        2. Why is there no movement on my tracking number?

        Once your order has been processed and shipped, you will receive an automated message with your order's tracking information. Please note that due to the high volume of packages shipped daily, it may take 24-48 hours (72hrs for items shipped via UPS Mail Innovations) for the carriers to update their system.

Rest assured that your shipment is still moving even though no new tracking scans may appear for a while.

        - We at YesComUSA care about the security and privacy of our customers. We use one most advanced encrypted software and are very diligent about protecting your privacy and personal information.

        6. My package is being held at UPS Access-Point. What do I do now?

        -In some cases, packages may be held at a UPS Access-Point due to the following reasons.

If packages are not picked up on the 5th day, UPS will ship the item back to the sender.
