Channels, languages and hours
This is where the conversation happens, from first contact to post-issuance support. The number is +44 7454 581866 and sits behind every button on this site.
Website form
For those who prefer to write at their own pace or do not use WhatsApp. The reply comes by e-mail or through the channel you indicate.
Portuguese and English
The conversation continues in the language you write in. Foreign spouses and non-Brazilian partners are served in English, including during the validation session.
The client's time zone
The base is London, but the schedule adapts to anyone on any continent. Tell us your city and you receive time options on your clock, not ours.
The journey, message by message
Message 1 — your “hello”
You write with your country, the type of certificate (or a question about which) and the purpose. The more specific the purpose, the more precise the reply.
Message 2 — triage
We reply with the recommended model, the fixed price and the document list for your case. If something could block (CPF, document, QSA), we flag it here.
Message 3 — documents
You send a photo of the ID and, for an e-CNPJ, the company's acts. We check the registration status before proposing a time.
Message 4 — booking
We offer two or three windows in your time zone and send the video link with the technical checklist: camera, original document at hand, well-lit room.
Validation session
An agent of our RA checks the document, the person and the CPF live. What happens on screen is described in digital CPF validation abroad.
Message 5 — issuance and installation
Once AC Certisign issues the certificate, we guide the A1 installation or the A3 activation, until you sign your first document or log into e-CAC.
Afterwards
Usage questions continue on the same number. The most common problems are in digital certificate support abroad.
A filmmaker in Vancouver who did it all between two shoots
Real case
Illustrative scenario. A documentary filmmaker in Vancouver needed to sign a licensing contract with a Brazilian broadcaster, which required a signature with an ICP-Brasil certificate, and had a nine-day gap between two shoots. She sent her first “hello” at 10 pm local time, while London slept, and woke up to the triage answered: e-CPF A1, accepted documents, price in writing. She sent a photo of her Brazilian passport, received three morning slots in Pacific time and did the validation at 8 am on a Tuesday. Issuance came through, she installed the certificate on her laptop following the step-by-step and signed the contract in PAdES before flying to the next shoot. Throughout the journey nobody asked for a password, a PIN or the certificate file — because none of them exists outside her computer. — A common profile among creative professionals with contracts in Brazil
What we never ask for — and what we never promise
We never ask for the password
The A1 password and the A3 PIN are set by you and never pass through the RA. No step in the process needs them.
We never ask for the file
The .pfx holds your private key. Sending it to anyone amounts to handing over your signature.
We never promise a guaranteed deadline
Issuance depends on an approved validation and on the CA's systems; we tell you what to expect, not what we do not control.
We never charge a “release fee”
The price agreed in writing is the only one. Any extra charge to “unlock” or “approve” is a scam, not service.
Before you decide
“I am twelve hours away”
The schedule also runs early mornings for Asia and evenings for the Americas. Name your city; you receive windows that work for you.
“My document is about to expire”
If it is valid on the day of the session, it works. If it expires before, we tell you which one to renew and in what order, so no time is wasted.
“How do I know you are a real RA?”
By checking the accreditation with AC Certisign and confirming that the issued certificate appears in the ITI chain. The verification routine is in ICP-Brasil registration authority.
ICP-Brasil registration authority“What if the validation is not approved?”
We explain the reason (illegible document, name mismatch, irregular CPF) and what to correct before a new session.
Transparent pricing
Triage, prior CPF and document checks, the validation session in your time zone, issuance by AC Certisign and guidance up to first use are all within the same price, stated in writing in message 2.
Model and validity set the final figure; A3 devices are itemised separately in the quote.
