parcel on hold notice is a notification sent by a carrier, such as USPS, FedEx, or UPS, indicating that a package is being held at a location due to an issue with the delivery, such as incorrect address details, customs clearance problems, or delivery attempt failure. The notice provides instructions on how to retrieve the package or reschedule delivery. Customers receiving a parcel on hold notice should contact the carrier as soon as possible to resolve any issues and ensure prompt delivery.
