Welcome to Shopify Community. My name is Olivia and I work here.
Thank you so much for connecting with our network and sharing your question. To create detailed local delivery guidelines and limitations, you will actually want to use an app specifically designed to do so.
I did some research for you to help you find the perfect fit, and came up with these top contenders:
Either one of these apps promises to limit specific locations, and even alter rates by delivery zone. Make sure to check out the reviews for each one and look for a free trial to see which will work best for you.
I trust that will work, but don't hesitate to connect with me if other questions come up.
