What is certified SMS<\/strong><\/h2>\n\n\n\n

A Legalpin certified SMS<\/a><\/strong> is a text message sent to the recipient’s mobile phone that includes verifiable record of sender, destination, date, time, and content, and has full legal validity<\/strong>.<\/p>\n\n\n\n

This means allows proving not only that the message was sent, but that it effectively reached the indicated number and a digital receipt with timestamp<\/strong> was generated that can be used as evidence before third parties.<\/p>\n\n\n\n

Thanks to its simplicity, speed, and economy, certified SMS<\/strong> presents itself as a modern and efficient alternative for communications that require legal security and traceability<\/strong>.<\/p>\n\n\n\n

What is burofax<\/strong><\/h2>\n\n\n\n

The term postal burofax<\/a><\/strong> refers to an urgent document or communication delivery service that allows proving message content, sender, recipient, date, and time, and has evidentiary value<\/strong> before courts.<\/p>\n\n\n\n

Although historically associated with physical postal environments, currently digital versions also exist (electronic burofax<\/strong>, certified email<\/strong>, certified SMS<\/strong>) that offer equivalent legal validity<\/strong> through qualified trust-service providers under eIDAS<\/a>.<\/p>\n\n\n\n

It’s mainly used in formal notifications, legal requirements, non-payment claims, or to leave record of facts with legal relevance, thanks to its ability to ensure a “certain date” of the communication.<\/p>\n\n\n\n\n

Electronic burofax vs certified SMS: long-tail use cases<\/strong><\/h2>\n\n\n\n

Electronic burofax<\/strong> (email\/SMS with access link and acceptance signature) works well when the recipient must read a full PDF and acknowledge receipt. Certified SMS<\/strong> is better for short, urgent, legally relevant messages: labour warnings, contract cancellations, payment demands, or condition changes where speed matters.<\/p>\n\n\n\n
