Postcom.org--The United States Postal Service (USPS) has approved Window Book, Inc.'s Postal Package Partner Shipping with integrated (USPS®) Global Shipping Solution (GSS) for streamlined shipping of International Priority Mail and other classes of International Mail. PPP is the mailing and shipping industry's leading postal shipping and manifest software that uses permit imprint to pay postage. Due to a multi-agency Federal mandate from U.S. security and financial agencies, as of April 1st, 2012 the USPS is required to collect electronic customs data for packages accepted for shipment to international destinations. Electronic customs data will no longer be an option, but becomes one of the basic requirements for international USPS shipping. The USPS needs to have the data in hand and available in electronic form to provide Federal agencies during the same timeframe they have the packages in their possession so they can stop/divert a package as needed before it leaves the USA. Postal Package Partner offers business mailers efficient and cost-effective shipping solutions which meet their individual needs, and allows them to benefit from many postal services. Currently, PPP supports various USPS services, including Commercial Rates for Domestic and International Priority Mail and Express Mail, First-Class Mail®, Priority Mail®, Express Mail®, Parcel Post®, Media Mail®, Library Mail, Bound Printed Matter, Express Mail and Priority Mail Open and Distribute (PMOD). PPP's latest integration with the USPS GSS will definitely increase its application functionality as well as enhance its integration with the Postal Service.
