Mouscron
Ville de Mouscron — Service Permis-Passeports et bureau d’enregistrement local
Rue de Courtrai 63, Centre administratif, 7700 Mouscron
Apply at the main administrative centre rather than a neighbourhood branch, and book ahead on some days of the week.
Bring a recent colour passport photograph taken less than six months ago and your previous passport, or the Belgian police loss/theft report if it is missing. Ask which identification and child-authorisation documents are needed in your circumstances. Confirm current fees with the service, as there is no fixed amount to rely on.
