SMS Compliance in Argentina
A practical overview of the rules that affect SMS messaging and marketing in Argentina, with a checklist before you launch.
Key Rules for SMS in Argentina
Marketing messages in Argentina must respect the Personal Data Protection Law 25.326 and the national 'No Llame' register created by Law 26.951, which covers calls and messages to phone numbers; the Agency for Access to Public Information (AAIP) enforces both.
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
Law 25.326 requires a lawful basis and notice for personal data use, and the AAIP supervises compliance.
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 +54 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Argentina follows the America/Argentina/Buenos_Aires 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 Buenos Aires, 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 Argentina
Argentina is a WhatsApp-first market, and Instagram is a major discovery and sales channel. The national Do Not Call registry (Registro Nacional No Llame) must be respected for marketing calls.
Mercado Pago is used by a large share of the population, and card instalments (cuotas) are a strong purchase driver; inflation and exchange-rate changes make customers price-sensitive. Hot Sale, CyberMonday, Christmas and the summer holiday season in January and February are key periods.
Argentina's economy is driven by agriculture (soybeans, maize, wheat and beef), energy from the Vaca Muerta shale field, lithium and a large software and services sector, which includes Mercado Libre, Latin America's biggest e-commerce company. Inflation and exchange rate changes mean prices are updated often, so promotions should state clear validity dates. VAT is 21%. Personal Data Protection Law 25.326 applies to marketing lists, and the national 'No Llame' register lets people block telemarketing calls.
Regulators, Registers and Practical Rules in Argentina
Argentina's Access to Public Information Agency enforces Law 25.326, and the Do Not Call register must be checked.
Messages should state the validity of prices and payment terms clearly. Mercado Pago and interest-free instalments are common.
ENACOM regulates telecoms. Personal, Movistar and Claro are the operators.
In practice, many Argentine businesses run sales and support through WhatsApp Business, and customers expect quick replies during business hours. Keep a record of each opt-in and respect the No Llame register for calls and messages to registered numbers.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.
Advertising Alongside Messaging
Advertising must follow the Consumer Protection Law 24.240 and the fair trade rules, with clear and truthful offers and conditions.
