Union of International Associations - UIA is an international non-profit association (IVZW in Dutch / AISBL in French). IVZW/AISBL is reserved for non-profits with members or activities across multiple countries; incorporation is by royal decree under Title 10 of the CSA/WVV. Brussels hosts a high concentration of IVZW/AISBL headquarters because of its role as host city for the European Union institutions and many international NGO secretariats. It is registered with the Crossroads Bank for Enterprises (Kruispuntbank van Ondernemingen / Banque-Carrefour des Entreprises), with KBO number 0408.287.747.

You can verify Union of International Associations - UIA's legal status in three ways. First, look up the KBO record directly: https://kbopub.economie.fgov.be/kbopub/zoeknummerform.html and enter 0408.287.747 (or 0408287747). The result page shows the official name, legal form, address, status, and registration date. Second, look up the most recent annual accounts at the National Bank of Belgium Central Balance Sheet Office (https://consult.cbso.nbb.be/consult-enterprise) using the same KBO number - Belgian non-profits above the small-association threshold (around €312,000 in revenue, or any with paid staff) are legally required to file there each year. Third, every legal-form change, board appointment, statute amendment, dissolution and registration appears as a public notice in the Moniteur belge / Belgisch Staatsblad (https://www.ejustice.just.fgov.be) - searchable by KBO number. If those three sources agree on name, address and current legal form, the organisation is legitimate.

You can donate to Union of International Associations - UIA directly through its donation page (https://www.uia.org/en/membership/supporter#donate). Belgian charities typically accept domestic transfers via Bancontact, SEPA bank transfer, and online payment processors (Mollie, Stripe). A large share of larger Belgian charities channel donations through the King Baudouin Foundation (KBS-FRB / kbs-frb.be), which administers project funds and issues the fiscal certificate on behalf of the recipient charity. International donors can give by SEPA transfer (Belgium is in the eurozone, so intra-EU transfers are inexpensive), PayPal, or fundraising platforms common in Belgium such as iRaiser, HelloAsso, Donorbox, and GoFundMe. Always confirm the recipient's IBAN and KBO/enterprise number before sending funds, and ask the organisation to send the fiscal certificate (fiscale attest / attestation fiscale) for donations of 40 euros or more if you intend to claim the 45% tax reduction.
