## What is a delivery lead time?

[Delivery lead times](/core-api-reference/delivery_lead_times.md) provide customers with an estimated time of arrival range — for example, a shipment arriving in 2-5 days. Since a market can have many stock locations and shipping method options, different delivery estimates can be shown for each available delivery option.
