As of my last knowledge update in January 2022, Facebook doesn't provide a direct customer support phone number for general inquiries or assistance. However,(1-855-974-1385) you can try a few alternative methods to get in touch with a live person or seek assistance:
Facebook has a comprehensive Help Center that covers a wide range of topics. You can access it by clicking on the question mark icon in the top right corner of the Facebook website or app and selecting "Help & Support." This resource may help answer common questions without the need to contact support.
