# Prevent Client Side Duplicate Records
### Here are two ways DeDupeD can prevent client-side duplicate records:
1. **Prevent duplicates on field changes:** To see how DedupeD helps you prevent duplicates on field changes, follow the steps given below:
* Navigate to **Sales Hub** --> Contact Entity --> Click on **‘New’** button.
* A new contact record form will appear.
* Enter a name in the **‘First Name’** field.
* If a contact record with the same first name already exists, then you will see a pop-up that will prevent you from creating a duplicate.
* If, for some business reasons, you want to ignore duplicates and continue creating the record, then click on **‘Ignore’**.
2. **Prevent duplicate upon saving the record:** To prevent duplicates upon saving the records, follow the steps given below:
* Enter a detail in CRM and click on **‘Save’.**
* If a record with same details already exists in the CRM, then you will see a pop-up that will prevent you from creating a duplicate.
* If, for some business reasons, you want to ignore duplicate and save the record, then click on **‘Ignore and Save’**.
