Setting a field as unique prevents duplicate entries for identifiers like PAN numbers, GST numbers, customer codes, or contract IDs.<\/div>\n<div class=\"gt-section\">\n<h2>What is a Unique Field in Zoho CRM?<\/h2>\n<p>When a field is marked as Unique in Zoho CRM, the system rejects any new or edited record that would create a duplicate value in that field across the module. This is configured in the field&#8217;s properties in Setup (not in the Page Layout, unlike Mandatory or Read-Only settings).<\/p>\n<p>Unique Fields are typically text or number fields used as business identifiers: customer account numbers, purchase order references, GST registration numbers, or employee IDs in a Custom Module for HR data.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Unique vs Duplicate Check Rule<\/h2>\n<p>A <a href=\"https:\/\/aaxonix.com\/resources\/glossary\/duplicate-check-rule-zoho-crm\/\" class=\"sp-content-link\">Duplicate Check Rule<\/a> in Zoho CRM checks across a combination of fields (e.g., same First Name + Email = duplicate). A Unique Field enforces uniqueness on a single field only. Both can be used together for comprehensive deduplication.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Industry Example<\/h2>\n<div class=\"gt-example-box\"><strong>Wholesale Distribution:<\/strong> A B2B distributor marks the &#8220;Customer Code&#8221; Custom Field on Accounts as Unique. When a sales rep tries to create a second Account with the same customer code, CRM rejects the save and shows a validation error, preventing duplicate account records that would distort the billing and reporting.<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Related Terms<\/h2>\n<div class=\"gt-related-pills\">\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/custom-field-zoho-crm\/\" class=\"gt-related-pill sp-content-link\">Custom Field<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/duplicate-check-rule-zoho-crm\/\" class=\"gt-related-pill sp-content-link\">Duplicate Check Rule<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/mandatory-field-zoho-crm\/\" class=\"gt-related-pill sp-content-link\">Mandatory Field<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/merge-records-zoho-crm\/\" class=\"gt-related-pill sp-content-link\">Merge Records<\/a>\n<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"gt-faq-item\"><strong>What is a Unique Field in Zoho CRM?<\/strong><\/p>\n<p>A Unique Field in Zoho CRM is a field that enforces no two records in the same module can have the same value.
