About USPS support
USPS lists at 1-800-275-8777 as its customer-care line, answered Mon-Fri, 8 AM-8.30 PM ET. Callers typically use it for account trouble, order or booking issues, refunds and service complaints. For anything that is not urgent, writing to spam@uspis.gov usually gets a written reply you can refer back to. If the service itself seems broken, glance at its live status page first — the problem may be an outage rather than something on your account.
