If these calls reach you

  • Don't confirm your Medicare or insurance number to a caller. Medicare won't cold-call you to sell braces, test kits or plans.
  • Don't press a key to “opt out”. It tells the dialer your line is answered.
  • Because the number changes every time, blocking single numbers won't keep up. Turn on your carrier's free spam filter: iPhone, Android, Verizon, AT&T, T-Mobile.
  • Report it at donotcall.gov. Every report is a row in the data this page is built from.

Questions about this campaign

Is this one company calling?

We can't tell, and we don't name anyone. What the public FTC data shows is 836 different local numbers in 41 prefix blocks drawing 869 complaints about medical & prescriptions calls between 2026-08-03 and 2026-09-30, with the same call style and timing. That is how a single operation cycling caller IDs looks, but several operations using the same dialing method would look the same.

Why does each number only get one or two complaints?

96% of the numbers drew exactly one complaint in 60 days (1.0 per number on average). Robocall dialers display a fresh number, often spoofed, for each batch of calls, so blocking one number rarely stops the next call. Carrier spam filters and call-blocking apps work on the pattern instead.

When do these calls come in?

33% of complaints that give a time describe calls between 9am and 12pm, and 99% came Monday to Friday, most on Thursdays.

How do I stop these calls?

Don't confirm your Medicare or insurance number to a caller. Medicare won't cold-call you to sell braces, test kits or plans. Don't press a number to be removed; it confirms your line is live. Turn on your carrier's spam filter, block the number, and report the call at donotcall.gov so it's counted in the public data.
