Import Customers Online

Upload and manage multiple customer profiles at once from the online Square Dashboard with the bulk import tool.

Upload Customer Profiles

From your online Square Dashboard, you can also upload customer profiles in bulk. To do so:

  1. From the Customers tab of your online Square Dashboard, click Import/Export.

  2. Drag and drop your customer CSV file into the upload field or click select it from your computer to upload the file > click Continue.

  3. **All customers added will be within a new group created for your import. **

  4. Confirm your customers’ details are in the correct columns. If there are errors, click the drop-down menu to the right of the field and select the correct field.

  5. Note: If you need to add customer details that don’t currently fit into the default fields, you can add custom fields to your directory before importing contacts.

  6. Click Import to move this group to your Customer Directory.

Import Customer Profiles

When importing via CSV, you can set an opt-in status per each email you’re importing by having a separate status column, titled Email Subscription Status. You can set the status of the email address to Subscribed, Unsubscribed, or Unknown.

Note: If you are importing customer information for use with Square Marketing, only send marketing communications to customers who have consented to receive marketing emails from your business. You are responsible for ensuring the customers on your list have given explicit permission to contact them and for compliance with all applicable laws. Review our terms for more information.

File Type Support

Prepare the customers you would like to import in a tool, such as Excel, and save it as a .CSV file. Data that is not saved as a .CSV file can’t be uploaded into our system.

Field Type Support


The preferred date format is the ISO 8601 format (YYYY-MM-DD), but we also support:

  • YYYY-M-D

  • YYYY/M/D

  • YY-M-D

  • YY/M/D

  • M-D-YYYY

  • M/D/YYYY

  • M-D-YY M/D/YY

Phone Number

The preferred phone number format includes the phone’s country code in E.164 format. If no country code is provided, it may be assumed based on the customer’s country.


To make sure your address is entered in the correct format, be sure to separate each part of your address into a different column and correctly match each part of your address to the correct field. We suggest you name your columns: address-country, address-street, address-zip, etc.


The preferred format for toggles is Yes/No, but Y/N and True/False are also supported.


Both integers and fractional numbers are supported.

Email Subscription Status

You are able to set the status to Subscribed, Unsubscribed, or Unknown. Any cells on the CSV with a blank or null value will be populated with an Unknown status. Email addresses that are uploaded and marked as Subscribed need to be immediately available to market to.
