Insights on this address

Domiciliation address or business centre

164 companies are registered here now, in a building of about 9,400 m² of floor space. That is about 58 m² per company. Most are not tied to one another. So little space per company and so few ties fit a letterbox address or business centre.

  • This address has more companies than 99.9% of Belgian addresses, which have at most 35.
  • The address register knows 11 box numbers for this entrance, against 164 registered companies.
  • 135 have their registered office here, 29 only an establishment or branch.
  • 2 of the 161 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 5.4 years.
  • This address had 16 new registrations in the last twelve months (55 in three years).
  • 2 companies went bankrupt while registered here.
  • Of the companies founded from 2018 to 2020 with their seat in postcode 1831, 13.6% went bankrupt within five years. For Belgium as a whole that is 6.5%.Survival tables
  • 4 companies are dissolved or no longer in the register. 5 others moved away and still exist.

Recommendations

  1. 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.
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.

The list of an address holds the companies in the KBO register and those that left it since April 2026. A company that stopped before then is not in it. So the bankruptcies at this address are shown as counts. The comparison with Belgium runs over the postcode, for the same founding years and after the same number of years. It comes from the survival tables, which start from the founding deeds in the Belgian Official Gazette and count the companies that stopped too.

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.
