DO DATA DIFFERENT. GET DIFFERENT RESULTS.

Path2Linkage

HEM-first identity resolution, built on real transactions.

Part of the Path2Real product family, alongside Path2RealBuyers and Path2RealDonors.
Most identity graphs are stitched together from whatever signal is available — cookies, device IDs, modeled matches. Path2Linkage starts somewhere more solid: hashed emails (HEMs) tied directly to real, verified transactions and CASS-certified postal addresses. As we put it internally: “Path2Linkage doesn’t replace your ID graph — we add resolution to make it more powerful.”

Why it matters: a HEM sitting in your identity graph today may have gone stale years ago. Path2Linkage adds a recency signal that shows which HEMs are still actively in use — not just which ones exist.

WITH PATH2LINKAGE

  • Resolve more of your identity graph: incremental HEMs your graph doesn’t have yet, verified against real transactions.
  • Round out digital-only data: match a HEM back to a verified household postal address — email-to-postal reverse append.
  • See which identities are still alive: a recency signal that separates active HEMs from stale ones.
  • Raise match rates on every file you process: cleaner data, more accurate matching, more reliable workflows.
Delivered monthly via SFTP on a rolling 24-month window. One row per hashed email (MD5, SHA-1, SHA-2), tied to an individual’s name and postal address.

EXAMPLE USE CASES

Identity graph resolution. Append incremental HEMs your graph is missing, plus a recency signal for which identities are still active.
Match rate improvement. Data service providers use the file to raise match rates on the lists and campaign files they process.
Advertising. Target advertising on display and social media networks, plus search, mobile, CTV, OTT, and email.
Email-to-postal reverse append. Match a HEM back to a verified household postal address to round out digital-only data.
Suppression & verification. Confirm the validity of email or postal addresses, plus identifiers like device ID, cookies, and MAIDs.
Sub-licensing. Sublicense or distribute the data as a core component of an integrated identity solution, under equivalent terms.

What’s in the file

Composition and verified scale, straight from the file layout.

FILE COMPOSITION

Name — first, middle, last
Postal address, incl. Delivery Point Barcode (DPBC)
Hashed email — MD5, SHA-1, and SHA-2
All-time hashed emails per individual
CASS-certified addressing

VERIFIED SCALE

583M+ hashed-email records
190M+ unique HEM-to-postal matches
Updated monthly, rolling 24-month window
Delivered via SFTP
Three hash rows per unique HEM-to-postal match (MD5, SHA-1, SHA-2) is why record count and unique-match count differ

PRICING Preferred as an annual subscription, or a base fee plus usage — priced on the incremental value you get.

1 duck

Every HEM traces back to a real transaction.

Not a cookie, not a device graph guess, not an inference. That is the difference between ground truth and hearsay — and it is the whole reason Path2Linkage resolves what other identity data can’t.
