Maintaining a contact database with high data integrity is essential for any organization. You need your data to be reliable, accurate and complete, otherwise you risk frustrating your customers with the wrong information, being unable to deliver personalized services, and losing faith in your reporting.

One of the biggest threats to data integrity is having duplicate contacts in your database.

In many cases, duplicate contacts are caused by human error. One team member might spell a contact's name wrong, causing it to be added twice. It can also be caused by a contact filling in a form with a different email address or phone number.

In short: duplicate contacts can be a real pain. No business wants to have to deal with them, but the good news is that you don't have to. Here's what you need to know to get rid of duplicate contact data for good.

The best apps to remove duplicate contacts

Some apps offer built-in deduplication features to locate and banish pesky duplicates by merging or deleting them.

For instance, HubSpot has a handy deduplication tool that uses AI to finds duplicate contacts and companies in the CRM. Google Contacts and iCloud also have useful built-in dedupe functions. It's always a good idea to start with your apps' functionality and clean up your data at the source.

However, many apps don't have built-in dedupe functions, or they're limited in quality. For most organizations, it's valuable to choose a dedicated app for data quality and cleansing that works across multiple apps.

To avoid wasting time, money and energy trying to fix duplicate contacts and its repercussions across your organization, here are five of the best apps to help you fix and avoid duplicates in your apps.

How to prevent duplicates when syncing your data

The tools we talked about here are amazing additions to your tech stack when it comes to managing your contact databases and keeping them organized. But another important step in contact management is syncing your contact data two ways.

PieSync is a two-way contact data syncing tool that also has valuable advantages for preventing and merging duplicate contacts.

When you create a sync between your apps, say Google Contacts and HubSpot, you can choose which app has the authoritative data that should be chosen if there's a conflict. This creates a "single source of truth" in your data: one of the benchmarks of a healthy database.

PieSync also defines contacts by their email address, which is how PieSync avoids creating duplicate contacts in different apps. For example, when PieSync sees that one app has a contact named 'Bill' and another has a contact named 'William' - both of which are attached to the same email address - the tool will merge and enrich both contact records.
