Chairman Tom Wheeler 
Federal Communications Commission 
445 12th Street SW 
Washington, DC 20554 
Chairman Wheeler: 
August 7, 2014 
It is our understanding that the Federal Communications Commission will soon select 
the Administrator for the Local Number Portability Administration. We are writing to urge you 
to carefully consider the security implications of the Commission's selection. 
The Local Number Portability database is generally used when a customer switches 
carriers, but elects to retain their phone number. The information in the database is frequently 
updated and pushed out to more than 2,000 carriers across our country. Additionally, a 
separate service is used by the FBI and other law enforcement agencies during the initiation of 
an authorized investigation to determine which carrier is associated with a specific telephone 
number. 
We are concerned that the bidding and selection process will not adequately address 
the inherent national security issues involved in this database. We urge you to consult with 
federal agencies charged with protecting our national security, including the FBI, DHS, and DOD 
to determine how best to protect this infrastructure from both outsider and insider 
threats. We also recommend that you to incorporate security requirements into the RFP and 
award process for the contract. 
This letter is not intended to promote or advocate for any particular vendor, and we 
have no position on which vendor the Commission ultimately selects. Rather, we seek to 
ensure security considerations are adequately prioritized in any decision-making involving 
critical infrastructure. 
Sincerely, 
Mike J. Rogers 
Member of Congress
