Genesys Cloud enables users with External Contacts > Contact > Edit permissions to modify contact information through the Contacts > External Contacts menu. Users can search for contacts or filter by division, then select a contact row and click Edit Contact to update information. The system supports full E.164 formatted phone numbers, which are searchable; non-E.164 numbers can be added but are not searchable, and extension-only numbers are not supported. Genesys Cloud applies a default country code of +1 for the United States, configurable by administrators. Key limitations include: contacts imported from Salesforce cannot be edited, and contact divisions cannot be modified—division changes require deleting and recreating the contact record. Users can only edit contacts they created; after updating information, changes are saved via Save or Save and Close options, with optional note management available.
