The Basics

What is Bates numbering
and where did it come from?

Bates numbering is a method of placing a unique sequential identifier on every page of every document in a litigation matter. The name comes from the Bates Automatic Numbering Machine — a mechanical stamp invented by the Bates Manufacturing Company in the late 19th century — which attorneys used to physically stamp numbers onto paper documents during discovery.

Today, Bates numbers are applied digitally to PDFs, but the purpose is the same: give every page in every document a single, unambiguous reference number. When an attorney says "please turn to page DEF003247," everyone in the room — opposing counsel, the judge, the witness, the court reporter — can find exactly the same page instantly.

For paralegals, Bates numbering is one of the core production management tasks. You are responsible for ensuring that every document produced in discovery has unique, correctly formatted Bates numbers — and that those numbers are tracked and logged in a production index that the firm can reference throughout the life of the case.

When You Need Bates Numbers

The four contexts where
Bates numbering is used

Bates numbers appear throughout litigation — from the first document request to trial. Knowing when each context applies will help you plan your production correctly.

📂

Discovery Productions

The primary context. When a party responds to document requests (RFPs), produced documents are Bates-numbered sequentially. Each production batch continues from where the last left off.

📝

Deposition Exhibits

Exhibits used during depositions are Bates-numbered so that attorneys, witnesses, and the court reporter can reference them precisely. Deposition transcripts cite exhibits by Bates range.

⚖️

Trial Exhibits

Trial exhibits may use a separate exhibit numbering scheme (P-1, D-1) but often also carry their original Bates numbers for cross-referencing to the discovery record.

🗂️

Internal File Management

Many firms apply Bates numbers to all significant documents in a file — even before litigation begins — for internal reference, expert witness packets, and settlement demand packages.

FRCP Rule 34(b)(2)(E): Documents must be produced as kept in the ordinary course of business, or organized and labeled to correspond to categories in the request. For ESI, Rule 34(b)(2)(E)(ii) requires production in a reasonably usable form. While Bates numbering is not explicitly named in the Federal Rules, it is the universal standard for identifying produced documents — and is required by many local rules and judge standing orders. Always check your district's local rules and any ESI protocol agreed to by the parties.
Naming Conventions

Prefix, digit length, and
formatting standards

The format of a Bates number must be consistent throughout an entire case. Here are the conventions most commonly used in federal and state litigation.

Element Standard Practice Examples & Notes
Prefix 3–6 uppercase characters identifying the producer PLTF, DEF, ABC, SMITH, ACME01 — avoid spaces or special characters; use only letters and numbers
Separator No separator (most common) or underscore DEF003247 (preferred) or DEF_003247 — never use spaces or hyphens in the number itself
Digit length 6 digits for most cases; 8 for large productions DEF000001 through DEF999999 (6-digit); DEF00000001 (8-digit) — must be consistent throughout the production
Multi-defendant Unique prefix per party DEF1000001, DEF2000001 — or company abbreviations: FORD000001, GOOG000001
Multi-matter Add matter identifier to prefix 2024CV123-DEF000001 — useful when a firm has multiple matters with the same parties
Continuation Next batch starts where last batch ended +1 Production 1 ends at DEF003247; Production 2 starts at DEF003248 — never reuse or skip numbers
Position Lower right or lower left corner Bottom corners are standard; some courts or firms use top right — check any ESI protocol
Production Workflow

How to run a discovery
production as a paralegal

A well-run production protects the client and the firm. Follow these steps for every production batch — whether it is 50 documents or 50,000.

1

Collect and review documents

Gather responsive documents from the client, custodians, and any document management system. Run a privilege review with the supervising attorney — flag attorney-client privileged documents and work product for withholding. Documents to be withheld go on the privilege log; the rest proceed to production.

2

Determine your starting Bates number

Check your production log (the spreadsheet tracking all prior productions) for the highest Bates number previously used in this matter. Your first document in this batch gets the next sequential number. If this is the first production, start at 000001.

3

Stamp each document

Using the RapidTools Bates Stamp tool (or your firm's preferred software), apply Bates numbers to each PDF. Set your prefix, digit length, and starting number. The tool numbers each page sequentially. If you have 10 documents totaling 47 pages, the first document's pages get numbers 1–12 (for example), the second gets 13–22, and so on — continuously across all documents.

4

Update your production log

Record each document in your production log: production batch name, original filename, document date if known, author/recipient, document type, starting Bates number, ending Bates number, and total pages. This log is essential for privilege log cross-referencing and for quickly locating documents during depositions or hearings.

5

Prepare the production package

Compile the Bates-stamped PDFs, a cover letter (referencing the RFP numbers being responded to and listing any objections), and any required load file for e-discovery platforms. Most productions in federal court are delivered by secure file transfer or encrypted thumb drive — confirm delivery method with the supervising attorney and the ESI protocol.

