Tax code notice sent to wrong address

I received a tax code notice in the post today. I live alone do didn't bother to check who it was addressed to and when I opened it the name was someone who has never to my knowledge lived at this address. The NI number was not mine. What should I do about this?

Hi,

If you contact our Income Tax department, we can take the details of who this was addressed to and send a referral to have this updated.

Thank you.
