What is a lien tape?
A lien tape is the collateral-identity slice of a loan tape: one row per loan carrying the VIN or HIN, the lien status, and the lienholder of record. It is the part of the tape that can be verified against the outside world — not just checked for internal consistency.
The distinction matters because a loan tape — as the industry defines it, "a comprehensive, data-rich spreadsheet or electronic file used by financial institutions, lenders, and investors to track and analyze a portfolio of loans" (Kolena) — is reviewed as data, and everything on it comes from the seller. The lien tape is different in kind: its columns make claims about the physical world (this vehicle exists, this lien is held, nobody else has it) that a buyer can test independently.
Loan tape vs. lien tape
| Column | Tape | Verifiable against |
|---|---|---|
| Balance, rate, term | Loan tape | The credit file (internal) |
| FICO, DTI, delinquency | Loan tape | The credit file (internal) |
| VIN / HIN | Lien tape | Decode validity; duplicates inside the pool |
| Lien status | Lien tape | The seller's monitored book |
| Lienholder of record | Lien tape | The cross-lender network |
How to Sweep a lien tape before you buy
Run the dedupe on the tape itself first — a spreadsheet-level check that no VIN or HIN appears twice inside the pool. Then a Portfolio Sweep runs the two checks the tape can't answer on its own, inside a ShieldVIN Deal Room:
| Check | Question it answers |
|---|---|
| 1 · Cross-book check | Is any identifier on the tape also claimed on the other party's book? When the seller is the member who opened the room, their side is their live monitored book — so this is a check against the liens they actually hold today. |
| 2 · Network check | Is any identifier claimed by another institution in the clearinghouse — including lienholders outside the deal, who are alerted on a conflict? |
On a match, each party sees full detail on its own assets only; the other side's exposure arrives as a count, never as their book. The seller doesn't need to be a ShieldVIN member to participate.
How this shows up in underwriting a purchase
Price the pool on the loan tape; close on the lien tape. A tape that fails the dedupe or the network check isn't necessarily a dead deal — it's a precise list of identifiers to resolve, carve out, or reprice before funds move. The buyers who get hurt are the ones who never asked the question.
Common questions
Is a lien tape a standard deliverable in a loan sale?
The columns are — every loan tape carries VINs and lien fields. Treating them as a distinct, independently-verifiable artifact is the discipline this page is naming.
What if the seller won't share VINs pre-close?
The Deal Room is built for exactly that concern: neither side browses the other's book, and a non-member seller uploads as a guest into a room both parties entered by consent. Matches reveal only assets each side already claims.
Does this work for boats, RVs, and powersports pools?
Yes — the same checks run on 12-character HINs as on 17-character VINs. If it has a VIN or HIN, it can be swept.
