  Re:  Equifax Inc.
       Registration Statement on Form S-3
       ----------------------------------

Ladies and Gentlemen:

  We have acted as counsel for Equifax Inc., a Georgia corporation (the
"Company"), in connection with the registration under the Securities Act of
1933, as amended, pursuant to a Registration Statement on Form S-3 to be filed
by the Company with the Securities and Exchange Commission (the "Registration
Statement"), of an aggregate of 266,374 shares of the Company's Common Stock, $
1.25 par value per share, to be sold by certain Selling Shareholders named in
the Registration Statement (the "Shares").

  In rendering this opinion, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents, corporate records,
certificates of officers of the Company and certificates of public officials as
we have deemed appropriate for the purposes of providing this opinion.

  In our examination, we assumed the genuineness of all signatures, the legal
capacity of all natural persons, the authenticity of all documents submitted to
us as originals and the conformity to original documents of all documents
submitted to us as certified or photostatic copies.

  Based upon the foregoing, and in reliance thereon, and subject to the
limitations, qualifications and exceptions set forth herein, we are of the
opinion that the Shares have been duly authorized and are validly issued, fully
paid and non-assessable under the laws of the State of Georgia as in effect on
this date.

  We hereby consent to the reference to our Firm under the heading "legal
opinion" in the Prospectus contained in the Registration Statement and to the
filing of this Opinion with the Securities and Exchange Commission as an exhibit
to the Registration Statement.

                                          Very truly yours,


                                         /s/ Hunton & Williams
                                         -----------------------------------
