Why Every Office Needs a Numbering Machine (And How to Use It)

Why Your Office Needs a Numbering Machine

Mar 20, 2025

Manually numbering documents? That’s slow and error-prone. A Numbering Machine does the work faster—while automatically changing numbers with each stamp.


In this post, I’ll show you what an automatic numbering machine is, why your office needs one, how to use it, how to choose the right type, and what you'll find in the box.


1. Automatic Numbering Machine:

What is It? An Automatic Numbering Machine is a self-inking stamp that automatically prints sequential numbers on documents. With every press, it advances to the next number, saving time and reducing mistakes.

What are the Different Types? Numbering Machines come in 8-digit, 10-digit, and more.

💡Did you Know?: Buying a 10-digit machine doesn't mean you must use all 10 digits. You can set it to print fewer digits, like 4, 6 or 8, depending on your needs. More digits just mean extra flexibility!


2. Why does Your Office Need a Numbering Machine?

You might wonder, “Can’t I just print serial numbers instead?”

While computers can print serial numbers, Automatic Numbering Machines are essential when working with irregular-sized documents (tickets, bank bills, cash sales slips, invoices, purchase orders), handling bulk paperwork without a printer, or needing quick, on-the-spot stamping.

That’s why they’re widely used in off-site offices, banks, hospitals, legal offices, courts, and government agencies—where numbering must be fast, consistent, and hassle-free.


3. How to Use Automatic Numbering Stamps?

1️⃣ Add Ink - Attach the felt pad to the holder and apply a few drops of oil-based ink to the felt pad.

Applying drops of black oil based ink to the holder of the numbering machine.

2️⃣ Set the Starting Number - Using the included stylus, adjust the digits to your desired starting point. For example, if you're stamping invoices and want to begin at 1001, set the wheels to 1001 and adjust the other wheels to the blank position so only the required 4 digits are printed.

Adjust the digits on the numbering machine using the in-box stylus.

3️⃣ Position & Press - Align the machine on your document and press down firmly for a clear, even print.

And that’s it! With each press, the numbers advance automatically—saving you time and effort.


4. What is Included in the Box?

The box includes everything you need to get started with your numbering machine. Here's what's inside:

  • Cleaning the Wheels: To clean the wheels, gently wipe them with a cloth and a small amount of mineral spirits to avoid buildup.
