# Display Customer's Tax Number using Customer Note

This guideline gives information about how to display your Customer's Tax Number using Customer Note of Shopify.

If Customer's Tax number (*in this article we will simply use VAT number*) is required, you will need to show them on the invoices.
By default, Shopify does not allow adding additional fields on checkout, but you could try this alternative solution:
  
When customers sign-up for an account on your store, you can ask them to write down the *VAT number*, by simply adding a field to this page. The information is automatically stored in **Customer Note**, which will then be displayed on our *V*ify PDF Invoice app. 
Here are the steps to do so:

**Step 1**:
* In your Shopify admin, go to the ***Online Store*** → ***Themes*** page.
* Click the ***...*** button next to ***Customize*** on your current theme, then click ***Edit code***.

**Step 2**:

* Select **main-register.liquid** file in the left sidebar. (in the Sections file)
* Insert the following code snippet inside the *<form>*. We do recommend inserting the code just before the Email field.
_<label for="company_no">VAT Number</label>_
_<input id="company_no" type="text" name="customer[note][VAT Number]" placeholder="VAT Number" />_

If you need other information, simply replace *VAT Number* with it. The, rememeber to hit **Save** to apply the change. 
Here is how it should look on the Shopify Admin:
