Test item supply
  • You will receive your test item supply every week.
  • The supply contains the test items to be sent for the next week. The test items are addressed and pre-franked.
Sending of test items
  • Please note that it is very important for the survey that you try to send the test items always on the planned date. For general documentation it will be helpful to note down the actual posting date on your posting plan.
  • Please send the test items by dropping them into a mailbox on the street and/or from the counter at your post office.
Test items with customs forms CN22/CN23 or aviation security declaration forms
  • The test items are all handled as letters (including the small boxes). For some countries the content of larger formats has to be declared for customs. This will be done by using the CN22/CN23 customs form. These forms are already filled in on your test items (content: documents, weight: 200g, value: 1€ or 0€). Please see the example below.
  • Some test items need to be sent with an aviation security declaration form. These forms are already filled in on your test items (content: documents, sender’s name and address). Please see the example below.
  • Please fill in the date and sign the form (CN22/CN23 or aviation security declaration) before sending it. This is very important.

Your Online Account (Panel Zone)

Please log in to your online account: https://nu-mms.ipc.be/mmu-panel-zone/login/login.htm

Once you have successfully logged in to your account with your Panellist ID and password set by you, the following Welcome Page will be available. It will give you an overview of all important functions.

Sender pack Registration

After you have received your weekly sender pack (test letter supply), please confirm the receipt in your online account before you start sending items. Please click on ‘REGISTER RECEIVED SENDER PACK‘ and enter the 5-digit Sender Pack ID (you will find it on the respective printed posting plan in the right upper corner). Then click ‘Submit‘.

A new page will open asking you when you received the sender pack. Please select ‘Today’, ‘Yesterday‘ or ‘Other date‘ and click on the little calendar to enter the date you have actually received the Sender Pack and click ‘Submit‘.

Please note: You will not be able to regsiter your sent items if your Sender Pack has not been registered previously.

Data entry Posting

After you have sent the test items, please confirm the actual sending date in your online account. For the progress of the study it is very important that you enter the data the same day as you send the items.

You will send 3 – 5 test letters per week on average. By clicking on ‘POSTING PLAN’, you will see the exact number and planned dates of posting in chronological order. For entering posting information, please click ‘Send’.

A new page will open, please select the ‘Actual Send Date’, enter the ‘Exact Send Time’ and select your ‘Sending Location’ and then click ‘Submit’.

To avoid mistakes, please enter the sending date only after having sent the test items.

Please note: If you were not able to send a test item on the planned date, it is possible to adjust the send date. In this case, please follow up with sending it on the same weekday of the following week and fill in this date as the actual sending date.

Data entry Receiving

You will receive 3-5 test letters per week. You can see the exact number and from which country they are in your online account under ‘RECEIVING PLAN‘.

For the correctness of the collected data it is very important that you empty your mail box on a daily basis in the late evening. Please check you cover letter for exact information on the latest possible delivery of mail in your country. Furthermore, it is essential that you enter the data the same day as you receive the items.

Please make sure to always note the receipt date and week day on the item when you empty your mail box. Additionally, please keep all test letters including the envelopes for 3 months. Within the retention period of three months and in individual cases we may ask you questions concerning a specific test letter.

The test letters are of four different formats – small and big letters, thick envelopes and small boxes.

In case you are not present during the delivery of a thick envelope or a small box, your postal service provider will notify you about the delivery attempt. Normally, you will receive this notification in the form of a card in your mail box. If you have a special agreement with your postal service provider, you may also be informed by SMS or e-mail.

When you received a notification, please do always take a picture, in case it is for a test item. If the notification was for a test item, please upload the notification before registering the received item. Please click on ‘UPLOAD NOTIFICATION’.

Select the date when you received the notification. If you cannot remember when you received the notification, please click on ‘Unsure’. Use the text box to write down the number of the corresponding test items and if needed a comment to an unusual event.

To upload the picture of the notification, please click on ‘Search’ (this button may be in your local language, depending on your browser settings), select the photo of the respective notification and upload it. The photo will appear. If it is the right one click ‘Submit’.

Please do remember that the notification details do not suffice; the test items still need to be collected and the details must be entered online.

After you have received the test items (with or without notifications), please confirm the receipt date (resp. the date you have collected the item) in your online account.

Please click on ‘REGISTER RECEIVED ITEM’, enter the Control ID / Identification Code which you can find on the document inside the test item and click on ‘Search’.

Now please enter the correct receipt date. If you cannot remember the exact receipt date, please click ‘Unsure’. If you have received a notification for the respective item, please link the notification with the item by ticking the corresponding box (circled in red in the picture).

When confirming the receipt of the thick envelopes and small parcels (bulky items) online you have to select the delivery place by clicking one of the options given online. Please read the following explanations, as some of the options can be misunderstood easily.