6

File a certificate of service

Confirm that production was delivered to all counsel of record and file a Certificate of Service (or log the service in your case management system). Record the production date — discovery deadlines run from when documents are produced, not when they were requested.

Common Paralegal Mistakes

Bates numbering errors to
avoid at all costs

Bates numbering mistakes can create serious problems in litigation — from confusion at depositions to sanctions motions from opposing counsel. These are the most common errors paralegals make.

Restarting at 1 for each document

Treating each document as having its own numbering series (Doc1 page 1, Doc2 page 1) defeats the purpose of Bates numbering — any reference to "page 1" is ambiguous.

✓ Fix: Numbers must run continuously across all documents in a production batch and across all batches in a matter.

Inconsistent digit length

Mixing DEF001 and DEF0001 in the same matter causes sorting errors and looks unprofessional. Sorting algorithms treat these as different lengths.

✓ Fix: Decide on digit length (6 or 8) at the start of the matter and never deviate.

Duplicate Bates numbers

If two pages share the same Bates number, every reference to that number in briefs, transcripts, and orders is ambiguous. This can require re-production with corrected numbers.

✓ Fix: Always check the production log before stamping. Never estimate starting numbers from memory.

Gaps in the sequence

Gaps raise a presumption that documents were withheld without being logged. Opposing counsel will notice — and may file a motion to compel explaining the gap.

✓ Fix: If a document is withheld, assign it a Bates range and note it on the privilege log with that range.

No production log

Without a log, you cannot quickly find a document by Bates number, verify what was produced in which batch, or accurately prepare a privilege log.

✓ Fix: Create and maintain a production spreadsheet from the first production in every matter — even small cases.

Stamping privileged documents

If a privileged document gets Bates-stamped and accidentally produced, you have potentially waived privilege. Clawback provisions in ESI orders help, but it is better to avoid the problem.

✓ Fix: Complete privilege review and attorney sign-off before stamping any document for production.
FAQ

Common questions about
Bates numbering in litigation

Answers to the questions paralegals and law students most frequently ask about Bates numbering.

Bates numbering is a system of adding unique sequential identifiers to every page of every document produced in litigation. A Bates number typically consists of a prefix (often an abbreviation of the party or case) followed by a zero-padded sequential number — for example, DEF000001. This allows attorneys, paralegals, and courts to reference any specific page in any document by a single, unambiguous identifier during depositions, hearings, and briefs.
FRCP Rule 34(b)(2)(E) requires that documents be produced either as they are kept in the ordinary course of business, or organized and labeled to correspond to categories in the request. For ESI (electronically stored information), FRCP Rule 34(b)(2)(E)(ii) requires production in a form in which it is ordinarily maintained or in a reasonably usable form. While Bates numbering is not explicitly mandated by the Federal Rules, it is the universal standard practice in federal litigation and required by many local district rules and individual judge standing orders.
The prefix identifies the producing party and often the case or matter. Common formats: PLTF (plaintiff), DEF (defendant), company name abbreviation (e.g., ABC for ABC Corporation), or a matter-specific code. For multi-defendant cases, use unique prefixes for each defendant (DEF1, DEF2 or company abbreviations). The prefix should be short (3–6 characters), consistent across all productions in the matter, and agreed upon in the ESI protocol or stipulated order if one exists.
Six to eight digits is standard practice. Six digits (DEF000001) handles productions up to 999,999 pages — sufficient for most litigation. Eight digits (DEF00000001) is used for large commercial cases or multi-million-page productions. The digit count must be consistent throughout a production — once you choose a digit length, all Bates numbers in that production must use the same padding. If your production will exceed the capacity of your chosen digit count, you must re-number the entire production.
Bates numbers must be sequential and non-repeating across all productions in a matter. If your first production ends at DEF003247, your second production must start at DEF003248. Maintain a Bates log (a spreadsheet tracking production batch, document name, starting Bates, and ending Bates number) to ensure no gaps or overlaps. Many paralegals maintain this log in Excel or the firm's case management system. If you use RapidTools' Bates stamp tool, enter the starting number for each production batch manually before stamping.
Yes. The RapidTools Bates stamp tool runs entirely in your browser — client documents are never uploaded to any server. You can set your prefix, starting number, digit padding, and position (top/bottom, left/center/right). The tool processes PDFs of any size. For multi-document productions, stamp each document separately with the correct starting number (carried over from the previous document's ending number), then merge using the free PDF Merge tool if needed.
A privilege log identifies documents withheld from production on grounds of attorney-client privilege or work product doctrine. Under FRCP Rule 26(b)(5), the log must describe the nature of the withheld documents in sufficient detail to enable the other party to assess the privilege claim — without revealing the privileged content itself. Each entry in the privilege log should include the document's Bates range (if a placeholder was assigned) or a unique identifier, the date, author, recipients, document type, subject matter, and the privilege asserted.
