What you are actually doing
Adding Bates numbers means stamping a unique, sequential identifier on every page of a document set so that any single page can be cited later without ambiguity. You do four things in order: fix the set order, decide the number format, apply the stamp, then proofread against the source. The stamp itself takes a minute. The decisions around it take longer, and they are the part that gets challenged.
Bates numbering is a labeling job, not a legal review. This page covers the labeling sequence. Whether a page is privileged, relevant, or properly produced is a question for the lawyer on the matter, and nothing here changes that.
Step 1: Freeze the set before you number it
A Bates number is only useful if it stays attached to the same page. So settle the page order first.
- Deduplicate. Two copies of the same email with different filenames will get two ranges and confuse everyone reading the index. Merge and de-duplicate before numbering, not after.
- Put the set in the order the index will use. For a production, that is usually chronological by document date, with attachments immediately behind their parent. For a deposition exhibit set, it is exhibit order. Whatever you choose, write it down before you start.
- Merge into a single PDF. Numbering across separate files works, but a single running sequence across one merged file is far harder to get wrong. If your set arrives as many files, merge them first so the sequence has one source of truth.
- Count the pages. You need the total before you pick a starting number, so you can confirm at the end that nothing was skipped.
Do not start stamping while the set is still moving. Renumbering a set that already went out is the kind of error that shows up in a meet-and-confer call.
Step 2: Choose the number format
Three variables: prefix, digits, and separator.
- Prefix. Usually the producing party’s short name, the matter, or a client code. Conventionally uppercase letters, often with a trailing dash or underscore. Pick one and do not vary it mid-set.
- Digits. A fixed width keeps the numbers sortable and makes gaps visible. Six or seven digits is common for a production because it leaves room to grow. If your set is small, fewer digits is fine as long as the width is identical on every page.
- Start value. Most sets start at 000001 or at the next number after the last production. Ask the lawyer which one applies before you stamp; if there was a prior production, continuing the sequence matters.
On the Bates numbering tool, you set the prefix, starting number, digit count, and position, then apply across the whole file in one pass. Because the file never leaves the browser, you can run a test on two pages, look at it, and re-run with different settings without a round trip.
| Decision | Common setting | What breaks if you get it wrong |
|---|---|---|
| Prefix | Party or matter code, uppercase, trailing separator | Conflicting prefixes across a set make the index ambiguous |
| Digit width | Fixed, identical on every page | Variable width breaks sort order and hides skipped pages |
| Start number | 000001, or continue from last production | Restarting mid-matter creates duplicate citations |
| Placement | Bottom right or top right, outside the text block | Stamping over text destroys the page you are identifying |
| Blank pages | Numbered, or explicitly excluded by agreement | Silent gaps look like withheld pages |
| File name vs stamp | Keep original name, track stamp in the index | Renaming to the stamp range loses the source identity |
The last row matters more than people expect. You want to be able to answer “which original file is now ABC-000412” six months from now.
Step 3: Place the stamp so it does not cover content
Placement is a readability decision. A stamp in the bottom right corner clears most letter and legal page layouts, but it will sit on top of footers, page numbers, and signature blocks that already live there.
- Run a test on the pages most likely to collide: a page with a dense footer, a page with a signature block, a landscape page, and a scanned page that fills the frame.
- If the footer is busy, move to the top right, or shift the stamp margin in a few points.
- Rotated and landscape pages are the usual failure. Check that the stamp lands the same way the page reads, not sideways.
- Use a stamp color that survives printing and photocopying in grayscale. Light gray at small size is often invisible on a second-generation copy.
If a page cannot take a stamp without covering text, the usual fix is to add a small amount of white margin rather than stamp on top of the content.
Step 4: Proofread against the source, not against the screen
This is the step people skip. Do it anyway.
- Confirm the page count of the numbered output matches the page count of the input.
- Read the first number and the last number out loud and check them against the total: last minus first plus one should equal the page count.
- Spot check five or six pages spread through the set, including the first page of each merged document.
- Check that every stamp is unique. Duplicates are the error that causes the most downstream pain.
- Open the file at 100 percent zoom on a page with small text and confirm the stamp is legible.
- Keep the unnumbered source file. Always.
If the numbers are right but the order is wrong, fix the order and renumber. Do not patch individual pages by hand; hand-patched sequences are where duplicates come from.
When this does not apply
Bates numbering is a working convention, not a rule that fits every set.
- Single-page documents going to a counterparty for signature usually do not need a stamp. A page identifier adds nothing and can make a plain contract look like a production.
- Court or agency rules that specify a numbering format override everything on this page. If the local rules or a standing order say where and how to number, follow those, not this.
- Native-file productions may not be numbered page by page at all, or may be numbered by a load file instead. Check the production protocol before you stamp anything.
- Sets still under review for privilege or redaction should not be numbered and produced in one go. Numbering implies the set is final.
- Confidentiality and privilege calls are not labeling decisions. If a page’s status is unclear, that page waits for the lawyer. No tool resolves it.
One more boundary: a correct stamp does not make a document admissible, complete, or properly produced. It makes it findable. The lawyer on the matter still has to sign off on what is in the set and what is withheld.
How long it takes
For most sets the stamping itself is a couple of minutes; the set preparation and the proof pass take the rest. The practical measure is: one pass to merge and de-duplicate, one pass to stamp, one pass to proof. If you find yourself on a fourth pass, the set order was not settled before you started.
Use the word counter if you need to confirm a cover index or privilege log entry length matches what the filing format allows, and the date calculator if a production deadline is running against a service date and you need the interval in plain days.
FAQ
Should I number blank pages in a Bates set?
Usually yes, so the sequence has no gaps that look like withheld pages. Some agreements allow skipping them. Confirm the convention for the matter before you decide.
Where do Bates numbers usually go on the page?
Bottom right or top right, outside the body text, same place on every page. Check landscape and rotated pages separately, and keep the stamp legible on a grayscale copy.
Can I add Bates numbers to a document set without uploading it?
Yes, if the tool runs in the browser. On this site the file is processed locally and never sent to a server, so the set stays on your machine.
How many digits should a Bates number have?
Enough digits to cover the whole set plus room for later productions, used at a fixed width on every page. A common choice is six or seven digits starting at 000001, or continuing from the last number already produced.
