Green Check Marks

[Ingenuity]

Over the last 3 weeks I have noticed that there are green check marks next to certain names in my contacts that call me. What do the green check marks mean and why are they just now popping up near certain contacts in my phone. I have a Galaxy S10 plus

i think that's to let you have seen them

The green tick will signal a verified caller. Not all networks have them, it just signifies they are a known number and not a cold caller or spam caller.

What is meant by a known number?

A number listed in contacts? A number for a call that has been answered? A number for a call that came in but was not answered?

Well, I just received a green check call from a cold or spam call.  Don't trust the check!!!
