Update Customer Records

How to tag customer records, combine matching customer records, and update existing customer records with a CSV file.

Customer records in ShipStation can be tagged, combined, and updated via CSV upload. Customer records cannot be deleted or made inactive in ShipStation.

A tagged customer record will apply that tag to all orders that import for that customer. This is useful if you need to filter orders or apply automation rules with a tag as the trigger.

You might want to combine customer records if you have multiple entries for the same customer. Combining will allow you to tag a single customer record and view their order history in a single record.

The sections below discuss how to tag, combine, and update customer records.

Tag Customers

Add a tag to a customer if you want every order from that customer to be tagged when it imports. Tag a customer to indicate special situations (loyalty reward member, fraud risk, etc.) for your shipping crew that help ensure no special instructions are overlooked.

Read the section in our Automation FAQ to learn how using tags to identify customers can improve your workflow. 

To remove tags, repeat the above steps and uncheck the selected tags, then click Save.

Learn About Order Tags

Read our Order Tags article to learn more about using tags within ShipStation and how they are useful.

Combine Customer Records

Combine duplicate customer records into one surviving customer when one person at the same mailing address has orders from multiple email addresses. Other customer records you select for merging will subsequently absorb into this surviving customer record.

Update Customer Records via CSV

Download the CustomerImportSample.csv template from the Customer Import pop-up. You will need this template to update your customer records via CSV. 


Enter all of the customer data you need into the appropriate fields and save your file. You can then import this file to update existing customer records, as well as create new customer records.

ShipStation requires that each customer has a unique identifier, either a username or email address, present in the file. Use the email for both if no username is available. 

CSV imports only update customer records associated with the Manual ShipStation marketplace. Customer records created from other selling channel imports will not be updated using this method.

You can use the customer address information stored in this database to create manual orders for the customer or apply tags to orders. ShipStation will not use this address to override order data imported via a selling channel or Order CSV. New orders created via import will use the address as supplied during import.

If a subscription or return customer needs an address updated, you should update it at the order source so it imports correctly.
