How UD Bates Stamp differs from Adobe Acrobat Bates
Adobe Acrobat Bates numbering burns numbers onto PDF pages. UD Bates Stamp writes numbers into structured document metadata — queryable, not just visible.
Adobe Acrobat Bates numbering
Requires Acrobat Pro licence ($239/year). Burns numbers visually onto PDF pages as rendered text. The number is part of the image — not a queryable metadata field. Changing a number requires re-rendering the page.
Manual numbering in Word or by hand
Error-prone, non-sequential numbering is a common source of discovery sanctions. No verification that the range is continuous or that documents haven't been renumbered after production.
UD Bates Stamp — metadata-embedded numbers
Bates numbers are written into each document's structured metadata, not just printed on the page. The number can be read by any review tool, validated against the bundle index, and verified as unchanged.
UD Bates Stamp — continuous range verification
The .udz bundle index records the full Bates range at creation time. UD Legal Bundle Verify can subsequently confirm the range is intact and no documents have been added, removed, or renumbered.
