Why Bates numbers land in the wrong order across files

When you number a folder of PDFs in one pass, the numbering follows the order the files were added, which is usually alphabetical by filename - and neither the filename order nor the file-modified order is the order a production is served in. The sequence is still continuous, so nothing looks wrong until a receiving party reads the set. The check that catches it compares the Bates range of each file against the order the files are meant to appear.

How the wrong order happens

Numbering tools take a list of files and number them front to back. The list usually comes from a file picker or a folder drop, so it is sorted by name. VOL0002 then VOL0010 sorts before VOL0003 in a plain string sort, and a production that was served volume by volume ends up numbered in an order no one intended.

The result is a set where every number is unique and the sequence has no gaps. That is exactly why it survives a visual check: the defect is not in the numbers, it is in the mapping between numbers and documents.

What the order check looks at

The audit reads the Bates stamp from each page, groups the stamps by file, and asks whether the range boundaries are monotonic across the set in the order you declared. A file whose start number is lower than the previous file's end number is reported as out of order, with both filenames and both pages named.

  • A gap inside a file is reported against that file and page.
  • A duplicate number is reported against both occurrences.
  • A change of prefix or padding mid-set is reported as a warning, because it usually means two numbering runs were merged.

The fix is renumbering, and that is a different job

We do not stamp or renumber at launch - stamping and index generation are the fix, and they ship with Prepare. What this check gives you is the exact list of files and pages that would need it, and the range each file currently occupies, so the renumbering run is a decision rather than a guess.

Frequently asked questions

Can I reorder files and number them again in one pass?

Yes, in whichever tool you use for numbering. The check does not care how the numbers were applied; it cares whether the finished set runs in the order it will be served.

Does the audit change my files?

No. Every input is hashed before and after the run, and a run that changed an input fails. The audit is read-only by construction.

guide Continuing Bates numbers on a supplemental production The second production in a matter starts at the number after the last page of the first, with the same prefix and the same zero padding. Get that wrong in either direction and the set either overlaps numbers already used or leaves a gap that a receiving party will ask about in writing. Continuity is checkable arithmetic, and it is the one thing a rolling production cannot verify by eye. guide Adobe stamps in the wrong order - here is why Acrobat's Bates numbering runs over the file list exactly as it was given to it. Select a folder and the list is name-sorted; the numbers are then continuous, unique and in an order nobody chose. The set looks perfect and is numbered by filename. This page explains the mechanism, the two ways it goes wrong, and the check that finds it in a minute. hub Watermark glossary A short glossary of the words used around PDF watermarking, each defined in one or two sentences before any detail: what a watermark is, the difference between text and image marks, what diagonal, background, tiled and confidential mean, and why a dynamic watermark is not the same as a fixed one. Every term links back to the page that shows it in use. guide How to watermark a PDF To watermark a PDF, upload the file, choose a watermark style, type your wording, set the opacity to somewhere between 25% and 35%, apply it to every page and download the marked copy. The whole procedure takes about a minute in a browser, needs no software, and the original file is not changed - you keep the marked copy as a new file. guide What is a PDF watermark? A PDF watermark is text or an image placed on the pages of a document to say something about it - who it belongs to, what state it is in, or who may read it. It becomes part of the page rather than a note attached to the file, so it appears in prints, screenshots and single-page extracts, and it carries no technical protection: anyone can still open, copy and forward the document. guide Batch watermarking PDF files Batch watermarking means applying the same mark to several PDFs so they look like one set. With a browser tool you do it by settling the settings once - style, wording, opacity, colour - then running the tool once per file with those same settings, which takes under a minute each and produces consistent output without installing anything or creating an account.
