From files to a clear plan

Three simple steps.

  1. 01

    Choose your number format

    Set a starting number, prefix, optional suffix and minimum digit count. Six digits turns 1 into 000001; longer numbers are never truncated.

  2. 02

    Add each document’s page count

    List documents in the order you will stamp them. Use the arrows to move a document. Each range begins immediately after the preceding range ends.

  3. 03

    Review and download the ranges

    Check each first and last number, the total pages and the next available number. Download the CSV and use the same order and settings when stamping.

The practical details

A few useful answers.

How is a Bates range calculated?

The last number equals the starting number plus the page count minus one. A 12-page document starting at DOC-000001 ends at DOC-000012. The next document begins at DOC-000013.

Does this calculator stamp my documents?

No. This free tool plans the ranges and exports a CSV. To put Bates numbers on PDFs and images, open BatesFast and sign in for one free preview run.

What happens when a number has more digits than my setting?

Digit padding is a minimum width. A six-digit setting formats 1 as 000001, while 1000000 remains 1000000. The calculator never cuts digits off a number.

Can I get page counts from my PDFs?

Yes. The free PDF page counter reads multiple PDFs locally and can pass the successful page counts into this same range calculator on the counter page. No document upload or sign-up is required.

Are my document names or ranges saved?

Your entries remain in the current page and are not sent as tool analytics. Refreshing or leaving the page clears them. Use Download ranges as CSV to keep your own local copy.
