Buying from informal sellers or on social media in Peru: what protection do you actually have?

The real problem: the law protects “consumers,” but only against a “proveedor”

Law 29571, Peru’s Consumer Protection Code, doesn’t protect just anyone buying something from anyone else. It protects the consumer against a proveedor (provider), and the law’s Preliminary Title (Article IV) defines a proveedor as someone who acts habitually: manufacturing, distributing, importing, or selling products or services as part of a regular economic activity.

That means the law, by design, wasn’t built to regulate one-off sales between private individuals. If your neighbor sells you their used bicycle a single time, that neighbor is not a “proveedor” under Law 29571 — even though money changed hands and the deal went badly. The question that decides everything, then, isn’t “did I have a bad buying experience?” but “does the person who sold to me act habitually as a business, even an informal one?”

Does a Facebook Marketplace or Instagram seller count as a “proveedor”?

This is where things get genuinely gray, and any flat answer (“always yes” or “never”) would be dishonest. Habitualness is assessed case by case, looking at signals like:

• Frequency: Do they post and sell constantly, or was this an isolated listing?
• Volume and catalog: Do they have several products permanently on offer, like a store, or did they sell a single used item?
• Commercial presence: Do they have a page with a business name, logo, customer service, set hours? Or is it a personal profile that posted “selling this” once?
• Whether it’s their income source: Someone who makes a living reselling clothes on Instagram — even without a RUC — looks a lot more like a “habitual proveedor” than someone who sold their old laptop.

A seller with an active catalog, constant listings, and high sales volume likely does qualify as a habitual proveedor, even if they’ve never registered for a RUC or issued a receipt — tax informality (no RUC) is a different problem from commercial habitualness (selling constantly), and it’s the latter that triggers Law 29571. On the other hand, someone who sold a single used piece of furniture once in a neighborhood WhatsApp group most likely falls outside Indecopi’s scope, however badly the transaction went.

What if Indecopi has no jurisdiction?

If the seller is genuinely occasional (not habitual), Indecopi can dismiss your complaint for lack of jurisdiction. That doesn’t mean you’re left with zero legal options — it means your remedy shifts away from an administrative agency and into civil or criminal territory, depending on what went wrong:

• If the product simply never arrived, is defective, or doesn’t match what was agreed, but there was no deliberate deception: the route is a civil lawsuit for breach of contract, generally at the Juzgado de Paz Letrado (small-claims-level court) for smaller amounts, through the summary process. It’s slower and more formal than an Indecopi complaint, and you’ll likely need legal advice or support from a free legal-aid clinic.
• If there was deliberate deception from the start (the seller never had the product, disappeared after getting paid, used a fake identity, or knowingly sold a counterfeit while passing it off as genuine): this can constitute the crime of estafa (fraud), under Article 196 of the Criminal Code, which punishes obtaining an unlawful benefit through deception with one to six years of imprisonment. This criminal route is independent of whether the seller qualifies as a “habitual proveedor” — fraud doesn’t distinguish between a formal and an informal seller; it distinguishes between deliberate deception and its absence.

Key distinction: breach of contract vs. fraud

It’s easy to blur these two scenarios, but the difference matters a lot for deciding where to go:

• Breach / poor quality: the seller exists, is identifiable, responded to your messages, but the product arrived damaged, isn’t what was promised, or took longer than agreed. Here the natural path is Indecopi (if they’re a habitual proveedor) or the Juzgado de Paz Letrado (if not).
• Fraud: the seller never intended to deliver, took your money and disappeared, blocked your number, or used a fake account from the start. Here the path is a criminal complaint (police station or Fiscalía), not a consumer complaint, because the problem isn’t “poor service quality” — it’s a crime.

Many real cases mix both elements, and it isn’t always obvious upfront which category applies. If you’re unsure, filing a fraud complaint doesn’t close the door on also pursuing a civil claim later, and vice versa.

Practical tips when buying on social media or from street vendors

1. Before paying, check the account’s or page’s history: old posts, reviews from other buyers, how long the account has existed.
2. Avoid paying 100% upfront to unknown sellers for higher-value items when possible; try to negotiate payment on delivery or a partial deposit instead.
3. Save screenshots of the entire conversation from the first message, including photos of the offered product and any promises about timelines or guarantees.
4. Keep the proof of payment (Yape, Plin, bank transfer) showing date, amount, and recipient details — this is often key to identifying the seller if something goes wrong.
5. If you bought a counterfeit, note that selling counterfeit goods can also have consequences for the seller under intellectual-property rules, independent of your individual consumer complaint.

What this guide can’t promise you

Law 29571 doesn’t contain a closed checklist of “how many sales per month makes someone a habitual proveedor.” That evaluation is made by Indecopi case by case, and it’s entirely plausible for two complaints with similar facts to reach different outcomes depending on how the evidence of habitualness is presented. If your case involves a significant amount or a hard-to-identify seller, a specific consultation with a lawyer before committing time to the wrong path is worth it.
