Permanent Acts

Constitution

The Constitution is the basic Act of the Union. It contains the organic rules of the Union and is not subject to reservations.

The Constitution currently includes ten Additional Protocols.

Non-permanent Acts

Universal Postal Convention

The Universal Postal Convention and its Regulations embody the rules applicable throughout the international postal service and the provisions concerning the letter-post and postal parcels services. These Acts are binding on all member countries. Member countries must ensure that their designated operators fulfil the obligations arising from the Convention and its Regulations.

Postal Payment Services Agreement

The Postal Payment Services Agreement, its Additional/Final Protocol, and its Regulations are binding only on the countries that are parties to the Agreement.

The Agreements of the Union, and their Regulations, regulate the services other than those of the letter post and postal parcels between those member countries which are parties to them. They are binding on those member countries only. Signatory member countries must ensure that their designated operators fulfil the obligations arising from the Agreements and their Regulations.

The Regulations, which contain the rules of application necessary for the implementation of the Convention and of the Agreements, are drawn up by the Postal Operations Council, bearing in mind the decisions taken by Congress.
