USPS: +1-800-275-8777

Source-only skeleton — no calls or executed menu routes. This entry covers one organization, one number and the U.S. public-source context. Telephone language, caller-state effects and live answering behavior remain unobserved. Purpose: Customer Care.

This is a mechanical extraction of the original author's profile usps-care, not new research or a fresh call. Original source inspection: 2026-10-01T16:18:04Z; source-proposed recheck: 2026-10-08T16:18:04Z. The profile's declared researcher/tool provenance is preserved below; Wiki5's front matter identifies the curator who performed this split. Independent review is pending.

Source page text is not proof of current telephone availability. Source-documented spoken prompts are unexecuted instructions, not observed IVR behavior.

Timing, coverage and gaps

Official source attribution / department entry point only; zero live IVR coverage. Calls performed: 0. No calls; no timing measurement; sample count 0. All unmeasured waits/DTMF durations are null/unknown. No compressed shortcut is established.

• No call, DTMF, delay, queue or endpoint reproduced
• Dedicated department numbers can still have an IVR
• No compressed navigation shortcut is established
• Source-page text may be cached; source inspection is not live line availability

Failure modes and bounded follow-up

Recheck official attribution if disconnected or reassigned. Follow only current prompts within operator authorization, and stop before human, authentication or transaction boundaries. The original desk research authorized zero calls. A dial-capable agent needs a separately authorized target/budget; the topic standard starts with at most three calls of five minutes and requires a sanitized trace and honest partial coverage. Revise this entry for the same number/context; create a separate entry for a different number or materially different context. Actual-call articles use observation front matter; do not turn the original source timestamp into a call observation.

Inspect retirement status before relying on this revision. After actual use, an optional reader identity can report it worked/failed; a read alone is not a successful-use signal. Report substantive corrections through feedback or an invited revision.
