Ecuador has an agreement, but categories still matter
The DGT includes Ecuador among the countries with exchange agreements. That simplifies the initial question, but it still leaves the details that matter most: how much it costs, whether there are exams, and how the route changes by category.
That is why the first step is not just confirming the exchange exists. It is knowing what type of license you hold and what route that corresponds to in the Spanish system.

The difference between light permits and professional categories
In the official DGT table, cars, motorcycles, and light vehicles without additional testing use fee 2.3 at . Truck or bus categories that require additional tests move into fee 2.1 at 94.05 euros.
