Hello @Seller_Bj72luWmdLJHA,

Thank you for contacting Amazon Forums!

Adding to @Seller_7LrAV0m5llaI7's response, Amazon will decide the fulfillment center your product get shipped to by default. When you create a shipping plan, your shipment may be divided into multiple shipments, each directed to a different receive center or fulfillment center (referred to as distributed inventory placement).

The fulfillment centers are selected based on the products that you're shipping and where you're shipping from. Spreading your inventory across multiple fulfillment centers means that buyers may receive your products faster than they would if your inventory was located farther away. To better spread your products, we may route your shipment through a receive center, which receives units and then reships them to other fulfillment centers in our network.

I hope this information helps.

Please remember that if you need extra support you can always reach out to our Seller Support team.

Kind Regards,

-Josh
