Step 1

Data sheet

Take your time filling in these details. We will use them solely to process your registration with Social Security and Hacienda and your digital certificate.

Tell us in a few words what you are going to do: it helps us choose the right IAE code and advise you better from day one.

Step 2

Documents to attach

We need these three photos to verify your identity and process your registration and digital certificate.

  • All details must be clearly visible, with no glare or cropping.

  • Same quality as the previous photo.

  • Hold your ID next to your face; both must be clearly visible.

Quick tips: use good natural light, avoid direct flash and check the photo is sharp before sending it.

You can also send us your details and photos via WhatsApp or by email.
