No, a KVK number cannot be changed. Organisations are registered within Portbase based on their KVK number and the associated official details as recorded by the Kamer van Koophandel. It is not possible to deviate from this.
If an organisation continues under a new KVK number, for example as a result of a merger, acquisition or restructuring, the existing account cannot be converted to the new KVK number. In that case, a new register must be completed for the new organisation using the new KVK number. In this case, register a new organisation and request your services again.
In the event of a merger of several organisations, it is therefore unfortunately not possible to merge the organisations within Portbase either. Existing registers remain linked to the original KVK number and cannot be merged or transferred to another KVK number.
