How to interpret an address cluster
What the cluster shows, how to read the signals and what to verify
An address cluster is an address with an unusually high number of registered companies. This guide explains how to read the cluster, which signals are relevant and how to avoid drawing overly broad conclusions.
Step by step
Open the address cluster ranking
Go to the address cluster tool. The ranking shows addresses sorted by number of active companies. Filter by company type (e.g. AB, HB) if you are looking for a specific pattern.
Click an address to open the detail panel
The panel shows signals: number of active companies, inactive companies, new companies in the last 12 and 24 months, registration period and company type distribution. These are facts from the register, not risk assessments.
Read the company list
Scroll through the companies. Are most in one company type (e.g. limited companies)? Do many have similar registration years? This may indicate batch registration, which can itself have legitimate explanations.
Compare with the address on the map
The map plots clusters geographically. An accounting or law firm is often clearly visible if you compare addresses in a business district. A P.O. box address may look different on the map.
Verify manually if you intend to publish
Cluster data is a starting point. Source verification should be done directly in the Bolagsverket register, at UC, in annual reports or via direct contact with the companies.
Method and limitations
Address clusters are based on the Bolagsverket register. A shared address does not prove ownership, control or wrongdoing. Cluster ranking shows observable patterns, not conclusions about legality or misconduct.
Frequently asked questions
What is an address cluster?
An address cluster is an address with an unusually high number of registered companies. It may be accountants, law firms, coworking spaces or P.O. boxes. The cluster is an observable data point, not evidence of wrongdoing.
How do I know if a cluster is unusually large?
The national ranking shows the ranking. An address in the top 50 has a significant cluster. Also compare with the signal panel: the proportion of active companies and registration rate provide additional context.
