Blocked Mercado Livre account: how to resolve it

Why Mercado Livre blocks accounts

Most account blocks on Mercado Livre happen for four main reasons. Below, we break down each one:

Violations of rules and Terms of Use

The platform primarily blocks sellers who violate its rules. Mercado Livre strictly enforces sales policies and actively monitors attempts to manipulate ratings or reviews. Creating multiple accounts, for example, to bypass an existing block, is also prohibited. Even if a violation seems minor, Mercado Livre treats it as a risk to its entire ecosystem.

Security issues and suspected fraud

Mercado Livre’s algorithms track not only direct violations but also unusual account behavior. A sudden spike in sales, irregular transactions, or frequent logins from IP addresses in different countries can trigger an automated review and a temporary account block. The system collects digital fingerprints and evaluates user behavior to identify potential risks, even when no clear violation is visible.

Selling prohibited products

If a seller lists products that are banned by Mercado Livre, the account is almost guaranteed to face sanctions. Prohibited categories include weapons, tobacco products, medications, event tickets, and others. Depending on the violation severity, Mercado Livre may block the account temporarily or permanently.

Registration data issues and high complaint rates

If profile data does not match official records — such as CPF* or CNPJ** numbers, bank details, or address information — Mercado Livre may temporarily block the account for verification.

Users must provide accurate and up-to-date information when registering on Mercado Livre. Any discrepancies are treated as potential threats, especially if complaint rates, returns, or order cancellations are also increasing.

*CPF (Cadastro de Pessoas Físicas) is an individual tax identification number in Brazil.

**CNPJ (Cadastro Nacional da Pessoa Jurídica) is a company tax number that confirms legal business status.

How to restore a blocked Mercado Livre account

After an account block on Mercado Livre, it is important to act calmly and systematically.

Identify the reason for the block

The first and most critical step is to understand why the account was blocked. Mercado Livre usually sends a notification explaining the reason. If the explanation is unclear, request clarification through the Mercado Livre help center. Knowing the exact cause of the block allows you to prepare a strong appeal and gather the right evidence. Without this step, the chances of success are low.

Gather supporting documents

To increase your chances of account recovery, prepare the following in advance:

• Passport or relevant business registration documents;

• Proof of address (a lease agreement for individuals or legal documents for companies);

• Bank details;

• Product documentation.

A complete and well-organized document package shows the platform that you take compliance seriously and are ready to fix the issue.

Submit your appeal

An appeal should be clear, logical, and free of emotion. In your message:

• Briefly describe the situation and the reason for the block;

• Explain what actions you took to correct the issue;

• Attach supporting documents.

The more precise the information, the higher the chance of a positive decision. Responses usually arrive within a few business days.

Monitor the process

After submitting the appeal, track its status closely. If support requests additional information, send it without delay. Slow responses can extend the review or lead to rejection. Regular follow-ups show the platform that you are cooperative and committed to resolving the issue.

What to do if your appeal is rejected

If your appeal is rejected:

• Check whether your Mercado Livre account is linked to another blocked account. If it is, restore the older account first.

• Submit a follow-up request with additional supporting evidence.

• Consult a lawyer experienced in e‑commerce in Brazil.

• File a complaint on the online platform Reclame Aqui.

How to avoid account blocks in the future

Restoring an account is only one part of the process. To prevent future account blocks on Mercado Livre, you need a systematic approach. Mercado Livre evaluates not only rule compliance but also customer service quality, data accuracy, and account behavior.

Build and protect your reputation

The platform tracks key metrics: return rates, order cancellations, buyer complaints, and processing speeds. If performance declines, the system may first limit account features and later apply a full account block. Regular audits — reviewing feedback, improving logistics, and refining product descriptions — help reduce risks and demonstrate that issues are always properly addressed.

Keep information up to date

Beyond account behavior, registration data must always remain accurate. Any mismatch in CPF numbers, CNPJ details, bank information, addresses, or contact data may be flagged as a risk by Mercado Livre.

Handle multiple accounts carefully

Mercado Livre is cautious about multiple accounts. According to its rules, each account should be personal and unique. If the platform detects several accounts linked to one user and considers this a community risk, it may block all of them.

In practice, situations may vary. A seller may have a personal account and a separate business account, or multiple businesses with different legal entities. When you log into several Mercado Livre accounts using a common browser, the system can link them using device fingerprinting.

In such cases, technical account isolation is essential. It reduces the risk of accounts being connected by fingerprint data and makes multiple account management from one device much easier. Solutions like Octo Browser are designed specifically for this purpose: Octo Browser creates isolated profiles, each with its own fingerprint. You can also connect residential proxies to your Octo profiles, so your Mercado Livre accounts do not share the same IP address. With fingerprints and IPs separated, each account appears to Mercado Livre as a distinct user.

Conclusion

A Mercado Livre account block can seriously disrupt sales and business operations. In most cases, suspensions result from rule violations, suspicious activity, registration data issues, or selling prohibited products.

To restore a Mercado Livre account, it is crucial to identify the exact reason for the block, prepare supporting documents, and submit a clear appeal. After that, monitor the process and respond quickly to any requests from support.

Careful account management and consistent compliance help minimize the risk of future blocks and protect stable sales on Mercado Livre. For safer operations, separating personal and business accounts with solutions like Octo Browser can significantly reduce technical risks.

Frequently asked questions

Why was my Mercado Livre account blocked?

The most common reasons include rule violations, suspected fraud, selling prohibited products, incorrect registration data, or a high volume of buyer complaints. If you work with multiple accounts — such as a personal account and one or more business accounts — it is important to avoid account overlap. This significantly lowers the risk of account blocks because Mercado Livre cannot link accounts through a shared device fingerprint. Anti-detect browsers like Octo Browser create virtual profiles, each with a separate unique fingerprint, making logins appear as if they come from different physical devices.

Can a blocked account be restored?

Yes. You need to determine the exact reason for the block, collect supporting documents, and submit an appeal through the support center. After you submit the appeal, monitor the process and provide additional information if requested.

Can I create a new account if my old one is blocked?

We do not recommend creating a replacement account, as this violates Mercado Livre rules. However, users may open a different account type, such as a personal or additional business account. In such cases, it is critical to reduce the risk of another account block and avoid links between accounts. This can be done by using anti-detect browsers that create isolated profiles with unique fingerprints and can connect dedicated proxies to each profile.
