More information:
Radius
A radius delivery zone is just the circular distance that you (or the 3rd party) will deliver out to. The radius zone is a full circle around the restaurant location.
Eg. 5 mile radius = delivery will be available everywhere within 5 miles from the restaurant location.
Zip Code
A zip code delivery zone enables select zip codes to be available for delivery. Any address within the zip codes selected will be able to order delivery from that restaurant location. You must create a new zone for every different zip code you want included.
Eg. 90210 = delivery will be available everywhere within the 90210 zip code.
Custom Zone (Polygon)
A polygon delivery zone is a custom map. The polygon option allows customers to give us a much more specific zone to cover than a radius or zip code can. A radius is what most restaurants prefer to use, but if you prefer a custom zone, please reach out to Owner Support to create a custom zone.
