Messaging Compliance in Argentina

Overview

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.

Law 25.326 requires a lawful basis and notice for personal data use, and the AAIP supervises compliance.

Spanish is the search language, and Rioplatense Spanish uses voseo ('vos' instead of 'tú'), which local copy should reflect.

WhatsApp is a major business channel in much of Latin America, while in the US and Canada it is used alongside SMS. Consent and data protection laws in each country apply to WhatsApp marketing.

Automated and prerecorded calls are tightly regulated in the US (TCPA and the National Do Not Call Registry) and Canada (CRTC Unsolicited Telecommunications Rules), and other countries in the region have their own registers and rules.

Advertising Rules

Advertising must follow the Consumer Protection Law 24.240 and the fair trade rules, with clear and truthful offers and conditions.

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.
