I cannot send my parcels via a PostNL parcel and letter machine, why is that?

When sending or returning your parcels via a parcel and letter machine, you need a PostNL ID. If you don't have a PostNL ID yet, no worries, you can easily create one by following these steps:

1. Download or open the PostNL App and log in with your personal account.

2. Go to 'Account.'

3. Tap on PostNL ID at the top, and then on Create PostNL ID.

4. Go through the iDIN process to verify your details and receive your own PostNL ID.

After this, you can scan your package at the parcel and letter machine using your PostNL ID, and you do it as follows:

1. Scan the label on the package.

2. Scan your PostNL ID.

3. Send it off!
