I can generate a standard record lay-out file with data on a given quarter. How can I mail this file to Statistics Netherlands?

You can upload this file to Statistics Netherlands. You do not need any specific software for this. You can upload files by creating a secure link to Statistics Netherlands through your internet browser. The HTTPS protocol (Hypertext Transfer Protocol Secure) takes care of a secure data exchange via the Internet.
Uploading files requires a survey code, name and password. If you want to use the upload facility please email bedrijveninfo@cbs.nl, with subject IDG. In this email you should also include:
Statistics Netherlands registration number,
Name of the company PSI/Agent,
Address of the PSI/Agent,
Name, email address and telephone number of the contact.
We will then email you the survey code, login name and password as well as the internet link.
