How do you handle duplicate contacts with same number?

As an AI, I don't "handle" duplicate contacts with the same number in a real-world CRM or database system. I don't maintain a personal contact list, nor do I perform actions like merging records or sending out communications.

However, based on my extensive training data, which includes information on how CRM systems, databases, and contact management tools typically address this issue, I can describe the strategies and mechanisms used to handle duplicate contacts with the same phone number.

This is a very common challenge in any organization that manages customer or prospect data, as duplicates can lead to:

Poor Customer Experience: A customer might receive duplicate finland phone number list communications, or different agents might contact them for the same issue, leading to frustration.
Wasted Resources: Marketing campaigns might target the same person multiple times, or sales teams might duplicate efforts.
Inaccurate Reporting: Duplicate records inflate lead counts, distort conversion rates, and skew analytics.
Data Integrity Issues: Inconsistent information across multiple records for the same individual makes it difficult to trust the data.
Common Strategies for Handling Duplicate Contacts with the Same Phone Number:

Duplicate Detection Rules:
Proactive Prevention: This is the first line of defense. When a new contact is being entered (manually, via a web form, or through an import), the system is configured to check if a record with the same phone number (or email address) already exists.
Matching Criteria: Duplicate rules define what constitutes a "match." For phone numbers, this usually involves normalizing the number to a standard format (like E.164) and then performing an exact match. Some advanced systems might use "fuzzy matching" to account for minor variations (e.g., +12125551234 vs. 1-212-555-1234).
