IN-KCS Mail™ - Endicia Label Server

With IN-KCS Mail™ ELS, ALL of your domestic addresses will be validated in Clippership, AKA BluJay Parcel, just prior to rating the package. Suggested address corrections may be displayed to the end user and updated in Clippership as needed. Addresses deemed as Residential will be automatically flagged as such to enable accurate rating, regardless of the carrier!

When ready, simply press the record package button to produce a fully compliant USPS carrier label which is then sent to your existing label printers and paper stock.

Our IN-KCS Mail Platinum Endicia account type provides our customers with Commercial Pricing and Priority Mail Cubic rates for qualifying packages weighing up to 20 lbs providing even deeper discounts! Contact us today to find out how much you can save with rate shopping!

International, APO/FPO/DPO & U.S. Territories

International shippers will also benefit from automated customs documents. IN-KCS Mail will send your PS2976 & 2976A Customs Declaration and Dispatch Notes directly to your existing label printers and/or your 8.5" x 11" document printers on your existing paper and label stock. Since these documents are already signed and date-round-stamped, simply hand the package over to your Postal carrier or drop it into your nearest Postal drop-box.

Parcel Consolidators add Deep Discounts

Parcel Consolidators work together with the USPS and other couriers to offer discounted shipping rates to both Domestic & International destinations. IN-KCS Mail enables users to combine all the standard USPS services already offered by IN-KCS Mail, with up to two parcel consolidators - one consolidator for Domestic and another for International shipments.
