Soccer within the US is governed by US Soccer and SafeSport.

Athletes and their communities are able to report alleged abuse and misconduct to SafeSport, US Soccer, or both. Both SafeSport and US Soccer allow anonymous reports to be made. 

If US Soccer receives a report of alleged sexual misconduct, it will promptly forward the report to SafeSport as SafeSport holds exclusive jurisdiction* over the response and resolution to such reports. 

To report alleged abuse or misconduct (either anonymously or non-anonymously) to US Soccer, you can use their form here or you can call their Integrity Hotline at (312) 528-7004.

To report alleged abuse or misconduct to SafeSport (either anonymously or non-anonymously), you can use their form here or you can call them at (833)587-7233.

*Exclusive jurisdiction means that only one entity (in this case SafeSport) has the power/legal authority to respond to something (in this case it is alleged sexual misconduct).
