Retrieving a Transaction ID
If you’ve purchased an upgrade for your WordPress.com blog, our payment processor has generated a unique transaction ID to identify your transaction. It’s a string made up of both letters and numbers. We may request the transaction ID to look up your purchase, or to verify your account ownership.
If You Paid With a Credit or Debit Card
Locate the email receipt you received after paying for your upgrade. The transaction ID is in the top right corner of the Order Summary section. You will see either a 17-digit code, or a code starting with “ch_”.
If you have access to your WordPress.com account, you can view all of your WordPress.com receipts by navigating to the Me section of WordPress.com, choosing the Manage Purchases option from the sidebar, and then clicking the Billing History tab.
From the list of receipts, you can click View Receipt and the transaction ID can be found under Transaction ID:
If You Don't Have Access to the Receipt
Sometimes you need to verify your account or purchase, but don’t have the email receipt. For some payments processed at WordPress.com, you’ll find a 10-digit unique code for the transaction on your bank or credit card statement, right after “WPCHRG.COM”.
If your statement displays the digits 8772733049 next to the transaction, or no code is present, your payment was processed by PayPal. Please see the following section.
If Your Payment Was Processed Through PayPal
We use PayPal to process many of our transactions, whether you paid with your PayPal account or with a credit card. You can locate a transaction ID in your PayPal account, or if you used a credit or debit card directly, contact PayPal.