General information regarding the receipt of small parcels (bulky items) and big envelopes

Please make sure to always choose the correct delivery option for the small packets and big envelopes.
Only when you enter the notification BEFORE you enter the Control ID, the system will allow you to match the test packet with the notification. This way we receive the exact date when you actually received the notification and the date when you actually picked up the packet.

Please find more detailed information on delivery options (with and without notification) hereafter.

Delivery Options

In case you receive a damaged item, please inform us by email/message and upload or mail us a photo of that item – after entering the receipt date online as usual.

Item Queries

After having entered a sent or receipt date, you might receive an item query, if the data differs from the planned send date or if any other data related queries occur. This will be shown directly at the home page of your online profile at the upper part of the page.

Please Click on ‘Resolve Item Queries‘ and fill in the outstanding data.

Sender Query

In case a query has been raised for an item which you have sent, you are asked to fill in the date, time and location as indicated in the screenshot above. After  you have checked the data carefully, please click ‘Save‘. Should you not be sure of the data you have entered, please click ‘I don’t know anymore‘.

Receiver Query

If the data you have entered for received items has been queried, you are asked to check the date when you received the item (as shown above). Please fill in the date and click on ‘Save‘ if you are sure about the date. If you are not sure about the date, please click on ‘I don’t know anymore‘.

Please note: To make sure that the data you have entered is correct, we kindly ask you to always note down your sent dates on your posting plan, and the receipt dates of every test item.

Not available to Send/Receive

Ideally you are available during the entire duration of the survey or you can delegate the task to another person in the case of absence or illness. Please inform us immediately about any duration when you won’t be able to send test items (e.g. change of address, absence, holidays, …).

Please click on the button ‘NOT AVAILABLE TO SEND/RECEIVE’ and thereupon on ‘+Add’.

Now fill in the start and end date and the reason. If you are unavailable for a whole week, please make sure to also include the weekend when entering the end date.

If you have a cover who can do the tasks when you are not able to, please select the box ‘Covered by someone else’. A cover helps us to meet our target of sending a certain number of test items from your postcode area during the year in order to make our findings statistically valid.

The section ‘Person who will cover me’ opens. Please fill in the required information – Name, Phone Number and Email – and click on ‘Save’.


Anyone who is over the age of 18 can cover you as long as they can perform the tasks exactly as you do: receive the sending supply, sent out test items, empty the mail box every day and enter data online. A family member, your house mate or neighbor, or someone who will feed your cat, for example, may cover you. They will need access to your house to receive the test item supply and empty the mail box, and will need to send items from the same postcode area as you do. Please instruct them in detail and make sure they understand how to carry out your UNEX tasks before you go.

If you do not have a cover, please make sure to inform us about your absence at least six weeks in advance. In this way we can adjust the production of test letters and you will not receive any test item supply when you are away.

If you wish to add another period where you are not able to send, simply repeat the above mentioned procedure.


Sending location Registration

When activating your online account, you have already entered your sending location. In case your sending location changes or you want to add another one, please add the new sending location here.

You can do this by clicking on ‘SENDING LOCATION REGISTRATION’ and thereupon on ‘+Add’.

Please fill in the information of the sending point you will use to post your test items – you can add several sending locations, both Mailbox AND Post Office, even if the induction method is specified as ‘Mailbox’ resp. ‘Post Office’.

Please note that you need both, a Mailbox and a Post Office, as the small boxes usually cannot be sent from a Mailbox. Simply fill in the description field (e.g. ‘Mailbox at the corner’; ‘Post Office near Metro Station’) and indicate the respective post code (if you are not sure about the post code, please use your postal operators website to research).

Please also indicate the last collection time of your sending location. Usually, these times are displayed on the Mailbox or in the Post Office (please also check the ‘Any questions’ section below). If on a certain day (e.g. Sunday) there is no collection at all, please select the respective box. Once completed, please click on ‘Save’.

Your sending location is now submitted and will appear in the Overview under ‘Unapproved senderpoints’. We will review it shortly. Once confirmed, it will appear under ‘Approved senderpoints’ and you can use it to register items.

If you wish to add another sending location, simply repeat the above mentioned procedure.

Change address

If you are moving, please let us know at least six weeks in advance, so that we don’t continue sending test item supplies to your old address. It is easy to let us know, just click on ‘CHANGE ADDRESS’ and choose if you stay within the same country or if you move abroad.

If you move abroad, you will then need to contact us directly. If you stay within the same country, please follow the next steps. Enter the date when the new address will be valid and your new postcode and click ‘Next’.

Please enter your new address according to the sample address on the right and click ‘Submit’. It is not necessary to enter the country name.

Please check if your new address has been entered correctly. If so, please click on ‘Confirm’ Otherwise, please click ‘Back’ and correct the new address.

Please note: If you have redirected your mail from your old address, please enter all redirected test items as ‘unsure’ as the redirection normally delays their delivery process. As a sender, you may need to set up a new sending location, in case your postcode changes.
