Rubber Stamps are a way to print non-address information on a label for reference. They are commonly used to double check you're putting a label onto the right package.

A gif showing the Create a Shipping Label form. When the checkbox next to 'Rubber Stamps,' is checked, some boxes appear below where you can enter information that will appear at the bottom of the physical label below the barcode.

You can create Rubber Stamps several ways:

  • In the Create a Single Label form, check the "Rubber Stamps" checkbox.

  • When uploading a spreadsheet to create a labels, you can map columns of your spreadsheet data to the three Rubber Stamp fields.

  • When Importing Orders from an eCommerce Integration, you can go to Settings / Integrations / Edit your Integration / Edit Field Mapping to assign data from your eCommerce platform to Rubber Stamps.  

Where are Rubber Stamps printed?

Rubber Stamps are printed in the bottom box of a label. You can have up to three Rubber Stamps, but they have strict character-length restrictions of 34 characters per line.

Pro Tip: UPS only allows for two Rubber Stamps instead of three like USPS if you plan on shipping with UPS, that's something to be aware of!

Rubber Stamps don't have much room!

If the data goes over 34 characters, instead of cutting it off Pirate Ship will force a line break onto the next Rubber Stamp line... but once all 3 lines are filled, then the rest of the data will be cut off. Because of this, if the data you're using is very long, it's recommend to ONLY assign it to Rubber Stamp 1, and leave the other 2 rubber stamps unused, so that it can flow into those lines.

Common uses for Rubber Stamps:

  • Order ID, so you can match the label to a packing list generated by another system (but have you thought about using Pirate Ship's packing lists instead?)

  • Order Items, which works if your order item names are very short, and if you don't get orders with lots of different items.

  • Batch Name, which is a custom name you give a batch when you're creating it in Pirate Ship. This gives you the freedom to come up with unique ways to group & reference orders.

NOTE: If you're shipping with USPS®, Rubber Stamps cannot be applied to international labels. However, Rubber Stamps do appear on UPS® international labels 😉
