Track an Order

When your order leaves us, we email a shipping notification with your carrier tracking number. Enter that number below to see its status on the carrier's site.

Look up a tracking number

Orders ship by UPS, so your tracking number starts with 1Z. Orders shipped before October 7, 2026 may have a USPS number instead; this lookup opens either carrier.

No tracking email yet?

Tracking is sent when your order is dispatched, not when it is placed. Items badged “Ships Same Day” are dispatched the same business day when ordered Monday–Friday before 3:00 PM Pacific; items badged “Ships in 7 Business Days” are dispatched within 7 business days. Local delivery orders are hand-delivered and do not carry a carrier tracking number.
