 CERTIFICATION PURSUANT TO
RULE 13A 14 OF THE SECURITIES EXCHANGE ACT OF 1934,
AS ADOPTED PURSUANT TO
SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002
  1.
    
    I have reviewed this Annual Report on Form 10-K of MercadoLibre, Inc. (the registrant);2.
    
    Based on my knowledge, this report does not contain any untrue statement of a material
fact or omit to state a material fact necessary to make the statements made, in light of
the circumstances under which such statements were made, not misleading with respect to
the period covered by this report;3.
    
    Based on my knowledge, the financial statements, and other financial information
included in this report, fairly present in all material respects the financial
condition, results of operations and cash flows of the registrant as of, and for, the
periods presented in this report;4.
    
    The registrants other certifying officers and I are responsible for establishing and
maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a
15(e) and 15d 15(e)) and internal control over financial reporting (as defined in
Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
 (a)
    
    Designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be
designed under our supervision, to ensure that material
information relating to the registrant, including its
consolidated subsidiaries, is made known to us by others
within those entities, particularly during the period in
which this report is being prepared;(b)
    
    Designed such internal control over financial reporting,
or caused such internal control over financial reporting
to be designed under our supervision, to provide
reasonable assurance regarding the reliability of
financial reporting and the preparation of financial
statements for external purposes in accordance with
generally accepted accounting principles;(c)
    
    Evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in this report our
conclusions about the effectiveness of the disclosure
controls and procedures, as of the end of the period
covered by this report based on such evaluation; and(d)
    
    Disclosed in this report any change in the registrants
internal control over financial reporting that occurred
during the registrants most recent fiscal quarter (the
registrants fourth fiscal quarter in the case of an
annual report) that has materially affected, or is
reasonably likely to materially affect, the registrants
internal control over financial reporting; and
 5.
    
    The registrants other certifying officers and I have disclosed, based
on our most recent evaluation of internal control over financial
reporting, to the registrants auditors and the audit committee of
registrants board of directors (or persons performing the equivalent
function):
 (a)
    
    All significant deficiencies and material
weaknesses in the design or operation of internal
control over financial reporting which are
reasonably likely to adversely affect the
registrants ability to record, process,
summarize and report financial information; and(b)
    
    Any fraud, whether or not material, that involves
management or other employees who have a
significant role in the registrants internal
control over financial reporting.
