Where can I see the Google Calendar phone numbers from which SMS come from?

Question

Google

Good afternoon.

Please tell me if there is a complete list of Google calendar phone numbers from which SMS reminders of events come. I would like to put them in the phone book and set up auto-delete rules after a certain period.

For example, they come to me from phones with the Finnish code: [phone] *** (random by asterisks, but sometimes repeated). I do not want to score from 0 to 999, since the contact will be too heavy.

By the way, I wonder, what numbers does it come from to you? It may be different in different regions.

Thank you.

Answer 1

It comes to me from "GOOGLE" (I live in Belarus). So it most likely depends on the agreement with the operator.
