How the Epstein Files Numbering System Works
Snapshot
The Epstein files do not use one universal numbering system. Records released by the Department of Justice, FBI, Congress, federal courts, local police departments, and civil litigants carry different identifiers.
A single page may display an EFTA number, an FBI case number, an FBI serial number, an evidence item number, and a court docket number. Each identifier serves a different purpose.
The most important distinction is this: an EFTA number identifies a released document or page, while an FBI case number identifies the investigation in which the original record was maintained.
Why the Epstein Files Have So Many Numbers
The public Epstein archive combines records created by multiple agencies over several decades. These records were collected, scanned, processed, redacted, produced to Congress, and released to the public at different times.
Each stage introduced another tracking system.
The principal identifiers include:
- EFTA production numbers
- DOJ data set numbers
- FBI case numbers
- FBI serial numbers
- FBI form numbers
- Evidence item numbers
- Local evidence control numbers
- Congressional production numbers
- Federal court docket numbers
- Exhibit, transcript, and deposition page numbers
These numbers are related only when the document itself connects them.
What Is an EFTA Number?
An identifier such as EFTA00157981 is a production control number commonly called a Bates number.
EFTA refers to the Epstein Files Transparency Act production. The EFTA number gives a released page or document a unique identifier. It does not identify a person, allegation, witness, investigative subject, or category of evidence.
The number alone does not reveal whether the page contains an FBI interview, photograph, email, financial record, court filing, or evidence inventory.
Researchers can locate EFTA records through the Department of Justice Epstein Library and the searchable Epstein Data archive.
EFTA Filenames and Page Numbers
The DOJ generally names a downloadable PDF after its first numbered page.
For example, a PDF named EFTA00157979.pdf may contain the following numbered pages:
EFTA00157979
EFTA00157980
EFTA00157981
EFTA00157982
This means the filename may identify the beginning of a multipage document rather than every page contained inside it.
Researchers should cite the exact EFTA page containing the relevant information whenever possible. They should also preserve the PDF filename because it helps locate the full surrounding document.
Why One Page May Have Two EFTA Numbers
Some Epstein records display more than one EFTA style identifier. A page might contain both:
EFTA00157981
and
EFTA_00005902
This can happen when the same underlying record passes through separate productions, review processes, or congressional releases.
The two identifiers should not automatically be combined into one sequence. They may represent separate productions of the same underlying page.
When both numbers appear, researchers should record both. This can help identify duplicate documents, altered releases, changed redactions, and records reproduced in different collections.
What Are the DOJ Data Sets?
The DOJ Epstein Library separates released material into batches labeled Data Set 1, Data Set 2, Data Set 9, Data Set 12, and similar designations.
A data set number identifies the release batch where the document was published. It does not necessarily identify when the underlying record was created or obtained.
For example, DOJ Data Set 9 contains hundreds of PDFs listed by EFTA filename.
The data set number does not establish:
- The date of the underlying event
- The date the FBI received the evidence
- The investigation that produced the record
- The importance of the document
- The chronological order of the underlying evidence
A document released in Data Set 12 may describe an event that occurred years before a document released in Data Set 2.
What Is an FBI Case Number?
An identifier such as 50D-NY-3027571 is an FBI case or investigative file number.
The NY portion indicates the FBI New York Field Office. The remaining characters belong to the FBI’s internal classification and case tracking system.
Researchers should not assign a precise meaning to 50D without an authoritative FBI classification reference. Internal program designations can change, and the released Epstein documents do not always provide a complete decoding key.
Case number 50D-NY-3027571 appears throughout FBI records concerning Jeffrey Epstein, Ghislaine Maxwell, child sex trafficking allegations, witness interviews, investigative leads, search warrants, and evidence processing.
The official FBI evidence inventory for this case is available through the Department of Justice evidence list.
Researchers can also use the EpsteinWiki search for FBI records to locate related articles and document summaries.
What Is FBI Case Number 50D-NY-3027573?
The identifier 50D-NY-3027573 appears in Epstein related FBI evidence records. It is distinct from 50D-NY-3027571.
Because the final digits are different, researchers should not treat the two identifiers as alternate spellings of the same case number.
The two matters may represent related investigations, linked evidence files, administrative case files, or separate investigative components. The available identifier alone does not establish the precise relationship.
The FBI master case file index preserved as EFTA01731021 contains records associated with the structure and processing of the Epstein investigation. Pages within this production display FBI file numbers, serial numbers, document types, evidence references, and related case information.
