Mail is not delivered on July 4th. USPS treats Independence Day as a federal holiday, so letter carriers don’t run routes, post offices close their retail counters, and items sitting in collection boxes wait until the next business day. In 2026 the calendar makes the pause longer than usual: July 4 falls on a Saturday, so USPS observes the holiday on Friday, July 3. Your last regular delivery is Thursday, July 2, and service resumes Monday, July 6.1United States Postal Service. Employee and Labor Relations Manual – 518 Holiday Leave
What Stops and What Keeps Moving
Every standard mail class pauses on the holiday. First-Class Mail, Marketing Mail, periodicals, and regular package services all halt. Carrier pickup doesn’t happen. Anything you drop in a blue collection box on the holiday sits until operations resume. Post Office Box access is also unavailable.2United States Postal Service. Post Offices Will Close July 4th in Observance of Independence Day
The one product that may still move is Priority Mail Express, which USPS advertises as delivering seven days a week, 365 days a year, with limited exceptions.3USPS.com. Mail and Shipping Services If you need something delivered on the holiday itself, that’s the only USPS service that might get it there. “Limited exceptions” means it isn’t guaranteed at every location on every holiday, so check before you rely on it.
Post Offices and Self-Service Kiosks
Retail counters are closed on the observed holiday. You can’t buy stamps at the window, ship a package with a clerk, or get help in person. Self-service kiosks at select locations stay accessible around the clock, including on holidays. They take credit and debit cards and handle most common transactions, such as weighing packages and printing postage for Priority Mail Express, Priority Mail, First-Class, and Parcel Post.2United States Postal Service. Post Offices Will Close July 4th in Observance of Independence Day
One caution: dropping a package at a kiosk on the holiday doesn’t mean it gets processed that day. It waits with everything else until the next business day, and the postmark reflects processing, not the moment you paid the kiosk.
UPS, FedEx, and Amazon
The private carriers follow the same holiday. UPS suspends pickup and delivery on July 4th, and UPS Express Critical is the exception that operates every day of the year. UPS Store hours vary by franchise.4UPS. Holiday Shipping Schedule FedEx Ground and Express are both closed on Independence Day. Amazon generally does not deliver on July 4th, since its logistics network largely follows the same federal holiday calendar. If a tracking page shows an estimated delivery date of July 4, or of the observed Friday in 2026, expect the package the next business day.
Why the 2026 Closure Starts on Friday
The federal observance rule is fixed. When July 4 lands on a Saturday, the preceding Friday becomes the observed holiday. When it lands on a Sunday, the following Monday takes its place.1United States Postal Service. Employee and Labor Relations Manual – 518 Holiday Leave Mail delivery and post office closures track the observed date, not the calendar date. That’s why the 2026 gap starts a day earlier than the actual holiday. Anyone assuming mail will still arrive on Friday because “the 4th is Saturday” will be caught off guard.
Deadlines and Postmark Dates
If a legal or tax deadline falls on July 4th or its observed date, it automatically extends to the next business day. The IRS applies this rule to filing and payment deadlines.5Internal Revenue Service. When to File Federal courts apply the same principle under the Federal Rules of Civil Procedure: when the last day of a filing period lands on a legal holiday, the deadline extends to the next day that isn’t a Saturday, Sunday, or holiday.6Legal Information Institute.

Postmarks are where people slip up. The date USPS stamps on your envelope reflects when the processing facility handled it, not when you dropped it in a box, so a piece left in a collection box the day before a holiday may carry a later postmark than you expect.7USPS About. Postmarking Myths and Facts If the date on your postmark matters, take the item to a post office counter before the closure and ask for a manual postmark. The clerk will stamp it by hand at no charge.
