# First access to Brazil's Emissor Nacional for ME and EPP companies

By Rotomal team · Updated 2026-11-03 · Part of [Emissor Nacional Pronto](https://rotomal.com/en/nfse-nacional/)

**Short answer:** In the Emissor Nacional, gov.br login works only for MEI. ME and EPP companies, even in the Simples Nacional, log in one of two ways: a username and password created under first access, which checks the legal representative's details such as voter ID or income tax receipts, or an e-CNPJ or e-CPF digital certificate. The official FAQ of 27 October 2026 says access also depends on the city authorising the CNPJ in the Complementary National Register (CNC); the guidance of 29 October 2026 says that for periods from 1 November 2026 all Simples companies are enabled, whether or not they are in the city register. If access still fails over registration, the fix is with the city.

## The three ways to log in

| Method | Who can use it | Note |
| --- | --- | --- |
| gov.br account (silver or gold) | MEI only | For ME and EPP the system says issuing is allowed only for MEI companies |
| Username and password | ME, EPP and other companies | Created under first access; the CPF must be the CNPJ's legal representative |
| Digital certificate | Any company | e-CNPJ, or e-CPF, including a proxy's |

## First access step by step

- In the Emissor Nacional, choose first access (Fazer primeiro acesso) and enter the CNPJ and the legal representative's CPF.
- Pass the identity check: voter ID or the representative's last two income tax receipts.
- Create the password and log in with username and password.
- Check and complete the company data, an address with a valid CEP and the Simples regime.
- Set up the services you provide before issuing the first invoice.

## Common errors and what they mean

| Message or code | Usual cause | What to do |
| --- | --- | --- |
| Não foi possível criar seu usuário | CNPJ not authorised in the city register or data differs from the Receita's | Check the data with your accountant and your status with the city |
| E0037 | City has no formal agreement with the national standard | Contact the city; it does not depend on you |
| E0039 | City has not yet enabled the national issuers or finished its configuration | Contact the city |
| E0010 | DPS series outside the range for the channel used (web, app or API) | Use the series range for that channel |
| E0316 | NBS code not in the national table (version 2.0) | Use the NBS 2.0 code |
| E0240 | Invalid CEP in the register | Correct the company's or customer's CEP |

Codes and explanations from the official FAQ, version 1.2 of 27 October 2026.

## When a digital certificate is worth it

For the web issuer, the official FAQ lists username and password as an alternative to a certificate for ME and EPP. The provider's own ICP-Brasil certificate is mandatory if your ERP or paid issuer sends invoices through the API, and it helps if a proxy will issue for you.

For accountants, since 1 November the portal supports representation and profile switching, without sharing your password.

## FAQ

### I was MEI and became ME. Does my gov.br login still work?

Not for issuing as an ME. Do the first access with username and password or use a digital certificate.

### Can my accountant issue for me?

Yes. They can use a proxy's digital certificate or the portal's new representation and profile-switching feature.

### Is the city service code still needed?

The 6-digit national tax code is the main one. The 9-digit city code is optional, and if it is rejected you can send only the national code.

### How long does setup take?

With the details at hand and the city enabled, it usually fits in one call of about 45 minutes, including the first invoice.
