# Error "Phone has already been taken"
This message appears when your form is trying to create (or update) a Shopify customer, but the phone number submitted is already used by another customer in your Shopify admin.
✅ Nothing is broken! Shopify is preventing duplicate phone numbers for customer records (depending on your store settings).
***
### 🔍 Why this happens
When a customer submits the form, Powerful Form sends the information to Shopify (example: Email, Name, Phone).
If the **phone number** is already attached to an existing Shopify customer, Shopify may reject the request and return:
**“Phone has already been taken”**
Common causes:
* You are testing multiple submissions using the same phone number
* Different customers share one phone number (family / company phone)
* The form is set to create customers, but your store requires phone numbers to be unique
***
### ✅ How to solve it
**Steps**
1\. Open the app > click **Forms** > open the form you want to edit
2\. Click the **Integration** icon on the left side > enable **Shopify** and click on **Shopify** option
3. Find **If customer already exists** and choose:
➡️ **Continue and ignore the error**
4. Click save.
#### **✅ Why use this option?**
This option helps prevent the submission from failing when the customer already exists in Shopify (usually because the email is already in your Customers list).
With this setting:
* If the email already exists, the form submission can still continue
* Shopify will not create a duplicate customer and make no change to Shopify customer account
* The app will skip the “already exists” error and move on
> ⚠️ Note: This option does **not** update customer information.\
> If you want to update fields like **phone, name, or address**, choose **Continue and update customer information** instead.
4\. Click ” **Save”** to update the form
