In ShipEngine, shipping origin address information is paired with return address information and can be saved as a warehouse (warehouse_id). The return address information typically displays prominently on a shipping label, and the origin address information is used to calculate shipping rate quotes.
In ShipEngine, you can create more than one shipping location and save them as warehouses. There is no limit on the number of warehouses you can have in your account and this is the same for all plan levels.
Some fields are required so that certain services work properly. For example, UPS requires Origin Street 1, Origin City, Origin State, Origin Postal Code, and Origin Country in order to return accurate rate quotes.
Feel free to create multiple warehouse locations if you have multiple origin or return addresses. Remember that you can only enter shipping origin addresses that match the country of origin you selected when you signed up for a ShipEngine account.
Note: If you have warehouses based in different countries, you will have to set up a ShipEngine account for each country you will be shipping from. Currently we have support for Ship From Locations based in the US, Canada, the UK, and Australia.
