Does amazon allow to using same account/tracking id for multiple sites?

I have a few websites where I get a small traffic that I'd like to monetize, so I'm going to sign up with amazon associates program. Should I have a separate account or a tracking tag per site or does Amazon allow using same affiliate tag for multiple sites?

I just don't want to get banned.

Thanks!

As long as all of the sites stick to the TOS you can use the same account on as many sites as you like, same tracking codes too. However, I'd recommend setting up different tracking ids within the same account for different sites as it makes it much easier to see which sites are performing best if you ever decide to scale up and makes it easier to snapshot earning proof for potential buyers if you ever come to sell a site.

You can use all the websites that you want but I think that using one tracking for every site can be very useful for your affiliate strategy
