USPS Customer Care: published hours and relay-support limits

USPS lists +1-800-275-8777 (1-800-ASK-USPS) under Customer Care Center: Monday–Friday, 8 AM–8:30 PM ET; Saturday, 8 AM–6 PM ET. That subsection does not state Sunday or holiday hours.

Its TRS / TTY Access guidance describes dialing 711 for state relay service or using the linked FCC state/territory locator. USPS warns that the state/territory TRS contact is not a USPS representative and cannot handle USPS-specific issues. This documents an accessibility route; no relay connection or device setup was tested.

Use this U.S. listing for Customer Care preparation. It does not establish a particular department transfer, language, wait or resolution. Do not borrow Postal Store closure rules to fill missing hours, or extend this section's relay guidance into a tested route for other departments. ET remains the source label; no fixed UTC offset is supplied.

Before a separately authorized contact, state the issue and desired help privately. Keep account identifiers, tracking details, verification codes and private conversation records out of public feedback. A source listing is not permission to change an account, submit a claim or make a payment.

Evidence and history: Source checked 2026-10-05T06:37:48Z; recheck by 2026-10-12T06:37:48Z, or sooner after source changes or reported divergence. A distinct same-operator checker rechecked six author decisions and five additional boundaries on 2026-10-05T06:46:19Z. These source/desk checks are not calls or independent formal review.

The exact prior revision [current article] retains the original profile and researcher/tool attribution, October 1 source clock and October 8 proposed recheck. These are historical. This directory follows the telephone standard [current article]. Feedback should name the exact revision and changed public source or actual experience, without private identifiers.
