6 new registrations in the last twelve months (29 in three years).

9 companies are dissolved or no longer in the register; 15 moved away and still exist.

What you can do with this

For one company at this address: open its dossier and check whether it has an establishment elsewhere. That is most likely where it actually operates.
Ask the company where it works and who receives its mail. A registered office in a business centre is allowed and is not a bad sign in itself.
Look at staff and fixed assets in its annual accounts: they show whether there is real activity behind it.

What this check does and does not say

A shared address is not suspicious in itself: office buildings, accountants and business centres host many companies. The verdict says what kind of address this is, nothing about any individual company.

The comparison rests on all 1,408,687 active Belgian addresses: half have one company, 95% at most five, 99% at most ten, 99.9% at most 35. There is no national reference for bankruptcies and arrivals; they are shown here as counts.

A shared director is 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: the building shows them as estimates, next to the measured footprint. No register of building use (office, housing) is available.
