| Update: | SEFAZ Paraná updates CSRT validation requirement for NF-e and NFC-e |
| Date: | 202-09-11 |
SEFAZ PR has announced updates about the CSRT (Security Code of the Technical Responsible) requirement in Paraná state.
Starting April 2025, businesses issuing Electronic Invoices (NF-e) and Electronic Consumer Invoices (NFC-e) will need to validate the CSRT identifier (idCSRT) and CSRT Hash (hashCSRT), in line with NPF No. 063/2012 and Technical Note 2018.005.
The CSRT is a security code only known to the Paraná State Revenue and the software supplier. It will be used to generate a "hash" with the access key, linking the NF-e XML generation to the supplier's system.
