A Bates number has to do two jobs: identify where a page came from and give it a unique place in the sequence. A good format does both in as few characters as possible and stays the same for the whole matter.
Here's how each part works, with examples you can copy.
Short and fixed. 3 to 6 letters is typical: a party name (SMITH), client code (ACME) or role (PLTF, DEF).
One prefix per producing party. Then nobody confuses whose page 000147 is.
Add a volume label only if agreed.ACME-VOL02-000147 helps with large rolling productions but makes every citation longer.
No spaces or special characters. They cause trouble in file names and review platforms.
03
How many digits?
Zero padding keeps all numbers the same length so they sort correctly: ACME000009 comes before ACME000010.

999,999
Most matters
7

Large productions
8
99,999,999
Very large or multi-year matters
Pick enough digits for the whole matter at the start. Changing the length later breaks sorting.
04
Suffixes and confidentiality labels
Suffixes or a separate label mark pages covered by a protective order, for example -CONF or a line reading CONFIDENTIAL or ATTORNEYS' EYES ONLY. Use the exact wording in the order.
Magic Soft PDF Bates Numbering supports a suffix and a separate confidential note, and you can drag the note to its own spot on the page in the preview.
05
Where to put the stamp
Bottom right is the most common spot, and where people tend to look first.
Keep a clear margin so the stamp doesn't sit on text, signatures or existing page numbers.
If documents already have footers, use an option that moves the stamp clear of existing text.
Use a plain font and a size readable when printed, usually 9 to 11 pt.
The software offers six positions (three across the top, three across the bottom) and checks against existing header and footer text when you turn that option on.

Example formats
Format
When it suits
ABC000001
Simple single-party production
SMITH-000001
Party name, easy to read aloud in a deposition
ACME-VOL01-000001
Rolling productions split into volumes
DEF_00000001
Very large set with 8-digit padding
ACME-000001-CONF
Pages under a protective order
07
Format mistakes to avoid
Changing the prefix or padding partway through.
Restarting at 1 for each file.
Reusing numbers after a page is withdrawn. Leave the gap and log it instead.
Long prefixes that make citations awkward.
Summary
Use a short prefix per producing party, pad to enough digits for the whole matter, add a suffix only when pages need a label, and stamp bottom right clear of content. Then apply it to the whole set in one batch.
Frequently Asked Questions
Frequently Asked Questions
There isn't one universal standard. A short prefix plus a 6 to 8 digit zero-padded number is the most common format.
Six digits covers up to 999,999 pages and suits most matters. Use 7 or 8 for very large productions.
Bottom right is most common. The key is a clear margin so it doesn't cover content.
Yes. Add it as a suffix or a separate note using the wording in the protective order.
Usually not. A short party or client code keeps citations readable.
