Estimate an arrival date
Select “Dropping Off Today” to account for the current acceptance cutoff and delivery days. Dates remain estimates unless the selected carrier service explicitly includes a guarantee. For an exact origin and destination, check the ZIP code calculator.
Transit time begins after carrier acceptance. The day a shipment is handed over may not count as the first transit day, especially after a cutoff or on a non-service day.
