Frontier Communications Phone Number
If you'd rather talk to Frontier directly instead of (or in addition to) reporting your outage here, their main customer service and technical support line is 800-921-8101, available 24 hours a day, 7 days a week for support and troubleshooting. This is the number to call if you want to confirm an outage on Frontier's end, get an estimated repair time, or troubleshoot equipment issues.
Reporting your outage on this site takes less time than a phone call and helps other Frontier customers near you see that they're not the only ones affected. Many people do both: report here for the community view, and call Frontier directly if the issue doesn't resolve on its own.
