Recommended Use

If a customer requests a required signature upon delivery, use one of the following carriers when available:

  2. FedEx

  3. USPS

  4. GLS US, if enabled

Avoid using Amazon Shipping, DHL eCommerce, GOFO, Passport, TikTok Shipping, or UniUni for orders where signature is required.

Important Note

Once an order has already been fulfilled, shipped, or scanned into a container, the carrier usually cannot be changed. If the customer requires a different carrier with signature required, the order may need to be reshipped if the original shipment is returned or cannot be delivered.
