Pursuant to Rule 461 under the Securities Act of 1933, as amended, TransUnion (the “Company”) hereby requests that the effective date of the above-referenced Registration Statement be accelerated so that it may become effective at 4:00 p.m., Washington, D.C. time, on June 24, 2015, or as soon as possible thereafter.