The same record is also available through the original released PDF.
Optical character recognition can misread the beginning of the number. Search results may display variations such as:
50D-NY-3027573
050D-NY-3027573
500-NY-3027573
SOD-NY-3027573
The scanned image should be checked before citing the number.
What Is an FBI Serial Number?
An FBI record may display:
50D-NY-3027571 Serial 640
The case number identifies the investigation. The serial number identifies a specific record filed within that investigation.
A serial may correspond to an interview report, incoming lead, memorandum, evidence record, analytical report, electronic communication, or investigative action.
Serial numbers are especially valuable because a single FBI case file can contain hundreds or thousands of records.
A strong citation should preserve the case number and serial number together:
FBI Case 50D-NY-3027571, Serial 640
The citation should then include the relevant EFTA number.
What Is an FD 302?
An FD 302 is an FBI document type. It is not an Epstein case number.
The FBI uses an FD 302 to record information obtained during an interview or another investigative activity. The form is generally prepared by an FBI agent after the interview.
A typical released page may contain:
FD-302
50D-NY-3027571
Serial 640
EFTA00159388
Each marking has a separate function.
| Marking | Meaning |
|---|---|
FD-302 | FBI document type |
50D-NY-3027571 | FBI investigative case file |
Serial 640 | Particular record filed in that case |
EFTA00159388 | Released production page |
An FD 302 should not automatically be described as a transcript. Unless the record states otherwise, it is an agent’s written account of information provided during an interview.
A transcript attempts to reproduce the spoken words. An FD 302 summarizes or memorializes the interview.
What Is an FD 302a?
An FD 302a is commonly used as a continuation page attached to an FD 302.
The first page may identify the interview, participants, date, location, and reporting agents. The FD 302a pages continue the narrative.
Researchers should review every continuation page before summarizing an interview. Important qualifications, denials, agent notes, and additional allegations may appear near the end of the report.
What Are FD 1057 Electronic Communications?
The FBI case index also contains documents identified as FD-1057 Electronic Communication.
An Electronic Communication records information transmitted or documented within the FBI. It may concern investigative assignments, case openings, leads, evidence processing, coordination between field offices, or communications with prosecutors.
An Electronic Communication is different from an FD 302. The FD 302 generally records an interview or investigative information. The Electronic Communication documents an internal investigative action or transmission.
What Are FBI Evidence Item Numbers?
The FBI evidence inventory uses identifiers such as:
1B146
1B145
1D6
1E1
These are evidence or bulky exhibit identifiers maintained within an FBI case.
The released evidence list for 50D-NY-3027571 includes physical objects, photographs, notebooks, computers, storage media, discs, financial documents, intercepted communications, and other seized material.
For example, an evidence item may be classified as general evidence, digital evidence, electronic surveillance material, or another internal evidence category.
The letter and number combination identifies the item. It does not establish what the evidence proves.
What Does Digital Evidence Mean?
An evidence inventory may classify an item as digital even when the original evidence was not created by the FBI.
Digital evidence can include:
- A seized computer
- A mobile telephone
- A hard drive
- A forensic image of a storage device
- A copied compact disc
- A scanned photograph
- Extracted email data
- A digital attachment to an FBI report
- A forensic report generated from another evidence item
Researchers should distinguish the original device from forensic copies and extracted files. Several evidence numbers may refer to different versions of the same underlying data.
What Are Secondary Evidence Numbers?
An FBI evidence description may include additional identifiers such as:
NYC032395
PBPD05-1024
NY-ERF#19236
Submission ID 219407
These identifiers can belong to separate evidence management systems.
NYC may identify an FBI New York evidence control or submission number.
PBPD may identify evidence originally collected or numbered by the Palm Beach Police Department.
NY-ERF may identify a New York evidence or electronic recording facility record.
A submission number may track material transferred to a forensic laboratory, digital analysis unit, or evidence processing facility.
These secondary identifiers can help reconstruct the chain of custody. They may show how an item moved from local police control to FBI possession and later into a federal prosecution file.
What Are DOJ OGR Numbers?
Some later records carry identifiers such as:
DOJ-OGR-00022393
These are production control numbers used on records produced by the Department of Justice in response to congressional requests or oversight activity.
The prefix identifies the production series. The digits identify a document or page within that series.
