Working Abroad (Wabro) - online service

Before you start

What is Working Abroad?

Working Abroad is an online service through which an employer can request an A1 Attestation or a Certificate of Coverage when posting a Belgian employee abroad for a limited time. Normally speaking, employees are covered by the social security legislation of the country where they work. An A1 Attestation or a Certificate of Coverage will serve to prove that Belgian social security remains applicable to a Belgian employee posted outside of Belgium.

How to get access to secure online services

Working Abroad is a secure online service. This means that you need to request a secure access to the Belgian Social Security – Enterprise portal in order to use it.

  1. Go to the registration page of the Social Security – Enterprise portal (in French) and click on the option for companies registered as employers (Mon entreprise est enregistrée comme employeur).
  2. Click on the option I want to manage my obligations towards the NSSO myself (Je souhaite traiter moi-même mes obligations administratives envers l’ONSS) on the NSSO registered companies page on the Social Security – Enterprise portal (in French).
  3. Follow the guidelines and assign a Chief Access Manager in CSAM. CSAM is available in English.

Employee data you need in order to make a request in Working Abroad

In order to request a document for a Belgian employee in Working Abroad, you will need the following:

  1. The employee’s Social Security Identification Number (SSIN). In Belgium, this number is identical to the ‘identification number of the National Register’ to be found on the back of the employee’s Belgian ID card.
  2. A Dimona declaration proving that the employee is in your employ at the time of the posting. Dimona is the online service in which you must declare every person entering or leaving your employ.

We recommend also activating your e-Box Enterprise, which will make an exchange of documents with the National Social Security Office (NSSO) much easier.

How to log in to Working Abroad

  1. Click the button in the menu of the 'Working Abroad' page of the Social Security – Enterprise portal (in French).
  2. You arrive on the access page to the secure services. Choose your preferred login method to access Working Abroad.
  3. You arrive on the Working Abroad home screen.

What actions can you undertake in Working Abroad?

Homescreen - Working Abroad Homescreen

 

You can do the following in the online service:

  1. Request a posting abroad (Posting request). This is where you request a certificate of coverage if your employee is going to work in one country that is not Belgium, for a precise period of time.
  2. Request employment in multiple countries simultaneously (Simultaneous occupation request). This is where you request a certificate of coverage for an employee who is going to work in several countries at once during a given period (Belgium + another country, or several countries that are not Belgium).
  3. Request a voyage for a seafarer (Request seafarers)
  4. Consult your requests (Consult a request)
  5. Cancel a request (Cancel a request)
  6. Search existing requests made by your organisation.

How will your request be processed?

The online service will take you through four steps in order to request an A1 or Certificate of Coverage for an employee.

Once your request has been registered in the online service, the NSSO will check it.

If the posting is validated, you will receive an A1 Attestation or a Certificate of Coverage in your e-Box Enterprise.

Request a posting abroad under the ‘Posting request’ tab.
