When is a carta certificada enough?
When what you must show is that you gave notice in time: cancelling insurance, giving notice on a flat or telling the community of owners your address. In those cases the law asks for written notice or a method that proves receipt, and a carta certificada meets it.
Use a burofax with certified content when the other side could deny what the letter said and that decides the outcome, for example a demand for unpaid rent before an eviction. Correos sells it at its offices and online.

How do they differ?
| Carta certificada | Burofax with certification | |

| Proves delivery and the date | Yes, with the recipient's signature | Yes, with a receipt if you add one |
| Proves the text of the letter | No | Yes, Correos keeps a certified copy |
| How you send it | Upload the PDF from any country | At a Correos office or on its website |
| Typical use | Notices and cancellations with a deadline | Demands that may end up in court |
In Spain we hand the letter to Correos within 2 working days. Correos takes 2 to 4 business days.
