Test item supply

  • You will receive your test item supply every week.
  • The test items are addressed and pre-franked with stamps.
  • The supply contains the test items to be sent for the next week. It might occur that you receive some items that include transponders. The procedures explained in our instructions are always the same, no matter if these items include transponders or not.

Please note: It is important that you stick to the franking method that is mentioned in our cover letter. Please do not use any other method.

Sending of test items

  • Please note that it is very important for the survey that you 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.
  • Depending on the induction method mentioned in our cover letter, please send the test items by dropping them into a mailbox on the street or bringing them to the counter at your post office.

Please note: It is important that you stick to the induction method that is mentioned in our cover letter. Please do not use any other method. (For further information about the induction method, you can also check our FAQ section.)


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 features.

Data entry

After having 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 on the same day as you send the items.

You will send 3 – 5 test letters per week. By clicking on ‘POSTING PLAN’, you will see your planned postings including the exact number and planned dates 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.

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 the items. Please click on ‘Register Received Sender Pack’ and enter the planned posting date of one of the items in your received sender pack. Then click ‘Submit’.

Item Queries

After having entered a sent date, you might receive an item query, if the data entered 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 see picture below).

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’.

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

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 period in which 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 as well as the reason.

If you have a cover who can perform 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’.

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

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, send out test items 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 will need to send items from the same postcode area as you do. It is important that they are able to receive the test item supply and they 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.

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 so 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 for the option Post Office, but please make sure to always stick to the induction method as specified in our cover letter. Simply fill in the description field (e.g. ‘Mailbox at the corner’; ‘Post Office near Metro Station’ or ‘Pick up by national postal service provider’) 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 ‘Possible 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’.

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 by clicking on ‘CHANGE ADDRESS’ and choose if you either stay within the same country or move abroad.

In case you are moving abroad, you will 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 the new address has been entered correctly. If so, please click on ‘Confirm’. Otherwise, please click ‘Back’ and correct the new address. (If you are a business sender, this only applies in case your company is moving.)

Please note: As a sender, you may need to set up a new sending location, in case your postcode changes.
