Questions

What people ask about the e-CPF OAB.

Does it work in every court?

ICP-Brasil certificates are accepted by electronic case systems (PJe, e-SAJ, Projudi, eproc and others). Some systems require an A3 token or their own plug-in — our team helps with the setup.

Can a whole law firm get certified together?

Yes. We schedule validation for the firm's lawyers back to back, by video or in person. Contact us on WhatsApp.

How long does it take?

The certificate is issued immediately once validation is approved. Customers who buy in the morning with their documents in order are usually signing the same day.

Do I need to travel to Extrema?

No. Video validation serves all of Brazil. In-person service in Extrema, MG, is there for those who prefer it, for those who only have a digital ID, and for cases where the rules require being present.

Which should I choose: A1, A3 or Cloud?

If you issue invoices from software installed on a single computer, A1 does the job and costs less. If you sign from your phone, travel or use more than one computer, Cloud saves you headaches. An A3 token makes sense when some system requires physical media.
