Does IRIS guarantee a delivery date?
No. IRIS does not publish a fixed time from payment to USPS handoff or guarantee an arrival date. USPS transit estimates apply after mailing, not from checkout.
Letter and postcard delivery times
USPS lists a 1–5 business day First-Class Mail transit estimate after a mailpiece enters the mailstream. That estimate does not start at checkout or include preparation before mailing.
Payment is not postal handoff
IRIS does not publish a fixed time from payment to USPS handoff or guarantee an arrival date.
The stages below explain what order updates establish and what they do not.
Payment accepted
Payment or credit acceptance queues an order for processing; it does not confirm printing or USPS handoff. “Payment needs review” is a separate support state that must be resolved before fulfillment.
Print-partner preparation
A successful mailpiece-creation response means the print partner created a resource for the order. Creation and rendering reports do not prove physical printing is complete or that USPS has accepted the mailpiece. Holds, payment review, document or provider failures, and operational exceptions can delay preparation.
Postal handoff and transit
The USPS 1–5 day First-Class Mail estimate starts after entry into the mailstream, not at payment. Order events are provider-reported. The “Mailing activity reported” status alone does not prove USPS handoff; consult the specific events. Missing or late scans do not prove a particular physical location or stage.
Delivery and exception updates
IRIS shows the available provider-reported results. “Delivery reported” reflects a reported result, not an independent confirmation by IRIS. A “Delivery exception” may mean a return, reroute, or Certified issue; the specific event determines which. Neither an arrival date nor the availability of a signature record is guaranteed.
Certified Mail is not faster service. USPS offers a mailing receipt and tracking for eligible letters; IRIS displays tracking and provider-reported events when available, not a downloadable postmarked receipt. Weather, address problems, holidays, and USPS operations can delay transit. IRIS is independent of USPS.

Checking an order or requesting cancellation
Open your private order page using the link from your order confirmation to see the displayed status and available provider reports. A recorded event time may be the time IRIS received the report when the provider did not supply an event time.
Contact support for a concerning status, a cancellation request, or help interpreting a delay. Include your order number and displayed status, not document contents, financial or government identifiers, or passwords.
Need to cancel? Contact support promptly. Cancellation is not guaranteed after submission to the print network. See the cancellation terms, including the treatment of third-party costs already incurred.
Delivery questions
When will Certified Mail tracking appear?
The private order page shows a Certified Mail tracking number after it becomes available. Scan timing depends on the print handoff and USPS processing, and a letter may not receive a scan at every stop.
Does Certified Mail travel faster?
No. Certified Mail does not travel faster. USPS offers a mailing receipt and tracking, but IRIS displays reported events rather than a downloadable postmarked receipt.
Do postcards receive tracking updates?
IRIS shows postcard events when its print partner or USPS reports them. Some postcards may have few or no scan updates.
