How long does a letter take within Indiana?
USPS's directory gives 2 days to 37 percent of the letters that start and end in Indiana, 3 days to 56 percent and 4 days to 8 percent. About 27 percent of the people in Indiana live in ZIP codes whose letters get a day more than the rest of their 3 digit ZIP area, which is the 2025 rule for post offices more than 50 miles' drive from the plant that sorts their mail. If you mail from one of those towns, expect the slower end of each range on this page.
Which states get mail from Indiana fastest?
USPS most often gives 3 days or fewer to letters from Indiana bound for 7 other states, led by Illinois, Kentucky, Michigan and Wisconsin. To Illinois, 95 percent of letters have a standard of 3 days or less.
Which states take the longest from Indiana?
USPS gives 5 days to most letters from Indiana going to 12 states, including California and Washington. A letter on one of these trips that goes out with Monday's pickup is due on Saturday, or a day later when a holiday falls in the week.
How much of the country is within 3 days of Indiana?
If you sent one letter from Indiana to every person in the country, Indiana included, USPS would give 36 percent of them a standard of 3 days or less. That ranks Indiana 10th of the 50 states and DC, and the state in the middle of that list is at 22 percent.
How do I find the exact days for one letter?
Each range on this page covers many ZIP codes, and one letter has a single number. For example, USPS gives a letter from ZIP 47906 in Indiana to ZIP 92336 in California 5 days. Our delivery time tool shows that number for any two ZIP codes and counts it out on the calendar, skipping Sundays and holidays.
How were these days worked out?
The days come from USPS's own service standard directory for First Class Mail, effective October 1, 2026, which we download from USPS's Service Standards Files API. It gives the days from every 3 digit ZIP area to every other, plus the 5 digit ZIP codes whose letters get a different number. For Indiana we took each of its 789 populated ZIP codes as a starting point and each 3 digit ZIP area of the destination state as an end point, and weighted every pair by the people who live at both ends, using the Census Bureau's 2023 population counts. "Usually" is the range that covers the middle 8 of every 10 letters, and "most often" is the single most common number.
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.
