What type of Verizon Text comes from these numbers?

[Eagle20]

The first time I received a Verizon Text I created a "Verizon" contact. Since then I've received various texts with authorization codes from support, for credits applied to my account, and reminders that a callback is scheduled. But I stupidly added the numbers to the same "Verizon" contact, and now have no idea what type of text comes from what number.

Can someone tell me what type of text (eg; alert, reminder, etc.) comes from these numbers? 

+90 (004) 000 10 00

+90 (007) 000 38 05

+90 (007) 000 50 06

+90 (008) 000 40 00

+90 (008) 000 40 07

+90 (009) 000 10 12

555-5

800050001020

Thanks in advance to anyone who replies!

I have just received 2 separate text messages From +90(009) 000 10 12 and +90(008) 000 40 00 saying  Welcome to My Verizon. If you did not register for My Verizon access, please contact us immediately at (800)922-0204 and the other text message said one of the mobile numbers on my account (they listed the number) had registered for My Verizon access. If you believe this is an error, please call us at (800) 922-0204. Scam??? I’m thinking yes but not sure
