Contact USPSPERFACT

Contact USPSPERFACT for product questions, order support, shipping information, returns, or help choosing a quantity for a mailing project.

Email customer support

Email service@uspsperfact.com. For an existing order, include the order number, purchaser name, delivery ZIP code, and a concise description of the issue. Do not email full payment-card information.

Product and equipment questions

If you are buying rolls or larger coils for mailing equipment, include the product URL, required quantity, roll or core requirement, stamp spacing, and feed-direction information available from your machine supplier. We cannot confirm equipment compatibility without those details.

Address changes

Send address-correction requests as soon as possible. An address cannot normally be changed after an order has entered shipment, but support will confirm the available options.

Before contacting us

You may find an immediate answer in our FAQ, Shipping Policy, or Return Policy.
