Because ONEOK operates primarily as a business-to-business (B2B) midstream provider rather than a retail utility, they do not utilize a traditional public customer service hotline. To completely bypass automated menus, call the Main Switchboard at (918) 588-7000 during central business hours. State the specific pipeline, region, or business department you need to reach, and the receptionist will drop you directly into that team's live internal directory.
