I went to college board to send my SAT scores and the next say i got a message from a college stating that they needed my score and then I got the message again a week later. Also, how do I know they got my transcript for sure? I don’t know who to contact or where to check.
Most schools have an admissions portal where you can check your application status. If you got a confirmation email when you submitted your application there would be instructions about setting up the portal.
You can contact admissions directly and ask them to check your file.
It usually takes a week or two (sometimes longer!) for a college to realize it has received your transcript and to mark it received. Some offices are very disorganized and/or backlogged. But call the admissions office if you’re nervous about it.
