PDF Bates Numbering
Add sequential document-control numbers with a custom prefix and position
PDF Bates Numbering — what it does
Stamp sequential document-control numbers onto every page of a PDF, with a custom prefix, a starting number, zero padding and adjustable text size. Bates numbering is the standard in legal discovery and records management because it gives every single page a unique, citable identifier.
When this tool helps
- Preparing document sets for legal discovery, where every page must be individually referenced.
- Numbering a records submission so a regulator or auditor can cite specific pages.
- Controlling a large document bundle where page-level references appear in an index.
How to use it
- Choose the PDF file.
- Set a number prefix and the starting number.
- Set the number of digits and the text size.
- Process and download the numbered PDF.
Accuracy, limits, and good practice
- Keep the prefix consistent across a matter — a prefix like ABC then a zero-padded number is the convention that makes references sortable.
- Use enough digits for the whole production, not just this file: switching from four to five digits mid-set breaks sorting.
- Continue numbering across documents by setting each file's starting number to follow the previous file's last page.
Frequently asked questions
What is Bates numbering for?
Giving every page in a production a unique identifier so it can be cited precisely in filings, correspondence and testimony.
Is it different from page numbers?
Yes. Page numbers restart per document; Bates numbers run continuously across an entire set, which is exactly what makes them citable.
Where should the number sit?
Conventionally the bottom-right corner, positioned clear of existing content so it never obscures the document text.

PDF Bates 編號能做什麼
為 PDF 每一頁蓋上連續的文件管理編號，可自訂前綴、起始號碼、補零位數與文字大小。Bates 編號是法律證據開示與檔案管理的標準做法，因為它讓每一頁都有唯一、可被引用的識別碼。
什麼時候用得上
- 為法律證據開示準備文件組，每一頁都必須能單獨指稱。
- 為送交主管機關或稽核的檔案編號，讓對方能引用特定頁面。
- 管理大型文件卷宗，索引中會出現頁層級的引用。
使用步驟
- 選擇 PDF 檔案。
- 設定編號前綴與起始號碼。
- 設定位數與文字大小。
- 執行處理並下載已編號的 PDF。
精確度、限制與實務建議
- 同一案件請使用一致的前綴——例如 ABC 加補零編號，這種慣例才能讓引用可排序。
- 位數要以整批產出估算，而非只看這一份：中途從四位改五位會破壞排序。
- 跨文件連續編號時，請把每份檔案的起始號碼接續前一份的最後一頁。
常見問題
Bates 編號是做什麼的？
讓整批產出的每一頁都有唯一識別碼，能在書狀、往來文件與證詞中被精確引用。
它跟頁碼不一樣嗎？
不一樣。頁碼每份文件重新起算；Bates 編號跨整批連續，這正是它可被引用的原因。
編號該放在哪裡？
慣例是右下角，並避開既有內容，確保永遠不會蓋到文件本文。
