Louizalaan 523
Domiciliation address or business centre
315 companies are registered here now, in a building of about 14,700 m² of floor space: about 47 m² per company. Most are not tied to one another. Fewer than 0.1% of Belgian addresses have as many; with so little space per company and so few ties, that is what a letterbox address or business centre looks like.
- More companies than at 99.9% of Belgian addresses (which have at most 35).
- 130 have their registered office here, 185 only an establishment or branch.
- Most common main activity: Business and other management consultancy (70200), at 41 of the 268 current companies with a known activity (109 different). Then Computer consultancy and computer facilities management (62200): 15, Activities of lawyers (69101): 15.
- 2 of the 299 companies share a current director with another company here; the largest group has 2.
- Half of the current companies have been registered here for less than 8 years.
- 12 new registrations in the last twelve months (66 in three years).
- 59 companies went bankrupt, 43 of them while registered here.
- 1 company was granted a judicial reorganisation.
- 27 companies are dissolved or no longer in the register; 59 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.
