There are two primary offices: Ohio and Texas, plus one for the airline. However, if this is court ordered paperwork, it needs to be sent to the registered service agent that accepts those items on behalf of the company. There's one for each state and they will forward necessary items to the payroll office. If it's something else, like a direct deposit update, your center admin should know where to send it.I'm currently filling out a document that is asking for address of payroll office. Is there only one for US employees or are there many different ones?
