Common questions
Quick answers to common questions about our Spanish DNI OCR API.
How can I get the best accuracy?
To ensure the highest extraction quality, use high-resolution pictures with good lighting and always include both the front and back side images of the document in your request.
Does it support one side of the document?
Yes, but processing only one side will result in lower accuracy and might miss important information that is only present on the other side.
Does it support old versions of the document?
Yes, it supports any version of the Spanish ID Document (DNI), including the older pre-electronic versions.
Does it structure the DNI address?
Yes, it extracts and structures the address into specific fields including road type, road name, number, floor, door, province, municipality, and town.
Does it support NIE documents?
Partially yes. When the document is a NIE (Tarjeta de Identidad de Extranjero), the NIE number is returned in the foreign_id_number field. For DNI documents, foreign_id_number is null.
