The thirty-six territories that support SEPA greatly boost the economic capacity of the region. At the moment, the SEPA zone consists of twenty-eight EU member-states: Germany, France, Estonia, Belgium, Spain, Denmark, Italy, Greece, Finland, Hungary, Austria, Slovenia, Ireland, Bulgaria, Malta, the Netherlands, Lithuania, Poland, Croatia, Portugal, Sweden, Cyprus, Latvia, Romania, the Czech Republic, Luxembourg, Slovakia, and the United Kingdom.

However, SEPA is not only about the EU countries. Such territories as Norway, Iceland, Liechtenstein, Switzerland, Andorra, San Marino, and Monaco, are also part of the network.

Considering the population of the above-mentioned states, almost half a billion people reside in the SEPA area and generate more than 120 billion SEPA transactions each year.

This makes SEPA the primary means for Euro transactions in the EEU. All citizens and businesses residing or possessing bank accounts in the countries of the SEPA zone can enjoy international Euro transactions of the same speed and convenience as the ones executed domestically.