A DOJ OGR number is separate from an EFTA number, FBI case number, and FBI serial number.
For example, the official transcript of Ghislaine Maxwell’s July 24, 2025 interview is cataloged as DOJ-OGR-00022393.
Researchers should preserve the complete DOJ OGR identifier exactly as printed.
What Are Federal Court Docket Numbers?
Federal court records use another independent numbering system.
Examples include:
United States v. Jeffrey Epstein, 19 Cr. 490
United States v. Ghislaine Maxwell, 20 Cr. 330
In 19 Cr. 490, the number 19 identifies the year the criminal case was opened. Cr. identifies it as a criminal matter. 490 is the court’s assigned case number.
A court filing may also contain an electronic docket entry number such as:
ECF No. 745
The case number identifies the entire court proceeding. The ECF number identifies a particular filing within that case.
Court exhibits, trial transcripts, deposition transcripts, and hearing records may contain their own exhibit and page numbers.
What Are Bates Numbers in Civil Lawsuits?
Civil lawsuits involving Epstein, Maxwell, survivors, financial institutions, executors, employees, and associates produced their own Bates numbered documents.
A civil production might use a prefix based on:
- The party producing the evidence
- The law firm handling the production
- The lawsuit
- The subpoena recipient
- The document collection
These civil Bates numbers are not EFTA numbers. A document may later receive an EFTA number if the DOJ or Congress releases another copy.
When the same document has both numbers, researchers should record both. This can connect a federal release to its earlier appearance in civil litigation.
How to Read a Page With Several Numbers
Suppose a released page contains:
FD-302a
50D-NY-3027571
Serial 640
EFTA00159390
These markings mean:
| Identifier | What it tells the researcher |
|---|---|
FD-302a | This is a continuation page of an FBI investigative report |
50D-NY-3027571 | The page belongs to the New York FBI case file |
Serial 640 | The report was filed under serial number 640 |
EFTA00159390 | This is the public production page number |
None of these identifiers states whether the information is true. That determination requires examining the source, context, corroboration, attachments, surrounding pages, and other evidence.
How to Cite an Epstein File Correctly
A complete EpsteinWiki citation should include every available identifier.
Use this structure:
Document title: FBI interview of a redacted witness
Agency: Federal Bureau of Investigation
Document type: FD 302
FBI case: 50D-NY-3027571
FBI serial: 640
Interview date: August 20, 2021
EFTA pages: EFTA00159388 through EFTA00159393
DOJ filename: EFTA00159388.pdf
Release batch: Applicable DOJ data set
Evidence archive: Direct Epstein Data link
Original source: DOJ or congressional release
This format allows researchers to find the record even if a website changes its navigation, filenames, or database structure.
Common Numbering Mistakes
A lower EFTA number does not necessarily mean that the underlying event occurred earlier.
A data set number does not establish the chronological order of the investigation.
An FD 302 number does not identify the FBI case.
An EFTA number does not identify a witness or investigative subject.
A serial number should not be confused with an evidence item number.
Similar FBI case numbers should not be treated as the same case.
Optical character recognition should not be trusted when the scanned page is unclear.
A person’s appearance in an index, contact list, interview, or evidence description does not establish wrongdoing.
A released allegation is not automatically a verified fact.
Why the Numbering System Matters
The numbering system allows researchers to connect a public page to the larger investigative record.
FBI case numbers and serial numbers help reconstruct the order of investigative activity. Evidence numbers help track physical and digital items. EFTA and DOJ OGR numbers help locate released copies. Court docket numbers connect evidence to judicial proceedings.
Used together, these identifiers can reveal duplicate documents, missing pages, changed redactions, evidence transfers, related investigative files, and records released through more than one channel.
They can also prevent serious reporting errors. A researcher who cites only a screenshot or isolated page may miss the continuation pages, agent notes, document date, case context, or original source.
Key Takeaways
The Epstein files contain several independent numbering systems.
EFTA numbers identify released production pages or documents.
DOJ data set numbers identify release batches.
FBI case numbers identify investigations or related investigative matters.
FBI serial numbers identify records filed within a case.
FD 302 identifies an FBI document type, not a case.
Evidence item numbers identify seized or collected material.
DOJ OGR numbers identify a separate DOJ production series.
Court docket and ECF numbers identify judicial cases and filings.
The strongest citation preserves every identifier printed on the record and links to both the searchable evidence archive and the original government release.
