Estonian registry code and company data by registry code
Updated 2026-08-20 · 6 min read
The registry code is the unique number of an Estonian company. Names change, addresses change, contacts change constantly — the registry code stays the same.
That makes it the single most valuable field in a sales or marketing dataset: it is the only key that keeps a list clean and duplicate-free.
What the registry code tells you
It is an 8-digit number assigned when a company is registered. It identifies one specific company even when several companies use similar names.
- Unique identifier that never changes
- Required on invoices and contracts
- The key for joining data across sources
- Distinguishes companies with similar names
Company data by registry code
For a single company a public lookup is enough: name, legal form, address, activity and board members are public information.
When you need hundreds or thousands of companies at once, one-by-one lookups stop working. You need the whole target group in one file, with a registry code on every row.
Why the registry code keeps a list clean
Merging a purchased list into your CRM by name or email creates duplicates. Merging by registry code is exact — and lets you download only the delta next time.
- No duplicates on CRM import
- Exclude existing customers from a campaign
- Refresh data without losing records
- Attribute campaign results to a specific company
