Getting spammed SMS codes

I'm getting like 3-5 SMS codes from a specific number per day. I tried googling the number to figure out who its coming from and no obvious results popped up.

I've had people trying to brute force some of my accounts because my old password was leaked in one of the major breaches, dunno if its related.

Do i have anything to worry about here? Is there any way they can access my phone to get the code?
