Calls From 1-800-746-6373: What is this Telephone Number? Suspicious 0 0 1.39K 1 Apr 1, 2020 2020-04-01T16:17:30-05:00 Apr 1, 2020 2020-04-01T16:20:55-05:00 Online Threat Alerts (OTA) The telephone number +1-800-746-6373 is or appears to be a sex line telemarketer. I received a few robocalls from the number and called it because I couldn't find any info about it. I found out it’s a phone sex line. So unless you want those services don’t call. But, I was told by some people that they were called and told to give out their SSN for a 2020 check.
