Until September 2008, the period for granting Social Welfare benefits between the MERCOSUR countries was very long, since the documents were sent by means of paper forms via conventional mail. For this reason, there was no automated control of the documentation sent or received, which prejudiced efficiency and compromised security, principally in regard of control and monitoring of the exchange of information, causing harm to those covered and generating high costs of managing the process.

As globalization has enabled various kinds of international exchanges to take place more frequently, the number of companies entering into other markets, detached workers, and migrants have increased. Accordingly, an increase in pension contributions made overseas has followed. In this regard, the National Pension Service (NPS) promoted social security agreements with the aim of reducing the contribution burden on companies and dispatched workers while protecting eligibility for benefits that were made overseas.
