Is the post office open today?

Post office closures in 2026 and 2027

The table lists the days counters close for each holiday, after applying the Postal Service rule: a Saturday holiday stays on Saturday, a Sunday holiday moves to Monday. The last column says whether blue boxes are emptied, which follows the two lists of the Postal Operations Manual.

Three days of 2027 differ from the federal calendar. Juneteenth and Christmas fall on a Saturday, so post offices close that Saturday while their Friday is a normal day. New Year's Day 2028 is also a Saturday: counters are open on Friday, December 31, 2027 and closed the next day.

The Saturday rule, explained with July 4, 2026

For federal employees on a Monday to Friday schedule, a holiday that lands on a Saturday is moved to the Friday so that they do not lose it. The Postal Service delivers mail six days a week, so moving the holiday would close a working day and leave the Saturday open. Its memorandum for Independence Day 2026 spells out the result: Friday, July 3 was a regular business day for retail and delivery, and Saturday, July 4 was the holiday, with no regular delivery and no collection.

For a Sunday holiday the logic runs the other way. Counters are already closed on Sunday at most offices, so the holiday is observed on the Monday after, as with Independence Day 2027 on Monday, July 5, 2027. On that Monday, offices close and mail does not move except for the services that always run.

Widely observed or not: why some boxes are still emptied

The manual sorts the eleven holidays into two groups. Six are widely observed: New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. On those days almost every business closes too, so collection boxes are not emptied and no letters are processed. The five others, Martin Luther King Jr. Day, Presidents' Day, Juneteenth, Columbus Day and Veterans Day, are holidays for the Postal Service but not for much of the economy. Offices still close and regular delivery still stops, but carriers empty collection boxes so that mail posted by businesses keeps moving. The Columbus Day memo and the Juneteenth memo describe that pattern.

Sundays, evenings and self-service kiosks

Most post offices have no Sunday counter hours, which the checker shows as mostly closed. Some large city offices and airport facilities keep limited hours, and self-service kiosks inside many lobbies sell postage and accept packages when the lobby is open, sometimes around the clock. Packages delivered by the Postal Service for large retailers can arrive on Sunday in many areas, but letters are not delivered. The mail delivery page explains what moves on those days.

Planning around a closure

Before a long weekend, count the days a letter will sit in the system. A letter posted on the Friday before Labor Day is not collected again until Tuesday morning, while one posted on the Friday before Columbus Day can still be picked up on the Monday. For a deadline that depends on a postmark, such as a tax return, the date on the postmark is what counts, so avoid relying on a holiday collection. The business days counter gives the number of working days between two dates without federal holidays, and the post office holidays 2027 page lists every closure of next year in one place.
