Third Stimulus payment haven't received yet?

Hi,
I was checking the Get My Payment system, and it says the check was mailed to me on March 30th, which was a week ago. I haven't received it yet, and I'm worried because I think someone may have stolen my ssn and used it to get the check mailed to them. Is it weird that the check has taken so long to be mailed, or is that normal?
