All contact information we have for a given individual or company is available on that person's or company's IMDbPro page.
A Person's Contact Information
For example, let's look at Natalie Portman's page. On this page, you'll find her employer and her reps (Talent Agents, Managers, Publicists, Legal reps, etc.) listed in the left column, below her headshot. Her "employers" are listed first as her "Company". Below that you will see a list of all her representatives.
Some of the information may have an orange asterisk " * " next to it. Contact information with the asterisk was added through the IMDbPro Resume claiming that IMDb page. Information added through the IMDbPro Resume cannot be edited or verified by IMDb.
A Company's Contact Information
For example, the United Talent Agency (UTA) page. On this page, you'll find office locations ("Branches"), staff, clients and filmography credits as well as other details.
Branch: Branch locations will be listed in a column on the left.
Staff: You will see a partial list of staff in the middle with a link to view the entire staff roster on its own page. To see the full staff roster, click the "Staff" tab, which will take you to the Staff page. You can sort that page by name, title, STARmeter or branch to more easily find individuals.
Clients: You will see a partial list of clients below the staff box with a link to view the entire clients list on its own page.
To see the full client list, click the "Clients" tab, which will take you to this page: Clients page. The client list is sorted by STARmeter with each of the reps listed next to each client. If you are having trouble locating someone on the list, try using your browser's Find function by clicking Ctrl + F and typing their name.
