Digital certificate to issue CT-e, MDF-e and NF-e
Buy your carrier’s ICP-Brasil digital certificate with BrainCargo: special terms, fast issuance, secure validation and the certificate installed on the platform, ready to issue.
To issue CT-e, MDF-e and NF-e, a Brazilian carrier needs an ICP-Brasil digital certificate (ICP-Brasil is Brazil’s national public-key infrastructure) in the company’s name (CNPJ, the company tax ID) — it is what signs every document sent to the tax authority (Sefaz). BrainCargo is a digital-certificate reseller and sells the e-CNPJ A1, the file-based model used for cloud issuing, with special terms for anyone operating on the platform. Identity validation follows every procedure required by ICP-Brasil and is performed by an accredited Registration Authority; once issued, our team helps install the certificate in BrainCargo so you can start issuing without depending on a token, a card or a specific computer.
Anyone setting up the operation tends to stall at the same point: the issuer is ready, but the certificate is missing. With BrainCargo you solve both in one place — buy the A1 digital certificate, validate the legal representative’s identity and leave with the certificate installed in the CT-e issuer, the MDF-e issuer and the NF-e issuer.
The process is fast but skips nothing: certificate issuance follows ICP-Brasil rules, with document checks and validation of the legal representative’s identity. The difference is having someone guiding you through each step, from order to first authorized invoice.
What you can achieve

place to buy and to issue

Frequently asked questions
Do I need a digital certificate to issue CT-e?
Yes. CT-e, MDF-e and NF-e are digitally signed with an ICP-Brasil certificate in the issuing company’s name. Without it, the tax authority does not authorize the document.
Does BrainCargo issue the certificate?
BrainCargo is an ICP-Brasil digital-certificate reseller. We sell it, follow the validation — performed by an accredited Registration Authority, per the rules — and help install the certificate on the platform.
Which certificate do I need: A1 or A3?
For cloud issuing, the recommended one is the e-CNPJ A1: it is a file installed in the issuer, with no token, card or specific computer. That is why BrainCargo works only with A1.
How long does it take?
The process is fast: after the order, we validate the legal representative’s identity and the certificate is issued shortly after. The exact timing depends on the paperwork being in order — our team guides each step over WhatsApp.
Which documents are required?
Those ICP-Brasil requires for the e-CNPJ, such as company data and the legal representative’s ID document. We send the full list at the start of the process.
How much does it cost?
We have special terms for BrainCargo clients. Ask for the price on WhatsApp — if you don’t issue with us yet, we set up the certificate together with the issuing plan.
