How to generate a DANFE using an access key

In the dynamic world of Brazilian logistics and accounting, losing a physical document is a common setback, but one that can cause major headaches. If you've ever found yourself needing a tax document and only having that endless sequence of numbers on hand, this guide is for you. The access key for the Electronic Invoice (NF-e) is the master code that unlocks data recovery and the issuance of the Auxiliary Document of the Electronic Invoice (DANFE).

In this article, we'll delve into the technical and practical details of how to transform those 44 digits into a document ready for printing or digital sending. Whether it's for releasing a truck at a tax checkpoint or organizing the entry of goods into your inventory, mastering the art of generating the document using the key is an essential skill for any modern professional.

The anatomy of the access key and its usefulness.

Before we move on to the practical part, it's essential to understand what these 44 numbers that make up the access key are. It's not a random sequence; each block of numbers carries vital information about the operation. The first two digits indicate the state code (UF) of the issuer; the next four show the year and month of issuance; then we have the 14 digits of the issuing company's CNPJ (Brazilian corporate tax ID).

The sequence continues with the invoice model (usually 55), the series, the invoice number, and the type of issuance. The last digits make up the invoice's own numerical code and a check digit. Having this key means possessing the unique identity of that transaction in the national database. Therefore, when consult DanfeBy doing so, you are directly accessing the source of fiscal truth, ensuring that the generated document is authentic and up-to-date with the SEFAZ (State Finance Secretariat) status.

The technical process behind online generation.

Many users wonder how a website can "generate" a document from just a number. The process is a technological integration: when you enter the key into a generator, the system sends a request to the State Treasury Department's servers. If the invoice is authorized, the basic data is returned, allowing the platform to fill in a standardized DANFE layout.

This agility is what allows companies to maintain workflow even when the original XML file has been lost or has not yet been processed by the finance department. Key-based generation is a contingency and agility solution, transforming what would be a bureaucratic problem into a procedure that takes seconds.

FAQ

How do I print the DANFE using the access key?

To print, you must choose one of the online generation platforms mentioned, enter the 44-digit access key in the search field, and request a preview. Once the PDF document is generated on the screen, use the print function of your browser or PDF reader, ensuring that the scale is set to 100% on A4 paper.

Where can I find the access key?

The access key is always printed in the upper right corner of any DANFE you already have. If you don't have the physical document, it can be found in the XML file of the invoice (in the tag). This information can be found in the purchase confirmation emails sent by the supplier. If you are the buyer and have lost everything, the sender is obligated to provide this information.

Is it possible to download the complete XML file using only the key?

Currently, the Brazilian Federal Revenue Service restricts the download of the complete XML file only to those who possess a Digital Certificate (A1 or A3) and are involved in the transaction (such as buyer, seller, or transporter). However, for viewing and printing the DANFE (Documento Auxiliar da Nota Fiscal Eletrônica - Auxiliary Document of the Electronic Invoice) for transport and verification purposes, the access key without a certificate is usually sufficient in most public query tools.

What should I do if the access key is invalid?

If the system returns that the key is invalid, first check if there was a typing error in the 44 digits. If the numbers are correct, the invoice may be very recent (less than 10 minutes) and has not yet been propagated to the national servers, or the invoice may have been issued in a test environment, which has no real fiscal value for the circulation of goods.

How can I check an invoice using my CPF (Brazilian tax identification number)?

Searching by CPF (Brazilian taxpayer ID) is more restricted and generally requires the user to access their state's Finance Department portal using a gov.br system password or digital certificate. Unlike the access key, which is public for summary consultation, searching by CPF falls under the realm of data privacy, requiring authentication to list all invoices issued against that document.
