Is There Mail Today? USPS Delivery Checker

5-second decision tree

Walk through these questions in order. If you answer yes to any of them, you will not be getting standard mail today.

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. An alert may mean delays, limited service, or a temporary suspension, depending on what USPS reports for your area.

Monday through Saturday: yes, mail runs

USPS operates a six-day delivery week. Letters, postcards, First-Class Mail, Priority Mail, Ground Advantage, Marketing Mail, and packages can all be delivered Monday through Saturday.

Saturday delivery sometimes confuses people simply because Saturday is part of the weekend. I received so many questions about it that I wrote an entire guide about whether USPS delivers on Saturday.

Some people actually do not want their letters delivered on Saturday. If you are mailing something to a business, you may want someone there to receive it. I have had customers email asking whether we could hold their mail on Friday or have it delivered the following Monday. Unfortunately, mail is difficult to control that precisely, but we can try to work something out when timing matters.

Certified Mail requires a signature. If nobody is there to sign, USPS leaves a notice with instructions for scheduling redelivery. In that situation, the missed Saturday delivery can actually work in your favor.

Sunday: no (with two exceptions)

I don't get asked about Sunday delivery nearly as often as Saturday delivery. To a lot of people's surprise, some packages do make their way through USPS on Sundays. Regular letters and most other mail do not run, retail Post Offices are closed, and blue collection boxes generally are not picked up until the next collection day.

The two main exceptions are:

• Priority Mail Express: the only USPS service with a money-back delivery guarantee. Sunday and holiday delivery may be available in eligible areas.
• 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.

First-Class letters, regular Priority Mail, Marketing Mail, and Certified Mail wait for Monday morning.

What counts as mail today?

Here's a quick guide for each type of mail. The short version is that Priority Mail Express is the USPS service backed by a money-back delivery guarantee, although eligibility and exceptions still apply. Use the chart below as an easy reference for everything else.

2026 federal holidays USPS observes (no mail)

This is where I've gotten tripped up, as I mentioned above. Holiday schedules do not always work the way I expect them to. For 2026, USPS kept Post Offices open and delivered normally on Friday, July 3, then closed on Saturday, July 4. Check the chart below before making the trip. If you want the full breakdown, our USPS holidays 2026 guide goes into more detail.

Weather, disaster, and route suspensions

The famous "neither snow nor rain nor heat" line is from a 1914 New York Post Office inscription. Unfortunately, if you're waiting for a random letter in the middle of a hurricane, you're probably going to keep waiting. The saying is pretty sweet, but it has never been official USPS policy, and modern safety rules do not treat it as a promise. Check USPS Service Alerts to see whether weather or another emergency is delaying mail in your area.

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, so you usually find out when the mail does not arrive.

How to confirm with Informed Delivery

If you haven't tried Informed Delivery and you're obsessed with knowing where your mail is like me, this is an amazing tool. I know what USPS expects to bring me that day before I even check the mailbox. I don't think many people are mail junkies quite like me, but I love it. Here's what the daily email looks like.

USPS Informed Delivery is a free service that emails you previews of mail expected soon. It is one of the easiest ways to see whether mail is moving toward your address.

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. USPS sends a Daily Digest with previews of letter-size mail expected soon.
4. If the email arrived: USPS Sends you an email with actual scans of what is on the way to your mailbox.
5. If no email arrived: This just means nothing is immediately headed to your mailbox.

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, a hurricane, or another 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, contact your local Post Office or call 1-800-ASK-USPS. For a specific missing piece, use the official USPS Missing Mail page.
