A major benefit of this 3 digit STC is that US postal service can reduce the number of barcodes on a package or mail piece. One of the best tracking site is usps tracking To track Package Delivery & Reach Destination and it is based on real time postal service locations (local post offices).

If you have made COD, Certified Mai, Insured or Registered Mail, you know that each of these services uses a distinct barcode. USPS tracking  can be represented by a single barcode, which also provides the tracking function. 

USPS tracking special services are often indicated by colored labels. These colors help the USPS tracking operational staff identify pieces that need special handling. In the future, you will surely see these colors disappear when the IMPb effect becomes more pronounced within USPS tracking operations. In the transition period, USPS is the creation of colored labels covering the various special services but without special barcodes.  Eksempel på et registreret mail-mærke med and ny rød label 200N, sum svarer til den gamle label 200, sum bærer sin egen strekode. This was created using DAZzle with the Label 200N added as an image and then printed on a color printer.

Eliminating multiple barcodes on packets reduce confusion in USPS operational flow and accelerate USPS tracking package preparation by shipper. Perhaps more importantly, the usps tracking shipment does not have to keep track of each package for different identifying numbers - each often reported via different data streams.

The rewording reflects the USPS tracking ongoing commitment to provide better package visibility during the delivery cycle. Once the delivery confirmation started around 2000, you have just one scan that indicates the delivery date. Now, du vil typisk se about 10 scan events for and given usps-pakke, så "tracking" there and more præcis beskrivelse hvad den barcode gør. The nye bannere about drafts indikerer hvilke tjenester der er nvdvige for delivery, og the forsendelsesvirksomhed vil også være opmærksom ved scanning af. The usps tracking service scanner will tell him exactly what actions are needed.

The carrier route is the number in the small rectangular box. This is used to sort packages at the destination post office just before the carrier goes out to make his or her deliveries. Each usps tracking post office divides the routes that they service by numbers.
