Marketing in Argentina: the data protection law, the No Llame registry and how to hire a digital marketing agency

Marketing in Argentina is mobile-first, Spanish-language and Google-led, under three laws a foreign company has to know: personal data needs free, express and informed consent under Law 25,326, telemarketing must respect the national No Llame registry under Law 26,951, and the details in your ads become part of the contract with the consumer under Law 24,240. Write in Argentine Spanish, keep every Google, Meta and analytics account in your own company's name, and check how an agency handles these rules before you compare proposals.

The Argentine market in numbers

StatCounter's figures for September 2026 put Google at 93.82% of searches in Argentina, Bing at 4.71% and Yahoo at 1.06%. So search work means Google, measured in Google Search Console.

On social media, StatCounter's referral figures for the same month show Facebook sending 78.58% of the social visits to websites in Argentina, YouTube 12.38%, Instagram 6.07%, X (Twitter) 1.35% and LinkedIn 0.68%. YouTube sends about one social visit in eight, so video is worth planning for, not only posts.

Law 25,326 and your data

Argentina's personal data protection law sets the base rules for forms, lists and targeting:

• Consent. Article 5 makes processing personal data unlawful where the person has not given free, express and informed consent, recorded in writing or by an equivalent means suited to the circumstances. Where consent is given together with other statements, it must appear expressly and prominently.
• Marketing databases. Article 27 allows data suitable for building promotional, commercial or advertising profiles, or for working out consumer habits, to be processed for direct marketing when it comes from documents open to the public, was provided by the people themselves, or was obtained with their consent.
• The right to be removed. Under the same article, the person can access their data free of charge and ask at any time to have their name withdrawn or blocked from such databases.

For an agency, that means every lead form records consent clearly and separately, every list has a known source, and every email or message gives an easy way to be removed.

The No Llame registry

Law 26,951 created the national No Llame registry, which applies across the whole country. The Ministry of Justice's plain-language guide explains that it protects people from unrequested calls and messages offering services or advertising, that registration is free, and that it protects whoever uses the line, fixed or mobile, even if they are not the account holder. Once a number is registered, advertisers have up to 30 days to stop calling it, and the protection covers all kinds of calls, even when what is offered is free. Complaints are made through the registry's website. If your agency runs calls or message campaigns, ask how it checks numbers against the registry before each campaign.

Advertising claims and CONARP

Article 8 of the consumer protection law, Law 24,240, says the details stated in advertising, notices, leaflets or other media are treated as part of the contract with the consumer and bind the seller. Where goods or services are offered for purchase by phone, catalogue or mail, the seller's name, address and CUIT tax number must appear. So the price, conditions and features in a campaign must be ones you can honour.

The advertising industry also runs its own self-regulation body, the Consejo de Autorregulacion Publicitaria (CONARP) in Buenos Aires. Its members include the associations of Argentine agencies, media agencies, advertisers and interactive agencies, and it publishes a code and the cases it has decided. Asking whether an agency is part of one of those member associations is a reasonable first check.

Agencies price by monthly retainer, fixed project or hours. Agree the currency of the quote and how any price adjustment works in writing, and compare proposals on named people, deliverables, reports and exclusions. For SEO, refuse any offer that promises a position: Google's own guidance says "No one can guarantee a #1 ranking on Google." If your team reads Spanish, our Spanish guide to what an SEO agency does and what to get in writing before you hire one goes through the contract.

Buenos Aires and the rest of the country

For a local business in Buenos Aires, search is by neighbourhood, from Palermo to Belgrano to the city centre. Own your Google Business Profile, use the real address and opening hours, add photos, and if you list a WhatsApp number, answer it quickly. A company serving Cordoba, Rosario or Mendoza as well should build a real page for each city it serves, not a Buenos Aires page with the name swapped. Our Spanish guide to local SEO and how Google decides which businesses to show on the map lists what you can fix yourself.

Questions about marketing in Argentina

Can we use a bought email list in Argentina?

Only if the data came from public documents, from the people themselves, or with their consent, as article 27 of Law 25,326 requires, and every person can ask at any time to be removed.

Does the No Llame registry cover text messages?

The Ministry of Justice's guide describes it as protection against unrequested calls and messages offering services or advertising, on fixed and mobile lines.

Do the prices in our ads bind us?

Yes. Article 8 of Law 24,240 treats the details in advertising as part of the contract with the consumer.

Should we write in neutral Spanish or Argentine Spanish?

If Argentina is the main market, write for Argentine readers. Neutral Spanish can work across countries, but local copy reads more naturally to local buyers.

When can we judge whether our agency is delivering?

Read Search Console for impressions and positions, the ad accounts for cost per enquiry, the Business Profile performance report for calls and messages, and your own count of enquiries by source. The outcome depends on competition, your offer and your budget.

What an Argentine buyer hears from ChatGPT

Gemini has a bigger share in Argentina than in most of Europe: StatCounter's September 2026 chatbot figures give ChatGPT 74.63% of use and Gemini 19.10%. When a marketing manager in Buenos Aires asks one of them for the best digital marketing agency in Argentina, it answers with a few names drawn from Spanish-language directories, Argentine business press, award lists and agency sites. That list is chosen differently from Google's results. AI Knows Us checks it for a business, asking its buyers' real questions on ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews and showing which firms are named and which sources each answer relies on.
