Frequently asked questions
How long does it take to ship my order?
Most orders are processed and shipped within 1–3 business days, or refer to the product page order handle time. Delivery typically takes 3–15 business days for standard shipping, depending on your location.
How do I track my order?
Once your order is shipped, you will receive a confirmation email with your tracking number. Use it to track your package on our website or the carrier's website.
My tracking number isn't working. What should I do?
Tracking information may take 24–48 hours to update after shipment. If it still doesn't work after 48 hours, please contact us at leadleds@untsmart.com.
Can I change my shipping address after placing an order?
