Did the Mail Run Today? How to Check USPS Delivery

5-second decision tree

Walk this in order. The first "yes" is your answer.

1. Is today Sunday? Standard mail does not run. (Exceptions: Priority Mail Express + Amazon parcels.)
2. Is today a federal holiday? See the 2026 list below. No standard mail today.
3. Is your area under a USPS service alert? Check about.usps.com/newsroom/service-alerts. If your ZIP or state is listed, mail is paused.
4. Did Informed Delivery email arrive this morning? If yes, the carrier ran. If no, the carrier may run later or had a route delay.
5. None of the above? Mail is running today — if nothing arrived by 8pm local, see the "missing mail" section below.

Mon–Sat: yes, mail runs

USPS operates a six-day delivery week. Letters, postcards, First-Class Mail, Priority Mail, Ground Advantage, Marketing Mail, and packages all move Monday through Saturday across virtually the entire country.

Saturday is a normal delivery day. This sometimes confuses people because UPS and many private carriers don't default to Saturday delivery. USPS does — and Saturday is when a lot of late-week First-Class Mail catches up with you. For details, see our Does USPS deliver on Saturday guide.

Typical delivery windows are 9am to 5pm in residential areas, but rural and high-volume routes can run as late as 8pm. The carrier's arrival time at your specific stop varies day to day — there is no guaranteed time-of-day even on a normal weekday.

Sunday: no (with two exceptions)

Regular USPS mail does not run on Sundays. Letter carriers don't work the route, retail Post Offices are closed (with rare exceptions for self-service kiosks), and your blue-box collection is paused for outgoing pickups.

Two narrow exceptions deliver on Sunday:

• Priority Mail Express — the only USPS service with a money-back delivery guarantee, delivered 365 days a year including Sundays and federal holidays.
• Amazon parcels — USPS has a long-running Sunday parcel-delivery contract with Amazon, mostly in metro areas with high package volume. If the package shipped via USPS as the final-mile carrier on an Amazon order, it can arrive on Sunday.

Anything else — First-Class letters, regular Priority Mail, Marketing Mail, certified mail — waits for Monday morning.

2026 federal holidays USPS observes (no mail)

USPS observes 11 federal holidays. On these dates, no standard mail is delivered and Post Offices are closed.

Heads-up: when a holiday falls on a Saturday, USPS observes it the prior Friday. When it falls on a Sunday, it observes the following Monday. For full holiday timing and the impact on certified mail and priority deadlines, see USPS holidays 2026.

Weather, disaster, and route suspensions

The famous "neither snow nor rain nor heat" line is from a 1914 New York Post Office inscription, not USPS policy. Modern USPS pauses service when carrier safety is at risk — blizzards, hurricanes, tornado warnings, wildfires, flooding, and active emergency declarations all trigger temporary suspensions.

Authoritative source for current pauses: about.usps.com/newsroom/service-alerts. That page lists by state and ZIP region. If your area is listed, expect mail to resume 1–3 days after the event clears.

Other reasons mail might not run on a specific day even when no broad alert is posted: route-level vehicle breakdown, individual carrier callout with no relief carrier available, or staff shortages at your local distribution center. These are not announced publicly — you find out by it not arriving.

How to confirm with Informed Delivery

USPS Informed Delivery is a free service that emails you grayscale scans of letter-size mail arriving the same day. It is the single best signal that your specific route ran.

1. Sign up at informeddelivery.usps.com with the address USPS uses for your mailbox.
2. Verify your identity (USPS uses a one-time code or photo ID check).
3. Each morning USPS plans to deliver mail to you, you receive an email with previews of the day's letters.
4. If the email arrived: mail ran for your route today.
5. If no email and it's not a holiday: mail may run later, or your route is delayed/suspended.

Informed Delivery only previews letter-size First-Class Mail; postcards, large flats, and packages are represented by package-tracking events instead. So an empty Informed Delivery email doesn't prove no mail arrived — just that no letters were scanned for your address that morning.

For tracking specific items rather than the whole route, see our USPS tracking not updating guide.

If mail didn't come and it's not a holiday

Walk these steps in order before contacting USPS.

1. Wait until 8pm local time. Carriers regularly run late, especially on heavy-volume Mondays and around peak holiday periods. Mail isn't officially "skipped" for the day until late evening.
2. Check service alerts. about.usps.com/newsroom/service-alerts — weather, fire, hurricane, or local emergency could be the cause.
3. Track any specific piece you're expecting. A piece showing "Out for Delivery" today on usps.com means a carrier is on your route — mail is moving even if it hasn't hit your box yet.
4. Ask your neighbors. If their mail came and yours didn't, the issue is at the box-level (carrier missed your stop) and your local Post Office can usually fix it next day.
5. If 2+ business days pass with no mail and no service alert, file a service request with your local Post Office or call 1-800-ASK-USPS. See our USPS lost mail guide for the full escalation path.
