               Re: Registration Statement On Form S-3 Related to Equifax Inc.
                   Common Stock

     Ladies and Gentlemen:

     We have acted as counsel to Equifax Inc., a Georgia corporation
("Equifax"), in connection with the preparation and filing of a Registration
Statement on Form S-3 filed with the Securities and Exchange Commission on
February 1, 2001 (the "Registration Statement") relating to the registration of
an aggregate of 340,545 shares of Equifax'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 such corporate records, other
documents, certificates and other instruments and we have reviewed such matters
of law as we have deemed necessary or appropriate to enable us to render the
opinions expressed below. In rendering the opinions expressed below, we have
assumed (i) the authenticity and conformity to the original documents of all
documents submitted to us as certified, conformed, facsimile or photographic
copies, and the genuineness of all signatures on all documents and (ii) the
correctness and completeness of all documents and certificates of all public
officials.

     Based upon the foregoing, we are of the opinion that the Shares have been
legally issued and are fully paid and non-assessable under the laws of the State
of Georgia as in effect on this date.

     We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"Legal Opinions" in the prospectus contained within the Registration Statement.


                                                Very truly yours,

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