How long does mail take from state to state?

What does the USPS delivery time map show?

Each state is shaded by the number of days USPS most often gives a First Class letter from the state you pick, from 2 days in the lightest blue to 5 days in the darkest. Pick a state from the list or tap one on the map, and hover over a state to see its usual range.

How long does mail take from state to state?

Of all the letters that could go between two different states, weighting each state by its population, USPS's directory gives 2 days to 3 percent of them, 3 days to 21 percent, 4 days to 37 percent and 5 days to 39 percent. Only 46 trips between two states most often get 2 days, among them New York to Pennsylvania and New Jersey to New York. At the other end, 556 trips get 5 days for nearly every letter, including California to Florida and Florida to California, and 5 days is the longest standard First Class Mail has.

How long does mail take in the same state?

A letter that stays in its own state usually gets 2 or 3 days. Counting every state, USPS gives 2 days to 43 percent of those letters, 3 days to 44 percent and 4 days to 13 percent. Letters most often get 2 days inside 20 states, among them Texas and Florida, and 3 days or more inside 31, among them California and Pennsylvania.

Which states can reach the most people in 3 days?

If you sent one letter from Washington, DC to every person in the country, USPS would give 61 percent of them a standard of 3 days or less, and from Illinois the figure is 47 percent, the two highest. Alaska and Hawaii are at the bottom, since almost every letter from them to another state gets 5 days, and among the other states Wyoming and South Dakota are lowest at 2 percent each. The table gives the figure for every state.

Is this map the same for packages?

No. These days are USPS's standards for First Class Mail letters and cards. Priority Mail and USPS Ground Advantage packages have their own service standards, which USPS also publishes by ZIP code, so a package between the same two states can have a different number of days.

How do I find the exact days for one letter?

A state covers many ZIP codes, and a single letter has one number. Our delivery time tool gives USPS's days between any two ZIP codes and the date to expect the letter, and each state's page above lists the usual days from that state to all the others.

How were these days worked out?

The days come from USPS's service standard directory for First Class Mail, effective October 1, 2026, which we download from USPS's Service Standards Files API. It lists 849,106 pairs of 3 digit ZIP areas and 13,297 ZIP codes whose letters get a different number of days than the rest of their area, because since 2025 USPS sets the starting point by 5 digit ZIP code. For each pair of states we took every populated ZIP code in the first state as a starting point and every 3 digit ZIP area of the second as a destination, and weighted each pair by the people who live at both ends, using the Census Bureau's 2023 population counts. The map shades a state by the most common number, and "usually" is the range that covers the middle 8 of every 10 letters.

A service standard is USPS's target for a stamped letter mailed before the day's last pickup, and First Class Mail has no delivery guarantee. Sundays and the 11 federal holidays USPS observes don't count as delivery days, which the guide on letter delivery times explains.
