# Billing Statement Identifier

The Billing Statement Identifier field enables merchants to define the line of text that will appear on their customers’ credit card statements, in association with the related charge.

Billing Statement Identifier example: `website.com|3101231234`.

**Note:** The asterisk is a reserved character that is not allowed in the Billing Statement Identifier.

The billing statement Identifier is a part of the text that appears on the customers credit card statement along with other info such as the billing description and MCC. For more details, see [Billing Description](Billing_Description).

Customize a Billing Statement Identifier in Subscribe using either of the following:

* Billing Statement ID on a Billing Plan or Product for a Subscription in the Subscribe Portal
* `billingStatementIdentifier` attribute in the REST or SOAP API

In the API, for credit card-based recurring billing, set the attribute for the `BillingPlan`, `Product`, `AutoBill` or `Subscription` object.

Subscribe will then insert the identifier into every Transaction generated for the `AutoBill` or `Subscription`, and the identifier will appear on your customer’s next billing statement.

If you set the attribute on all three objects, the order of precedence is:

1. `BillingPlan`
2. `Product`
3. `AutoBill` or `Subscription`

For real-time Transactions, set the `billingStatementIdentifier` attribute for the `Transaction` object.
