Why does a 1958 injury still have a traceable DBA carrier?
A widow walks into your office with a folder. Her husband worked overseas for a military support contractor in the late 1950s. He died decades later from a condition she believes traces back to that work. She wants to file. Your first question is the one that stops most attorneys cold: who insured the employer back then, and is there any way to prove it?
For most claims this old, the assumption is that the trail went cold long ago. Companies merged. Carriers exited. Policy files got pulped. But the assumption is wrong more often than attorneys expect. The DOL kept dated coverage filings going back to 1944, and a large index of those filings now sits in searchable form. That archive spans 78 years of coverage history, which means a card filed in 1958 can still anchor a claim opened today.
This article explains the OWCP coverage card history, why it is the strongest dated coverage evidence available for the Defense Base Act, and how far back it reaches. It does not hand you the carrier for a specific employer. That answer lives inside the data, and pulling it requires running the search. What you get here is the why and the how. You learn why this record type beats every other coverage source. You also learn how a dated filing closes the gap that statutes of limitations, name changes, and carrier insolvencies try to open.
If you have ever told a client that a decades-old claim was probably untraceable, the existence of this archive should change that conversation. Old does not mean dead. It means the evidence is sitting in a filing cabinet that has been digitized and indexed.
What does the OWCP coverage-card archive actually contain?
A coverage card is a deceptively simple document. The DOL used a form, internally tracked as the LS-570, to record one fact for each filing. The card states that this employer carried Defense Base Act insurance with this carrier under this policy, effective on these dates. That is the entire payload. No narrative, no dispute history, just a dated link between an employer and a carrier.
That simplicity is exactly what makes it powerful. Most coverage evidence is inferential. You read a contract, you find a co-occurrence in litigation, you guess from market share. A coverage card is none of those things. It is a primary-source filing that the employer or carrier submitted to the government to prove coverage existed.
The indexed archive in ClaimTrove holds 154,886 of these filing records. They come from two DOL district offices, with 30,631 records from the Boston index and 124,255 from the New York index. Each record carries the employer name as filed, the carrier as filed, and the effective dates. Those three fields are the heart of the OWCP coverage card history that makes DBA carrier dates traceable across the full 78-year span.
One detail matters enormously for old claims. The names on these cards were filed by humans, by hand, across eight decades. The same employer appears under spelling variations, abbreviations, and predecessor entity names. The same carrier shows up under more than 2,000 distinct name strings. We normalized those 2,056-plus carrier name variations down to 724 canonical names grouped into 29 carrier families. Without that normalization, a raw search for one carrier would miss most of its own filings.
That alias problem is not unique to old records. It is the same challenge that drives the hidden carrier families problem, where multiple names mask a single company. A coverage card filed under a long-dead subsidiary name is worthless if your search only knows the modern parent. The archive solves that by mapping the variations back to the family before you ever run the query.
Why is a dated coverage card the strongest evidence you can get?
Defense Base Act coverage disputes almost always come down to two questions. Did coverage exist? And who held it on the date that matters? A coverage card answers both at once, with a date stamp, which no other source does cleanly.
Compare it to the alternatives. Federal contract awards tell you who held the prime contract, but the prime is not always the DBA carrier, and the award rarely names the insurer. Federal contract data reveals a great deal about carrier identification, but it gets you to a strong inference, not a filed fact. Litigation records name the carrier as a party, but only after a dispute already exists, and only for the fraction of claims that reach an administrative law judge.
The coverage card sits above all of them because it is dated and direct. When a carrier argues that it did not cover an employer in a given year, a filed card with effective dates that bracket the injury is hard to wave away. It is not your interpretation of a contract. It is the carrier's own filing.
This matters most in the cases where everything else has gone murky. Consider an employer that changed names three times and got absorbed in a merger. The modern entity may deny any connection to the injury. A dated card filed under the original name, with effective dates covering the work period, reconnects the chain. The same logic helps in disputes over temporal evidence in DBA cases, where the injury date drives everything. If the injury date falls inside a card's effective window, you have placed the right carrier on the right day.
Dated evidence also cuts through the third-party administrator confusion that wrecks so many investigations. A claims adjuster on a letterhead is not necessarily the carrier on the risk. The card names the carrier as filed with the government, which is the entity that actually owed coverage on that date.
How far back does the archive reach, and why does that matter?
The dated records run from 1944 to 2022. That is 78 years of coverage history in one searchable place. This OWCP coverage card history covers the entire modern era of Defense Base Act contracting. It reaches from the post-World War II reconstruction period through the Iraq and Afghanistan drawdowns.
The depth is not a curiosity. It is the whole reason old claims stay viable. Defense Base Act exposure does not always announce itself on the day of the injury. Hearing loss, respiratory disease, and toxic-exposure conditions surface years or decades after the work ends. By the time a claim gets filed, the employer may be gone and the contemporaneous paperwork may be ash. The archive is often the only place the dated coverage link survived.
