It prevents the same lead, contact, or account from being entered multiple times, keeping the CRM database clean and ensuring every interaction is tracked against a single record.<\/div>\n<div class=\"gt-section\">\n<h2>How Duplicate Check Works<\/h2>\n<p>Duplicate Check Rules are configured per module. You specify the fields used for matching (such as Email Address and Mobile Number for Contacts). When a record is saved, Zoho CRM checks all existing records for matches. If a duplicate is found, the system alerts the user with a list of potential duplicates and gives them the option to proceed with the save, merge with the existing record, or cancel.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Automatic vs Manual Deduplication<\/h2>\n<p>Duplicate Check prevents duplicates at entry time. For existing duplicates already in the database, use the <a href=\"https:\/\/aaxonix.com\/resources\/glossary\/merge-records\/\" class=\"sp-content-link\">Merge Records<\/a> feature to combine duplicate records and consolidate their related data into a single record.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Industry Example<\/h2>\n<div class=\"gt-example-box\"><strong>Events and Conferences:<\/strong> An events company collects leads from multiple registration forms, trade show scanners, and manual entry. Without deduplication, the same attendee might appear 3 or 4 times in the CRM. Duplicate Check Rules match on Email Address and Mobile Number, alerting reps before saving a new lead if a matching record already exists. This keeps their 50,000+ lead database clean and ensures follow-up communications are not sent multiple times to the same person.<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Related Terms<\/h2>\n<div class=\"gt-related-pills\"><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/merge-records\/\" class=\"sp-content-link gt-related-pill\">Merge Records<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/import-crm\/\" class=\"sp-content-link gt-related-pill\">Import (CRM)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/lead\/\" class=\"sp-content-link gt-related-pill\">Lead<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/contact\/\" class=\"sp-content-link gt-related-pill\">Contact<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/account\/\" class=\"sp-content-link gt-related-pill\">Account<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/audit-log\/\" class=\"sp-content-link gt-related-pill\">Audit Log<\/a>\n<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"gt-faq-item\">\n<h3>What is a Duplicate Check Rule in Zoho CRM?<\/h3>\n<p>A Duplicate Check Rule detects potential duplicate records when a new record is created or an existing one is edited.
