为 PDF 添加贝茨编号
为每一页加盖连续的控制编号。
使用方法
上传您的 PDF，设置前缀和起始编号，然后下载结果。每一页都会依次获得补零的连续编号。
什么是贝茨编号？
它是加盖在文件集每一页上的一串连续编号（例如 ABC0000001）——法律和档案团队用它在大批量文件中为每一页建立唯一标识，是行业标准做法。
我可以自行设置起始编号和前缀吗？
可以——您可以选择任意前缀（例如案件编号或批次代码）以及起始编号；数字会自动补零至 6 位。
Where does the Bates number appear on the page?
In the corner of each page, positioned to stay clear of the page's normal content, consistent with standard legal production formatting.
Can I run this again on an already-numbered PDF to continue the sequence?
Yes — set the starting number to continue where the last batch left off, useful when numbering a document set across multiple upload sessions.
Is Bates numbering the same as page numbers?
Similar idea, but Bates numbers usually include a fixed prefix (like a case ID) and stay constant across an entire document production, not just one file — use Add Page Numbers instead for plain sequential numbers without a prefix.
Why do legal teams use Bates numbers instead of regular page numbers?
Because a normal page number resets with every file, and Bates numbers don't. In litigation, e-discovery, and depositions, every page across an entire document production needs one identifier that's never repeated, so anyone on the case can cite an exact page — like ABC0000042 — instead of describing which file and which page inside it. That's also why it's sometimes called “Bates stamping.”
Can I add a suffix after the number, not just a prefix?
Not currently — this tool adds your prefix before the number (like CASE-0000001), with no separate suffix field after it. If your production needs text after the number too, you'll need to add that separately for now.
