Ladies and Gentlemen:

We have acted as special Chilean counsel to MercadoLibre Chile Ltda. a limited liability partnership (sociedad de responsabilidad limitada) organized and existing under the laws of the Republic of Chile (the “Guarantor”), a subsidiary of MercadoLibre, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of a registration statement on Form S-3 (Registration Nos. 333-251835, 333-251835-01, 333-251835-02, 333-251835-03, 333-251835-04, 333-251835-05, 333-251835-05, 333-251835-06, 333-251835-07, 333-251835-08, 333-251835-09) (including the documents incorporated by reference therein, but excluding Exhibit 25.1, the “Registration Statement”) filed by the Company and the additional registrants identified therein, including the Guarantor (the “Additional Registrants”) and the prospectus, dated December 30, 2020, as supplemented by the prospectus supplement, dated January 7, 2021 (together, the “Prospectus”) relating to the Company’s offering of $400,000,000 aggregate principal amount of 2.375% Sustainability Notes due 2026 (the “Sustainability Notes”) and $700,000,000 aggregate principal amount of 3.125% Notes due 2031 (the “2031 Notes” and together with the Sustainability Notes, the “Debt Securities”) and the Additional Registrants’ guarantees relating to the Debt Securities (the “Guarantees,” and together with the Notes, the “Securities”).

The Securities were issued pursuant to an indenture dated as of January 14, 2021 (the “Base Indenture”), as amended and supplemented by the first supplemental indenture dated as of January 14, 2021 (the “First Supplemental Indenture,” and together with the Base Indenture, the “Indenture”) entered into among the Company, the Additional Registrants and The Bank of New York Mellon Trust Company, N.A., as trustee, registrar, paying agent and transfer agent (the “Trustee”).

In connection with the opinions expressed herein, we have examined originals or copies certified or otherwise identified to our satisfaction of the following documents:

In addition, we have reviewed and, as to questions of fact, relied to the extent we have deemed appropriate, upon such other documents, instruments and other certificates of public officials, officers and representatives of the Guarantor, except to the extent that such representations cover matters of law as to which we expressly opine herein, and we have made such investigations of law, as we have deemed necessary or appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed without verification: (i) the authenticity of all documents and records submitted to us as originals and the conformity to the originals of all documents and records submitted to us as copies, (ii) the authenticity and genuineness of all signatures on the documents reviewed by us in connection therewith, (iii) the legal capacity of all natural persons, and (iv) the due organization and existence of each of the parties to the Registration Statement, the Indenture and the Securities (except for the Guarantor).

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

We have assumed that the Guarantor has satisfied the legal requirements that are applicable to it under applicable law other than the laws of the Republic of Chile to the extent necessary to make the Indenture, the Debt Securities and the Guarantees, as the case may be, enforceable against it. We have also assumed that each of the Company and the Trustee has satisfied the legal requirements that are applicable to it under applicable law other than the laws of the Republic of Chile to the extent necessary to make the Indenture enforceable against it.

The foregoing opinions are subject to the following qualifications:

This opinion letter is given solely for your benefit in connection with the above-described transaction. This opinion letter may not be used, circulated, quoted or relied upon by you for any other purpose or relied by any other person without our prior written consent; provided that we hereby consent to the use of our name in the Prospectus under the heading “Legal Matters”, as Chilean counsel for the Guarantor that has passed on the validity of its Guarantees under Chilean law, and to the filing of this opinion as Exhibit 5.5 to the Company’s Current Report on Form 8-K dated January 14, 2021. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder. Cleary Gottlieb Steen & Hamilton LLP may rely upon this opinion in rendering their opinion to the Company and the Additional Registrants.
