Beware of fraud attempts!

Currently, fake Koelnmesse invoices are being sent by email and fraudulent calls are being made. The criminals use manipulated phone numbers – including official interzum hotlines – and email addresses that look very similar to the official ones.

Important information:

interzum does not offer any telephone discount promotions.

Check your invoices carefully and do not make any payments on suspicious claims.

Official invoices are sent exclusively by services@exhibitor.koelnmesse.de.

Inform us of any suspicious activity.
