Identification Numbers

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

Registrant ID

Client ID

(9 digits)

12345

(First 5)

6789

(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 House ID: 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.

Senate ID Numbers

Your Senate ID number is made up of two numbers separated by a hyphen. The number before the hyphen is called your User ID/Registrant ID and is the same for all of your clients. The User ID is followed by a hyphen and your Client ID. Your Client ID is specific to each client.  For example, lobbying registrant K Street Incorporated has three clients: Constitution Group, Independence Group, and Democracy Group. K Street Incorporated’s Senate ID numbers are as follows:

Registrant Name

Client Name

User/

Registrant ID

Client ID

Complete Senate ID

K Street Incorporated

Constitution Group

12345

12

12345-12

K Street Incorporated

Independence Group

12345

24

12345-24

K Street Incorporated

Democracy Group

12345

36

12345-36

If you are filing a registration for a new client, you will use only your User ID/Registrant ID as your Senate ID number on the LD-1 form. You will be assigned a new Client ID after you submit the new client’s registration.

If you are filing a registration amendment or lobbying report, you will need to use your complete Senate ID, composed of the User ID/Registrant ID, hyphen, and Client ID.
