Does my certificate have an expiration date? Will I lose it?

Yes, it has a validity period, like a document that expires. A certificate isn't forever. When the date arrives, it stops working, and that can block your invoice issuance at the wrong time, like month-end. That's why TF Con tracks the expiration of your e-CNPJ and gives you a heads-up in advance so you can renew without a rush. The exact term varies depending on the type you contracted (A1 or A3), and the rules changed in 2026, so confirm the current validity with your accountant at TF Con.
