House ID Numbers

When a new lobbying firm, or individual, registers with the House, a unique ID is created for that registrant.  Each time a new client is registered for that registrant, a sequential 4 digit number is created and combined with the registrant ID to create the House ID for that client, as shown in the example below:

Complete House ID Number:

12345

6789

(9 digits)

Registrant ID

(First 5)

Client ID

(Last 4)

For example, lobbying registrant K Street Incorporated has three clients:  Constitution Group, Independence Group, and Democracy Group.  K Street Incorporated’s House ID numbers are as follows:

Registrant Name:  K Street Incorporated

12345

Client Name:

House ID:

Constitution Group

123450000

Independence Group

123450001

Democracy Group

123450002

Notice that the first 5 digits in this example remain the same, since all three clients are registered for the same lobbying firm.  When you register a new client, you will use the first 5 digits, which is the registrant portion of your House ID.  When you file a lobbying activity report, you will use the full 9 digit House ID for each client.
