Supplemental Productions: Should You Continue the Bates Range or Start Over?

The first production went out as SMITH000001 through SMITH002847. Three weeks later, another group of documents needs to be produced. Where should the new Bates numbering begin?

There is no single formatting rule that fits every matter. Production protocols, agreements, court orders, client requirements, or established practice may dictate the answer. But from a practical production standpoint, there are a few questions that make the decision much easier to manage.

Continuing the existing range is often the simplest approach

If the supplemental documents are part of the same production stream and nothing requires a different convention, continuing the existing sequence is often operationally clean.

Using the example above, the next production would begin at SMITH002848. The new documents remain part of one unique sequence, and anyone looking at a Bates number can immediately tell that it belongs somewhere after the original production.

The practical advantage of continuing a Bates range is continuity: one prefix, one sequence, and no duplicate page identifiers.

A new prefix can make sense when the production needs to stand apart

There are also situations where a distinct prefix or numbering convention may be more useful. A supplemental production may be going to a different requesting party, may involve a separate category of records, or may need to be clearly distinguishable from an earlier set.

For example, a team might use SMITH000001 for an original production and SMITHSUPP000001 for a later supplemental set. That can make the distinction obvious, but it also means the matter now has more than one Bates sequence to track.

Neither approach is automatically better. The important thing is that the convention is intentional, documented, and consistent with whatever governs the production.

Avoid reusing a Bates range

Whatever convention you choose, duplicate Bates identifiers are worth avoiding. If SMITH001250 already identifies a page in the original production, using SMITH001250 again for a completely different page in a supplemental production creates unnecessary ambiguity.

That ambiguity tends to show up later, when someone cites a Bates number in an email, deposition, motion, or review note and two different pages appear to match it.

Unique page identifiers are the whole point of Bates numbering. Supplemental productions should preserve that usefulness.

Keep a record of where every production ended

The easiest supplemental-production problem to prevent is forgetting where the last sequence stopped.

After a production is delivered, preserve at least the final Bates range and enough identifying information to know what that range belonged to. A simple production log can save a surprising amount of reconstruction later.

• Production date
• Bates prefix
• Beginning Bates number
• Ending Bates number
• Recipient or requesting party when relevant
• A short description of the production

The point is not to create administrative work. It is to make the next production easy to continue without searching old emails or opening previously produced files just to find the last number.

Be careful when the original production changes

Supplemental productions become more complicated when the new work is not simply “more documents.” Sometimes a document from the original production is being corrected, replaced, or produced again in a redacted form.

That is not merely a question of what number comes next. The team may need to decide whether the replacement should retain a prior identifier, receive a new identifier, or be handled according to a specific production protocol.

Those decisions should be made deliberately before numbering begins rather than being improvised after the supplemental set has already been processed.

Different recipients may justify different conventions

A matter can involve productions to multiple parties, agencies, experts, or other recipients. In those situations, a single universal sequence may be clean, or separate sequences may be easier to administer.

The practical question is whether a Bates number should identify a page uniquely across the entire matter or only within a particular production stream. Once that convention is chosen, consistency matters more than cleverness.

The simple takeaway

For a straightforward supplemental production in the same matter, continuing the existing Bates range is often the simplest operational choice. A new prefix or sequence can make sense when the supplemental set needs to be clearly separated or when the governing production requirements call for it.

Whichever route you take, preserve the prior ending number, avoid duplicate identifiers, and decide the convention before processing the new documents. Supplemental productions are much easier when nobody has to guess where the numbering should begin.