This is where the archive intersects with the deadline rules. The DBA's one-year filing deadline under Section 913 has real teeth. The two-year occupational-disease exception under Section 913(b)(2) can still keep a late latent-injury claim alive. The point for carrier work is simple. If the law lets a 30-year-old exposure claim proceed, you still have to name the carrier that was on the risk back then. The coverage card is how you do it.
The historical depth also tracks the rhythm of overseas contracting. Coverage filings rise and fall with deployments. A spike in filings for a given theater in a given period tells you which carriers were writing the risk when the work surged. That context turns a single card into a piece of a larger, datable map.
Carrier concentration shifted across the decades too. In the New York index, a handful of carrier families dominate the modern filings. The largest group appears in roughly 29 percent of records, and the next several split most of the rest. That distribution is not static across 78 years. The carriers that wrote DBA risk in the 1950s are not the same names that dominate the 2010s. That is precisely why you cannot reason from today's market backward to an old claim.
How does the coverage card fit into a full carrier investigation?
A coverage card is the strongest single piece of evidence, but a clean investigation rarely rests on one source. The card confirms the carrier and the dates. The surrounding sources confirm the employer identity, the contract, and the theater, so the card is anchored in a story that holds up.
The disciplined approach is to treat the card as the keystone of a layered search. Start by resolving the employer's name and its predecessors, because a card filed under an old entity is invisible to a search built on the modern one. Then pull the dated filing. Then corroborate with contract and litigation data so the timeline is consistent end to end. That sequence mirrors the 5-step DBA carrier investigation workflow, where coverage filings sit at the center as the dated proof the other steps point toward.
The card also disarms the most common carrier defenses. When a carrier claims it never wrote the employer, the filed date range answers the denial. When the adjuster on the file turns out to be a third-party administrator rather than the insurer, the card names the real carrier on the risk. And when the employer has been through a merger, the card filed under the legacy name reconnects the entity to its obligation.
What the card will not do is name itself to you from outside the data. There is no public spreadsheet that lets you type an employer and read off the carrier and the year. The 154,886 records are normalized, deduplicated, and alias-mapped, and that processing is what turns a pile of FOIA images into an answerable question. Running the search against your specific employer and injury date is the step that produces the actual carrier and the actual effective window.
That is the line this archive draws. It proves, for any employer it touches, that the dated coverage link still exists and can be found. It does not pre-publish whose card matches your case. For that, you run the investigation.
What does 78 years of filings reveal about how DBA coverage evolved?
Read the archive across its full span and a story emerges that no single claim can show. The earliest filings reflect a small, concentrated market. Few carriers wrote Defense Base Act risk in the post-war decades, because the volume of overseas government contracting was modest compared to what came later. A handful of names carried most of the exposure.
The picture changes sharply with each major surge in overseas operations. Filings cluster around periods of heavy deployment, and the carrier mix widens and then contracts as insurers enter and exit the market. That churn is not random. Carriers leave DBA when the loss experience turns against them. That dynamic is explained in detail in our look at how DBA insurance premiums work and why carriers leave the market. When a carrier exits, its old filings do not vanish. That is why a defunct insurer can still be the correct answer for an old claim.
The decades-long view also exposes how dangerous it is to reason from the present backward. If you assume that today's dominant carriers were always dominant, you will guess wrong on old claims. The names that wrote the most DBA risk in the 1950s, the 1980s, and the 2010s are largely different. The archive lets you place a claim in the correct era and read the carrier landscape as it actually stood on that date. You do not have to project the current market onto the past.
For attorneys working unusual theaters or unusual periods, this historical depth is the difference between a defensible carrier identification and a hopeful guess. The data is dated, so the answer is dated, and a dated answer is one you can defend in front of a claims examiner or an administrative law judge.
What are the limits of the coverage-card archive?
Honesty about the limits keeps the tool credible. The archive is a FOIA-derived index from two district offices, so it does not contain every coverage filing ever made nationwide. An employer that filed only through other district offices may not appear, and absence from the index is not proof that coverage never existed.
The records also depend on the quality of the original filing. Cards were completed by hand for most of the 78-year span, which means occasional gaps, abbreviations, and ambiguous entries. The normalization process resolves most of the carrier-name chaos, but it cannot invent a date that the filer left blank. When a card's effective dates are incomplete, the card still proves coverage existed, even if it does not perfectly bracket the injury.
This is why the coverage card works best as the keystone of a layered investigation rather than a standalone oracle. Corroborating sources fill the gaps the card leaves. A contract award confirms the employer was active in the theater during the relevant period. Litigation records confirm the carrier was treated as the responsible party. Together they build a timeline that an opponent struggles to unwind.
None of these limits change the core value. For the employers and periods the index covers, a dated card is the single most direct piece of coverage evidence available in the Defense Base Act system. The discipline is to use it for what it proves, corroborate what it leaves open, and never assume that a missing card means a missing claim.
