SMS Compliance in Chile
A practical overview of the rules that affect SMS messaging and marketing in Chile, with a checklist before you launch.
Key Rules for SMS in Chile
Chile's Consumer Protection Law (Law 19.496) requires promotional messages to identify the sender and show how to stop receiving them, and consumers can register on SERNAC's 'No Molestar' list to block marketing calls and messages.
In North America, business texting is shaped by carrier rules as well as law: in the US, application-to-person messaging on standard numbers generally requires brand and campaign registration (10DLC), and the TCPA requires appropriate consent. Other countries in the Americas have their own consumer protection and data laws.
Data Protection
Personal data is governed by Law 19.628, and the new Personal Data Protection Law 21.719, with a dedicated data protection agency, takes effect in December 2026.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Collect and record consent (or confirm an existing customer relationship) before sending, with the date and source.
- Use a registered sender ID or number that recipients can recognise as your business.
- Identify your business in every message and keep promotional and service messages separate.
- Give a simple way to opt out of marketing and process opt-outs quickly across all your systems.
- Send in the recipient's local daytime hours and keep frequency reasonable.
Contact data
Format numbers in international E.164 format with the +56 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Chile follows the America/Santiago time zone (UTC-03:00 in October 2026). The usual working week is Monday to Friday. Schedule SMS campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Santiago, customers commonly use Spanish. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Chile
Chile has high internet and smartphone use, and WhatsApp is the main messaging app, with Instagram driving discovery. Chile's new personal data protection law (Law 21.719) was enacted in 2024 and creates a data protection agency, with obligations phasing in by December 2026.
Cards, bank transfers and WebPay are the main online payment methods. CyberDay, Black Friday, Fiestas Patrias in September and Christmas are key periods.
Chile is the world's largest copper producer, and mining, lithium from the Atacama salt flats, salmon farming, wine and fresh fruit exports drive the economy, with Santiago concentrating most corporate headquarters, banks and retailers such as Falabella and Cencosud. VAT (IVA) is 19%. Consumers can sign up to SERNAC's 'No Molestar' register to block advertising calls, SMS, WhatsApp and email from specific companies, so suppression lists must be honoured promptly. The main mobile operators are Entel, Movistar, Claro and WOM.
Regulators, Registers and Practical Rules in Chile
Chile's new data protection law, Law 21.719, creates a Personal Data Protection Agency and takes full effect in December 2026. SUBTEL regulates telecoms. Entel, Movistar, Claro and WOM are the operators.
Under the Consumer Protection Law, promotional messages must state how to unsubscribe, and once a person asks to stop, further messages are prohibited. SERNAC runs the No Molestar register, which companies must respect for calls and messages. The CyberDay and Black Friday campaigns produce large spikes in e-commerce traffic, and sender reputation matters during these weeks.
WhatsApp is the main business channel.
