish and Swedish candidates are checked against the national marketing opt-out registers, wherever they were found (details below).
4. **Find the website.** Registries rarely carry one. Demander strips the legal form from the name (s.r.o., GmbH, Ltd, Sp. z o.o. and many more), tries candidate domains on the country’s domain and .com, requires each to resolve to a public address and serve a homepage, then matches the name against the page title and site name. Parked pages score zero.
5. **Rank and save.** Companies are ranked by persona fit and saved as accounts with their source, registry id and the date they were found.
6. **Find people, role by role.** For the top companies (20 by default) each buying-committee role is filled with up to five people, one by default, searching only the roles still missing. People come from Hunter or People Data Labs.
7. **Verify e-mails.** Hunter’s paid verifier within the run’s credit cap, otherwise a free check of syntax, disposable domains and MX records. The free check proves the domain accepts mail; it never probes mailboxes, because that looks like abuse to receiving servers.

## Open-web discovery for the rest of the world

Where no registry fits, Demander finds candidate domains from Wikidata official websites, the Tranco list by country domain (when configured, for licence reasons) and the Common Crawl URL index by country domain and hostname keywords. Each site is read politely: robots.txt first, then the homepage, one request per host at a time, identified as DemanderBot, with a 1.5 MB cap. Parked and placeholder pages are skipped.

From each homepage it reads the name, the country (from the JSON-LD address, the domain, the phone prefix and the page language), the industry, size hints, registry ids and B2B signals. A run fetches at most 500 websites and spends at most 180 seconds by default (up to 5,000 sites and 30 minutes if you raise the limits), and reports how many candidates were found, fetched, parsed and matched.

## Opt-outs and GDPR, handled inside the run

- **National marketing opt-outs.** Danish companies with reklamebeskyttelse in CVR and Swedish ones with reklamspärr at SCB are looked up wherever they were found: GLEIF, Wikidata, a data provider or the open web. Opted-out, dissolved and uncheckable candidates are left out, and only the flag is kept, never the register’s data.
- **Lawful basis.** Contacts get legitimate interest only when your workspace’s legitimate interest assessment is complete; otherwise they get none, and outreach refuses them. Prospecting never records consent.
- **Data minimisation.** By default no people are collected in countries where cold B2B e-mail needs prior consent, such as Czechia and Germany. A list option switches that on; the outreach compliance check still applies at enrolment and before every send.
- **Article 14 notice.** Every contact keeps its provider, source reference and the date it was found, and the outbound e-mail footer names the data source.
- **Suppression.** Suppressed addresses and domains are skipped in every run.
- **Gated enrolment.** Prospects reach a sequence only through an enrolment action that passes the gate and the per-country compliance check, and only verified addresses by default.

> **Credits.** Hunter and People Data Labs run on your own key and credits. In live mode every run also stays inside a per-run credit cap (50 by default) and your plan’s monthly prospecting credits; sandbox and dry runs cost nothing. See [pricing](https://demander.to/pricing/).

## From a list to campaigns

Accounts from a list get the usual scores and lifecycle, and their contacts get a buying role, so the [buying committee](https://demander.to/features/personas-and-buying-committees/) coverage shows which roles each account is missing. Fill gaps searches just those roles again.

**Plan ABM campaigns** syncs the list to LinkedIn as a company list and drafts role-targeted campaigns on LinkedIn and Microsoft Advertising. Prospected people are never uploaded to contact-matching audiences such as Customer Match or Custom Audiences, because their data was not collected first-party with consent. Contacts reach [e-mail outreach](https://demander.to/features/email-outreach/) through the same gate as everything else.

## Questions

**Which countries can I prospect in?**

Registries cover 19 countries: Czechia, Slovakia, Poland, Denmark, Sweden, Norway, Finland, Estonia, the UK, Ireland, France, Belgium, Switzerland, Croatia, Greece, the US, Canada, Singapore and Australia. Elsewhere Demander uses GLEIF, Wikidata, the open web and People Data Labs if you connect it, and the list warns where coverage is thin.

**Can I e-mail the people it finds?**

Only through an enrolment that passes the gate and the compliance check for the recipient’s country. Where cold B2B e-mail needs prior consent, it cannot be sent without that consent, and contacts need a completed legitimate interest assessment everywhere else. See [cold e-mail rules by country](https://demander.to/resources/cold-email-rules-by-country/).

**Do I need a data provider?**

Not for companies: registries, open data and open-web discovery need no paid provider. Finding named people and verifying their addresses needs Hunter or People Data Labs on your own key.

**How are Danish and Swedish opt-outs handled?**

Every Danish or Swedish candidate is checked, also when it came from another source: Danish ones in CVR by company number or name, Swedish ones in Bolagsverket by organisation number, which Demander also reads from website footers and VAT ids. If the company has opted out of marketing, or the check cannot be done, it is left out of the list.
