Short answer: Mail delivery and post offices generally continue operating during a federal government shutdown. The U.S. Postal Service funds its regular operations primarily through the sale of postage, products, and services.
What normally continues
- Residential and business mail delivery
- Package acceptance and delivery
- Retail post office service
- PO Box access under the facility’s ordinary schedule
- Tracking and online USPS tools
Normal service standards still apply, but a shutdown does not protect the network from unrelated delays such as severe weather, local emergencies, transportation disruptions, or holidays.
Why USPS is different
USPS is an independent establishment of the executive branch with a distinct financing structure. Its operating expenses are generally paid from postal revenue rather than the annual discretionary appropriations that can lapse.
This does not mean every service associated with a post office is insulated from a shutdown. A postal location may accept passport applications, for example, while passport processing is performed by the State Department.
Checks, tax forms, and government notices
USPS can deliver a government check or notice when an issuing agency sends it. Whether the agency processes or sends the item on time is a separate question. Social Security payments generally continue, and direct deposit avoids postal transit. Some agency correspondence and manual processing can slow.
Filing and response deadlines do not automatically disappear during a shutdown. Preserve proof of mailing when a deadline matters.
If mail is delayed
- Check tracking when available.
- Review the USPS service alerts for local disruptions.
- Contact the sender to confirm the item was issued.
- Use the official missing-mail process if the item meets its timing requirements.
- Avoid sharing tracking or identity information with accounts that contact you unexpectedly.
