GPS System & Address Validation For Shipping

By Adriana Noton

Is it possible to be sure that the package or papers that you sent were delivered to the correct address or business? One way is by using GPS System & Address Validation. This system allows a delivery person to use a device that is like a cell phone to enter a package ID code from the place of delivery. This will both time stamp and location stamp the delivery, effectively validation the delivery of your important goods to the correct recipient.

GPS service allows precision location of the receiving unit. Some units are precise enough that they can be used in land surveying. The unit can give precise location of a delivery truck as it makes the delivery, either in the driveway or the door of the delivery address. The driver of the truck can simply use a scanner to scan a barcode on the package and the delivery time, date and location be sent back to the company headquarters for instant posting on an internet sight confirming delivery.

When expensive equipment is being delivered to a customer by a delivery service, this puts an end to a customer claiming to have never received the equipment. The carrier has GPS documentation that the delivery was made to the correct address. If delivery was made to the wrong address, then the carrier can return to that address to reclaim the equipment that was wrongly delivered.

Another use of this equipment is in the delivery of court papers to an individual. In addition to the manual address verification, the person serving the papers can have GPS address validation that the papers were served to the correct address.

The GPS system was first used experimentally by the US navy in 1960. Since that time several other satellites have been launched. These satellites have been used for airplanes and ships in navigation for years. In more recent times hand held units have become popular and today, many cell phones have included a GPS locator. These much smaller units have made it possible to allow GPS technology to be used for such things as address verification.

If you are considering this system, you do need to take into consideration the United States government has built an error into the GPS system that allows it to be off by as much as 100 meters which is over the length of a football field. This error is included to overcome the possibility of a breach in national security. Thus, although the general area of the delivery and a very accurate time stamp can be given, the exact location may be in error.

GPS address verification is a good idea, but the delivery driver must still use the traditional visual clues to make an accurate delivery. He will still need to look at street signs and house numbers in order to get the package where it should go.

The technology is available to make this system work very precisely. However, there are still a few bugs to work out and one of those bugs is the error that was built into the system by the US government. - 16970
