How to Print Duplicate Sequential Numbers on Shipping Labels
Product
PDF/Spreadsheet
Device & OS
not provided
Scenario
Generating paired custom shipping labels for cases or items that require matching sequential identifiers and barcodes.
Observed behavior
Requires a batch-generation workflow, script, or mail merge setup that successfully duplicates each sequence number before incrementing it on a master label template.
Before you start

Determine whether your shipping labels are already saved as individual PDFs or if you need to generate them from a master PDF template. If barcodes are involved, ensure your generation method updates the barcode data automatically alongside the sequential number.

Use Spreadsheet Mail Merge to Generate Duplicate Sequential Labels

Create a dataset with duplicate sequential numbers in a spreadsheet, then merge it into a word processor or PDF label template.

The easiest non-programming approach to batch sequence generation is utilizing a mail merge workflow. By generating your paired numbers in a spreadsheet first, you have complete visual control over the numbering sequence and barcodes.

1
Create the spreadsheet dataset

Open a spreadsheet software and create a column named 'Label Number'. Enter your starting number (e.g., 100) in the first two rows, then 101 in the next two. Highlight them and drag the fill handle down to generate the paired sequence.

2
Prepare the label template

Open your shipping label design in a word processor that supports mail merge capabilities. Navigate to the Mailings or References tab.

3
Insert merge fields

Connect your saved spreadsheet as the data source. Insert the 'Label Number' merge field into the appropriate text box and barcode generator field on your template.

4
Merge and export to PDF

Execute the mail merge to generate a new multi-page document containing all your labels. Export or save this final document as a PDF, which is now ready for batch printing.

Use Spreadsheet Mail Merge to Generate Duplicate Sequential Labels
Pro Tip for Spreadsheets: You can use a formula to automatically generate duplicate pairs in your spreadsheet. Type your starting number in cell A1. In cell A2, type '=A1'. In cell A3, type '=A1+1'. Then select A2 and A3 and drag the fill handle down.

Frequently Asked Questions

Can I automatically update barcodes when the sequential number changes on a label?

Yes. Whether you use a PDF script or a mail merge workflow, you can link the barcode generation field to the same data source as your sequential number. When the number increments, the barcode will automatically reflect the new value.

Will my duplicated PDF labels print correctly on a dedicated 4x6 label printer?

Yes. Once you have generated the final batch PDF, ensure your print dialog is set to the correct page size (e.g., 4x6 inches or 100x150 mm) and select 'Fit to Printable Area' in your PDF reader to avoid edge clipping.

Do I need programming knowledge to print sequential PDF labels?

Not necessarily. While using a JavaScript batch script within a PDF editor requires some technical knowledge, utilizing a Mail Merge feature by combining a spreadsheet and a word processor requires zero coding experience.

How can I prevent blank pages from generating during the batch PDF print?

Blank pages usually occur if the label template's margins exceed the printable area of the designated page size. Ensure your master template's dimensions exactly match your final output size and that no invisible paragraph breaks overflow to the next page.
