eInduction
eInduction is a USPS process that checks the payment and preparation of commercial mail containers by scanning their barcodes against the mailer's electronic documentation.PostalPro: eInduction“verify payment and preparation of commercial mail containers”USPS original It handles drop shipments and expedited plant load mailings without paper PS Forms 8125 and 8017.Guide to eInductionpage 6“eliminates the need for paper PS Forms 8125 and 8017 and manual reconciliation at the entry facility”USPS original
What it is
eInduction is a way of entering mail at USPS facilities that works at the container level.Guide to eInductionpage 11“eInduction is at the container level – not at the piece level.”USPS original Full-Service mailers and the providers that prepare their mail use it.PostalPro: eInduction“Mailers and MSPs participating in Full-Service.”USPS original USPS deployed it in October 2013.PostalPro: eInduction“The eInduction program was successfully deployed in October 2013”USPS original
It replaces paper checks at the dock with data, so clerks no longer reconcile containers by hand against paper forms.Guide to eInductionpage 6“Increased use of data through eInduction speeds mail induction of containers. It enables quicker appointment processing in the Facility Access Shipment Tracking (FAST) online system, it eliminates the need for clerks to manually reconcile containers against paper documentation (PS Forms 8125 and 8017), and it provides 24/7 appointment resolution.”USPS original FAST, the USPS system for drop shipment appointments, also resolves appointments around the clock.Guide to eInductionpage 6“it provides 24/7 appointment resolution.”USPS original
eInduction supports drop shipping, where mailers earn discounts by entering mail closer to its destination.Guide to eInductionpage 7“Mailers receive destination entry discounts when they bypass mail processing by drop-shipping mailings closer to the”USPS original It is a requirement for Seamless Acceptance mailers that create drop shipments.Guide to eInductionpage 7“eInduction is a requirement to be a Seamless Detached Mail Unit (DMU) mailer and BMEU Seamless mailers that create drop shipments.”USPS original
How it works
The mailer's preparation is the same at every kind of drop site.Guide to eInductionpage 7“From a mailer perspective, the mail preparation process is the same, regardless of drop ship location”USPS original What differs is the scanner: a site either has a Surface Visibility scanner or uses an IMDAS scanner instead.Guide to eInductionpage 7“whether the drop location has a Surface Visibility Scanner (SV Site) or”USPS original Surface Visibility sites check containers as they arrive.Guide to eInductionpage 9“When the containers arrive at a Postal facility: a. With SV capability, SV scanners interact with the 45-day unique Intelligent Mail container barcodes on the containers to verify payment status and induction location.”USPS original At other sites, checks happen after induction.Guide to eInductionpage 9“No validations take place at the entry point at Non-SV locations. … For containers inducted at a Non-SV facility, all verifications occur post-induction.”USPS original
The normal case, from preparation to reports.
- The mailer confirms its rate, processing categories, container types and facility types are eligible.Guide to eInductionpage 8“Ensure mailings are eligible for eInduction based on eligible rate, processing categories, container types, and facility types.”USPS original
- The mailer puts a unique IMcb, the Intelligent Mail container barcode, on each container.Guide to eInductionpage 8“Prepare mail with Intelligent Mail Container barcodes (IMcb) that are unique and not reused for at least 45”USPS original
- The mailer books a FAST appointment for a processing facility or hub.Guide to eInductionpage 8“Mailers dropping at both SV and non-SV network USPS Processing Facilities and Hubs must schedule”USPS original
- The mailer flags its containers as eInduction in the eDoc and uploads it to PostalOne!.Guide to eInductionpage 9“Mailers must flag (identify) their containers as eInduction in Mail.dat, Mail.XML or Postal Wizard (PW) and”USPS original
- The eInduction module in PostalOne! creates container records and sends them to FAST and Surface Visibility.Guide to eInductionpage 9“The eInduction module in PostalOne! creates container records and automatically transmits these records to”USPS original
- At a Surface Visibility site, scanners read each IMcb to check payment and induction location.Guide to eInductionpage 9“on the containers to verify payment status and induction location.”USPS original
- At other sites, USPS employees scan each IMcb with an IMDAS scanner.Guide to eInductionpage 9“the Postal Service acceptance employees use an IMDAS scanner”USPS original
- After induction, USPS systems check for duplicate barcodes and the claimed entry discount.Guide to eInductionpage 9“Additional validations detect the presence of duplicate barcodes and measure whether”USPS original
- Reports tell the mailer about payment, induction and delivery of each container.Guide to eInductionpage 9“real-time reporting informs the mailer through payment, induction, and”USPS original
Delivery units take eInduction containers without appointments.Guide to eInductionpage 9“destination delivery units (DDUs) do not schedule appointments.”USPS original

Flagging containers in the eDoc
An eDoc is the mailing's postage statements and supporting paperwork, sent electronically instead of on paper.Guide to eInductionpage 12“eDoc consists of postage statements and supporting paperwork that are submitted electronically”USPS original The mailer marks each eInduction container in it with a Y in the eInduction Indicator field.Guide to eInductionpage 11“mailers must set the eInduction Indicator field on the”USPS original

Onboarding
A mailer that meets the requirements asks to join through the FAST Helpdesk.Guide to eInductionpage 16“requesting to participate in eInduction via the FAST Helpdesk (1.877.569.6614 or FAST@usps.gov)”USPS original The mailer names the Customer Registration IDs, the numbers for each business location, that will send eInduction mailings.Guide to eInductionpage 16“a unique number that identifies a specific business location that will be involved in eInduction”USPS original Onboarding takes 2 to 3 weeks on average and 4 weeks at most.Guide to eInductionpage 16“of 2-3 weeks, with a maximum of 4 weeks, from initiation to mailer activation.”USPS original
