The design shows at the top the map of Andorra with the coat of arms of the Principality highlighted inside it. At the bottom of the design, two opposing arrows interlaced, symbolizing the Customs Agreement between Andorra and the EU, show the years that are being commemorated "1990" and "2015" (the latter is also the year of issue of the coin) and the name of the issuing country. Surrounding the map of Andorra appears the inscription "25th Anniversary of the Signature of the Customs Agreement with the European Union".

The coat of arms of Andorra is the heraldic device consisting of a shield divided quarterly by the arms of the Bishop of Urgell (top left) and the Count of Foix (top right) – who have historically been the two co-princes of Andorra – in addition to the emblems of Catalonia (bottom left) and the Viscount of Béarn (bottom right). At the bottom is the country's motto – Strength united is stronger (Latin: Virtus unita fortior).

A geographical map of Western Europe spans the outer ring and inner core on the right side of the coin. The inscription 2 EURO is superimposed over the map of Europe, with the numeral “2” located in an open field representing the eastern Atlantic Ocean.

12 stars are located on the right side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “O” in “EURO.”

The sequence "2 ★ ★" repeated six times alternately upright and inverted.
