# How Can I Send My Shipment to One Fulfillment Center?

You can elect to participate in Amazon’s “Inventory Placement Service,” where Amazon will assign **units of a single product/ASIN** to a single fulfillment center. You are only responsible for sending your shipment to that one assigned fulfillment center; after the shipment arrives, Amazon will split it up and send it to different fulfillment centers for you. 

The default [FBA](https://www.flexport.com/glossary/fulfillment-by-amazon) service is “Distributed Inventory Placement” where Amazon may assign units of a single product/ASIN to multiple Amazon fulfillment centers when you [create a shipment plan](https://www.flexport.com/help/326-amazon-us-shipment-plan).

## Can I choose which fulfillment center a product is assigned to?

No. Amazon will determine which fulfillment center a shipment of a product is assigned to. 

## Does this service guarantee that my shipment won't be split into multiple fulfillment centers?

No. If you have multiple products/ASINs in one shipment, the shipment may still be sent to multiple fulfillment centers. If you have different unit types of a single product (ex. standard size vs oversize), they may be directed to different fulfillment centers. 

See [Amazon’s Help Center](https://sellercentral.amazon.com/gp/help/external/200735910) for **program fees** and more information.
