Insights on this address

Building with many business tenants

10 companies are registered here now. They are based in a building of about 420 m² of floor space. That is about 42 m² per company, room enough for an office each. Most are not tied to one another and rent independently in the same building.

  • This address has more companies than 95% of Belgian addresses, which have at most five.
  • The address register knows 4 box numbers for this entrance, against 10 registered companies.
  • 7 have their registered office here, 3 only an establishment or branch.
  • The most common main activity is Other manufacturing (32200), at 1 of the 6 current companies with a known activity (6 different). Then come Retail trade (47712): 1, Retail sale of antiques (47791): 1.
  • None of the 8 companies here shares a current director with another.
  • Half of the current companies have been registered here for less than 12 years.
  • 1 company is dissolved or no longer in the register. 1 other moved away and still exists.

Recommendations

  1. Open the dossier of the company you are interested in. The list shows whether it has its registered office here or only an establishment.
  2. Look at how the former companies ended. That says something about the address, nothing about any individual company.
Method and limits of this check

A shared address is not suspicious in itself. Office buildings, accountants and business centres host many companies. The verdict is about the kind of address, not about any individual company.

The comparison rests on all 1,408,687 active Belgian addresses. Half of them have one company, 95% at most five, 99% at most ten and 99.9% at most 35. There is no national reference for bankruptcies and new registrations. So they are shown here as counts.

A shared director holds a current board mandate at two companies at this address. Statutory auditors and liquidators do not count.

Floor area and storeys are not measured anywhere. So the building shows them as estimates, next to the measured footprint. No register of building use (office, housing) is available.
