What is ISBN?
ISBN (International Standard Book Number) is a system of numerical identification for books, pamphlets, educational kits, microforms, CD-ROM and braille publications.
By assigning a unique ten-digit number to each published title, the system provides that title with its own, unduplicated, internationally recognized "identity." Publishers, booksellers, libraries and other participants in the book industry use ISBN to identify publications in order to expedite their handling and retrieval. ISBN ensures that ordering, inventory control and accounting are executed more efficiently.
The ISBN number usually is on the back cover or the copyright page. [top]

Package Tracking Related [top]
USPS Package Tracking

Which services provide delivery information?
Delivery Confirmation service, Signature Confirmation service, Certified Mail and Registered Mail provide delivery information. [top]

What does Delivery information provide?
Delivery status information provides the date and time of delivery or attempted delivery.
  • It does not include tracking of the package enroute.
  • If there is no scan event information available for your mailing, you will receive a message similar to one of the following:
    • "No information is available for this item. Please contact the sender."
    • "There is no record of that item. If it was mailed recently, information may not yet be available. Please try again later."
  • This does not mean that the item has not been mailed. It just means that it has not been scanned in as having been delivered.
    • If you are the addressee, you should contact the sender for more information regarding when it was mailed.
    • If you are the sender, you can check back at a later time (status information is usually updated every evening).

    When will Delivery Information be Available?
    Information is generally available on the evening of the date of delivery or attempted delivery, when the mailperson returns from their route. [top]

    How long is Delivery information available?
    We keep records for the amount of time specified below before they are purged out of our system. Information for Delivery Confirmation, Signature Confirmation, Certified and Registered mail is moved to off-line (archive) storage after 60 days. Information for Express Mail, Global Express Mail and Global Express Guarantee is moved to off-line storage after 90 days. Full event information can be restored upon request.
  • Delivery Confirmation service - 6 months.
  • Signature Confirmation service - 1 year.
  • Express Mail, Certified Mail and Registered Mail - 2 years. [top]

    What if there is no delivery information available when I call the toll-free number or visit the Web site?
    If there is no delivery or delivery related information (such as attempted or forwarded) available when you call 1-800-222-1811 or inquire on the website, we will provide a response of 'no record available.' This does not mean the item is not in the mail system. If the item was mailed recently, it means that no scans have been made or recorded at the time of your inquiry. Delivery information, if available, is updated nightly. Please call or visit the website at a later time.

    Additional information:
  • We can not verify the delivery status of an item without the number from the mailing label or receipt.
  • Insured mailis NOT a trackable service (nor is confirmation of delivery of insured mail available without purchasing the Delivery or Signature Confirmation service).
  • Electronic rate Delivery Confirmation (including Click-N-Ship) may (but is not required to) include the date and time of when it was picked up or accepted for shipment.
  • Retail rate Delivery Confirmation that is brought into the Post Office for mailing will include an acceptance scan.
  • Regular mail (such as Priority Mail or Parcel Post items) can NOT be tracked or verified as to delivery status unless an extra service was purchased at time of mailing.
  • The following services provide tracking information as the item is enroute: Express Mail, Global Express Guaranteed and Global Express Mail. [top]

    What International services can be tracked online?
    Tracking information provides the sender with online details of the item as it is enroute to its destination. Express Mail®, Global Express Guaranteed® and Global Express Mail™ (depending on destination country) are the only services that provide tracking and they must be purchased when the item is mailed.

  • Express Mail numbers typically begin with two letters followed by nine numbers and the letters "US" [ Note: "E" is currently the most common initial letter ], located in the upper right-hand corner, below the barcode. An example might be: EA 000 000 000 US
  • Global Express (Outbound) numbers typically begin with two letters ("E" followed by another letter) followed by nine numbers and the letters "US", located in the upper right-hand corner, below the barcode. For example: EA 000 000 000 US
  • Global Express (Inbound) numbers typically begin with two letters ("E" followed by any other letter) followed by nine numbers and two more letters indicating country of origin, located in the upper right-hand corner, below the barcode. For example: EA 000 000 000 HK
  • Global Express Guaranteed numbers usually have ten digits (no letters), located on the lower right-hand side of the receipt. For example: 82 000 000 00

    Note: Entering the customs barcode number for services such as Global Airmail Parcel and Global Priority Mail may produce tracking events in Track and Confirm. However, if you are interested in tracking your package internationally you should purchase either Global Express Guaranteed or Global Express Mail services. [top]
