Requests by filing parties for filing status and transaction numbers should be addressed to the email address or the general PNO number: (202) 326-3100. All HSR questions concerning the rules should be directed to the email address

The Premerger staff receives hundreds of inquiries each week, and thousands every year, asking for interpretations of the HSR statute and rules. Many of the questions can be answered by reference to the statute, rules and information contained on this web site. Given the high volume of inquiries, we recommend that you review these online materials before contacting the PNO. If you still have questions after reviewing these materials, we will be happy to answer questions.

Inquiries should be sent via email to, preferably after the structure of the transaction is as close as possible to being finalized. When emailing, in order to serve you better, please outline facts and references, including the structure of the transaction and all relevant factors, and present your initial conclusions. Your cooperation is appreciated.

Special Notice Concerning Delivery of Filings to the Premerger Notification Office

Please note that security measures in place at the Commission may cause delays in the receipt of filings sent via shipping companies such as FedEx and UPS.  All shipped packages must be processed by the mailroom before delivery to the PNO.
