# Working With Customer Specific Product Numbers as a Customer
### How to configure product numbers
You can access all existing customer-specific product numbers by opening the list view that you can access by clicking "Company" > "My product numbers" in the customer portal menu.
This page allows you both to view all existing connections, edit existing connections, as well as add new connections.
A look at the product numbers list view
#### Add new product numbers
**From the list view**
Click the button "Create new product number".
Inside the new modal, add the shop product number first, and in the second field, add your product number. Click "Create" to confirm & add the connection.
Your product number has been connected! 🎉
**From the PDP**
Depending on your settings for the addon, you will be able to either find a link to the list view or a text input field, allowing you to directly connect a custom product number with the product you're currently viewing.
#### Edit existing product numbers
**From the list view**
Click on the green icon on the row that lists your product. A modal will appear, just like the one you get if you create a new link.
Adjust your values and click "Update" to apply changes.
**From the PDP**
Next to your custom product number you will find an icon. If you click this, you will be directed to the list view where you can edit your entry as described one section earlier.
#### Delete existing product numbers
**From the list view**
Click on the red icon on the row that lists your product.
You will be asked to confirm your choice. If you want to delete multiple entries, you can check "Do not ask again", which will prevent this modal from appearing for 24 hours.
**From the PDP**
It is currently not possible to delete product numbers while from the PDP view.

### FAQ
* My shop already uses the product number "12345", but I want to add my custom product number "12345" as well for a product. Is this possible?
* Yes, this is possible. Both values are connected, but do not overwrite each other.
* If I search for "12345", will I be able to find both products associated with the number?
* No, the custom product number takes precedence in search over the shop's article number.
* Is it possible to accidentally use the same custom product number twice?
* No, you will receive an error message, preventing you from doing that.
