Bates numbering for email correspondence: why and how
Sequential numbering turns a stack of emails into a document you can cite page by page and compare across copies. Where it helps, how to switch it on when ordering a PDF archive, and what a number alone does not prove.
What Bates numbering is
Bates numbering is sequential page identification: every page gets a unique marker such as ARCH-000001, ARCH-000002 and so on. It came from legal practice, where pointing at one page out of a thousand is easier than describing it — the Ivanova email of 12 March, second page.
- Internal archives use it too, wherever several copies of one set have to be reconciled.
Why number an email set
Numbering solves three practical problems.
- References: a protocol, letter or act can cite a page number, and the other side finds it without a chain of clarifications.
- Copy reconciliation: if the set was transferred twice, matching numbers show the copies are identical.
- Completeness: an unbroken sequence without gaps is visible at a glance.
Where to switch it on in eml-pdf.com
Numbering is applied to the single chronological PDF you can order on top of the individual message PDFs.
- In the same request you pick the order — oldest first or newest first — and can add a contents page; undated messages go last.
- It is also worth enabling SHA-256 checksums, so the archive ships a file with hashes of the packaged PDFs and attachments.
- When the set leaves the company, stamp the PDF pages — CONFIDENTIAL, PRIVILEGED, DRAFT or your own text — and pick a template: standard, clean, or branded with a company name in the footer.
How to check the result
Before processing, review the preflight inventory: discovered messages, attachments, duplicates, warnings and how many messages count toward the free allowance.
- After conversion, open the contents page and the manifest.csv or manifest.xlsx index — the status of every message should match what you expected.
- The errors.csv report lists messages that did not process: their absence from the PDF is a visible failure to investigate, not a silent loss.
- Finally, download the archive before the one-hour access window ends and keep it next to your source export.
What a number does not prove
A page number helps you cite and compare; by itself it proves nothing about authenticity, completeness of collection, authorship or legal admissibility.
- Checksums work the same way: SHA-256 lets you compare file bytes before and after transfer, but it says nothing about who created the original message or when.
- PDFs and hashes are tools for reading and reconciling; conclusions about evidence belong to your procedure and your jurisdiction.
A short checklist
Record the source and the export date.
- Keep the original message files — they remain the primary record.
- Order the merged PDF with numbering and a contents page.
- Reconcile the index and the error report against the expected set.
- Enable checksums and verify them after download.
- Fetch the package within the hour and keep your own copy independent of the service.
