Soon you'll know instantly if a call is legitimate or a scam attempt. Discover how this system works and get ready to say goodbye to spam.
In the last year, thousands of users in Chile have been victims of calls automated for advertising or fraudulent purposes, which sometimes result in financial losses and security problems.
To put an end to this situation, the Undersecretariat of Telecommunications (Subtel) and the Ministry of Transport and Telecommunications announced an innovative measure, which consists of two exclusive prefixes that will identify the desired and unsolicited communications.
What changed with the new regulations?
Through a regulation published on March 20, 2025, which gave a six-month grace period for adaptation, so, starting this August 13th By 2025, it was established that all companies that carry out mass communications must use one of two number blocks:
• 600: For calls commercials requested or authorized by the user, such as medical appointment confirmations, bank alerts, or previously agreed collection procedures.
• 809: For calls unsolicited, including offers, automated telesales and advertising campaigns without prior consent.
So, when you see a number that starts with 600, you'll know it's a legitimate call linked to a current service or contract. On the other hand, if the number starts with 809, you can decide not to answer, knowing that it's possibly a mass offer or even an attempt at deception.
“Any mass call that arrives without the 600 or 809 will be outside the norm and operators will be able to block it immediately.”
What are its benefits?
• Fewer frauds: By knowing which calls are legitimate, you reduce the risk of vishing and identity theft.
• More transparency: Companies are required to identify themselves correctly.
• Automatic filter: Many phone companies and operators are already fine-tuning their tools to block prefixes other than 600 and 809.
Three tips to take advantage of the change
• Activate call filtering on your cell phone: Most devices come with options to block unknown or unwanted numbers.
• Contact your company: Check with them what identification and blocking services they offer to have double protection.
• Share this information with friends and family: Together we can avoid falling for scams and reduce the annoyance of those persistent calls.
Now you know, from now on, every time your screen displays the correct prefix, you'll know if the caller is someone you trust or if it's better to let the call go straight to voicemail.
With this simple yet powerful measure, Chile takes a firm step to regain control of its telephone lines and minimize the inconveniences and risks associated with spam.
