In order to facilitate and accelerate the investigation of claims and the payment of benefits, the institutions to whose legislation a person has been subject shall:
(a)
exchange with or make available to institutions of other Member States the elements for identifying persons who change from one applicable national legislation to another, and together ensure that those identification elements are retained and correspond, or, failing that, provide those persons with the means to access their identification elements directly;
(b)
sufficiently in advance of the minimum age for commencing pension rights or before an age to be determined by national legislation, exchange with or make available to the person concerned and to institutions of other Member States information (periods completed or other important elements) on the pension entitlements of persons who have changed from one applicable legislation to another or, failing that, inform those persons of, or provide them with, the means of familiarising themselves with their prospective benefit entitlement.

For the purposes of applying paragraph 1, the Administrative Commission shall determine the elements of information to be exchanged or made available and shall establish the appropriate procedures and mechanisms, taking account of the characteristics, administrative and technical organisation, and the technological means at the disposal of national pension schemes. The Administrative Commission shall ensure the implementation of those pension schemes by organising a follow-up to the measures taken and their application.
3. For the purposes of applying paragraph 1, the institution in the first Member State where a person is allocated a Personal Identification Number (PIN) for the purposes of social security administration should be provided with the information referred to in this Article.
