3.2.1. Information request via CESII

Access to the application is offered through the electronic office ( Immediate transfer of information: request New window ). To enter it will be necessary to authenticate with an electronic certificate. The application includes a tutorial.

The user must select the necessary supply from among those authorized.

The request, which will consist of a list of records (understood as a NIF followed by the full name - format: first surname second surname name or company name -), it can be done in two ways:

  • Uploading a file in “.csv” format. It is not necessary to use any special program to prepare the file. Directly, from Excel you can save the document as a “.csv” file. The “.csv” file is a simple type of document to represent data in table form: Columns are separated by semicolons, and rows by line breaks. If you are working with the Excel program, you can save the file with the “.csv” extension. In turn, a “.csv” file can be opened with the Excel program, viewing the information as a table.

  • By directly writing, in a text field, a NIF or several NIFs one per row (separating the NIF from the full name/company name with a semicolon).

    Depending on the supply selected, the maximum number of records requested in each request will vary. This number will be specified in the web application.
