# Can I merge multiple Customers into one?

You may have noticed multiple duplicate Customer records representing the same person and want to merge them. Unfortunately, Stripe does not support merging Customers.
Duplicate Customers are commonly caused by Payment Links or Checkout Sessions with `customer_creation` set to `always`, or by integrations that automatically create a new Customer record as part of their checkout flow.
To avoid creating duplicate Customer records, identify if a record exists in your Stripe instance for that specific customer. If you store your customer’s email address you can use it to filter the [Customer List API](https://stripe.com/docs/api/customers/list). You could also choose to store the Customer ID locally in your integration. If multiple Customer records exist for one customer, we recommend using the Customer with the most relevant data (for example, most recent payment method, additional details such as name and address).
Once you’ve identified the correct customer record (if one exists), use that Customer ID instead of creating a new record. Finally, if you are using Checkout and/or Payment Links, try setting `customer_creation` behavior to `if_required` in your integration.
