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 82001 in Wyoming to ZIP 34787 in Florida 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 Wyoming we took each of its 170 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.
