Where do I find the creator's address?

The creator's address is on their job page, in the Ship to box — with a copy button for your shipping label.

On the creator's job page, in the Ship to box. It's there as soon as you accept the creator.

Before you ship: the Ship the product to (creator name) card shows the address at the top. Click the copy icon to paste it onto your shipping label.
After you ship: open Shipment details — the address is there with the carrier and tracking number.

Good to know

For privacy, creators' emails and phone numbers are never shared. If the carrier needs a contact, ask the creator in the chat.
