The spreadsheet problem

Essential compliance data doesn’t belong in a spreadsheet.

  • State & federal inspectors expect evidence of review on every Authorized Trading Partner (ATP) confirmation.
  • Most health systems still track partners in emails and spreadsheets that go stale the moment a license changes.
  • Checks can’t be performed in a vacuum — ownership, locations, licenses, contacts, borrow/loan and drop shipments all have to line up.
  • When the data isn’t signed, you’re trusting a copy-paste. Is your spreadsheet dusty?

How it works

Three workflows, one source of truth

The Address Book is the easy button for trading partners. Every workflow is backed by OCI-compliant digital credentials — with manual fallbacks when you need them.

01

Manage your own data

A web dashboard for the corporate master data, facility addresses, state licenses, GS1 GLNs and contacts that are otherwise scattered across repositories.

02

Manage your trading partners

Populate your book from a directory or by hand. Already-credentialed partners arrive with validated data you can simply supplement.

03

Request information

Ask a partner to review their record. Their named contact gets a prefilled form, reviews and revises, and signs it back — no chasing.

Signed, not self-asserted

Proof of identity and ATP status on every transaction

LedgerDomain seeds the directory from publicly available data to make onboarding fast — but only a partner can sign their own messages. Each one “stamps” every transaction with a tamper-evident proof, using strong cryptography built on open industry standards.

  • OCI-compliant digital credentials
  • Interoperable across the Verification Router Service (VRS)
  • Covers ATP confirmation, exceptions & suspect-product investigations
  • Independently verifiable — no central authority to trust

What a real Address Book requires

An ATP address book is only as trustworthy as the data behind it. Before you rely on any system, hold it to these six requirements.

Partner-signed records

Every record is cryptographically signed by the partner who owns it, so you always know who stands behind the data rather than trusting a hand-keyed entry.

ATP status tracked over time

Authorized Trading Partner status is monitored continuously as licenses and credentials change, so a confirmation reflects the partner today, not the day someone last touched a cell.

Coverage for uncredentialed partners

Indirect partners who don’t hold a credential are still validated through the Legisym License Verify™ integration, which confirms licensure across state boards and federal agencies in real time.

Borrow / loan & drop-shipment relationships

The record models direct, drop-shipment, and emergency pharmacy borrow/loan relationships — the shipment paths DSCSA actually runs on.

Information-request workflows

Ask a partner to review and re-sign their record; their named contact receives a prefilled form and signs it back, with no email chasing on your side.

A six-year audit trail

Every confirmation, request, and change is retained as tamper-evident evidence for the six-year window DSCSA expects inspectors to be able to review.

Customer proof · Wholesaler

Morris & Dickson published its data in the Address Book — in a matter of hours.

A top national wholesaler, M&D self-published its credentialed master data so customers and suppliers could keep shipping and receiving product with less administrative burden. Four trading partners — three health systems and a manufacturer — instantly added M&D’s signed data to their own address books.

Credential-signed master data makes it easy for trading partners to continue receiving and shipping product — and reduces administrative burden.
