How to Set Up Magento 2 International Telephone Input Module?

Prerequisites

• Magento 2.3.x or 2.4.x installation

• PHP 7.2, 7.3, 7.4, or 8.x

• Composer package manager and CLI access

Step 1: Download Module Files

Developers can avail the module through official distribution channels. The package includes both Community and Enterprise edition files. Archive extraction reveals the src directory structure.

The download contains src/app/code/Magery/IntlTelInput for core files. Enterprise features exist in src/app/code/Magery/IntlTelInputEe directory.

Step 2: Copy Files to Magento

• Navigate to the Magento 2 root directory first.

• Copy the src contents to the root folder.

• Verify file permissions match Magento standards afterward.

The directory structure must match module requirements. Incorrect placement causes module detection failures.

Step 3: Enable Core Module

Execute the following command sequence:

php bin/magento module:enable Magery_IntlTelInput  
php bin/magento setup:upgrade  

The system registers the module in Magento's configuration. Database schema updates apply telephone field modifications.

Step 4: Enable Enterprise Features (Optional)

Enterprise edition users execute other commands, like:

php bin/magento module:enable Magery_IntlTelInputEe  
php bin/magento setup:upgrade  

Enterprise features activate B2B-specific telephone field enhancements.

Step 5: Clear Cache

Cache clearing provides proper and complete module initialization. Run php bin/magento cache:clean, then cache:flush. Module functionality requires fresh cache generation.

Configuration Settings for Magento 2 International Telephone Input Module

1. Accessing the Configuration Panel

Log in to the Magento Admin Panel interface. Navigate to Stores → Configuration → Customers section. Select International Telephone Input from the menu.

2. General Configuration

• The Enabled setting controls module activation per store. The default value remains Yes for immediate functionality. Store View scope allows multi-store configuration.

• The Allow Dropdown option provides clickable country flags. Dropdown displays reveal scrollable lists with search functionality. Keyboard navigation provides accessibility for all users.

• Custom CSS Container accepts space-separated class names. Classes apply to the telephone field wrapper element. Common examples include custom-phone-input or branded-telephone styling.

• Separate Dial Code displays country codes outside the fields. The format appears as +1 | 2025550123. Input fields contain national numbers without country codes.

• The Utils Script loads JavaScript formatting utility functions. Number formatting occurs during customer typing. Placeholder examples, such as (201) 555-0123, guide proper entry.

• Validation Settings integrate Google's libphonenumber library. Real-time checks tally numbers against country-specific rules. Error messages display for invalid formats.

3. Country Settings Advanced Configuration

The Allowed Countries configuration provides multi-select country options. Administrators choose specific countries for the customer dropdown display. The default selection includes all countries.

Limiting countries provides a better user selection experience. Common practice restricts options to shipping destination countries. Configuration changes need a cache refresh for activation.

Initial Country Mode Options:

• None Mode displays the first allowed country. No automatic detection processes occur with this setting. Single-country stores enjoy reduced JavaScript overhead.

• Auto Mode uses the ipinfo.io service for geolocation detection. The system falls back when service becomes unavailable. HTTPS connections provide accurate country detection results.

• Configured Mode lets administrators set specific default countries. All users experience consistent initial country selection. Regional stores gain from reduced API call volume.

Preferred Countries Configuration:

• Administrators specify frequently-used countries for list prominence. Preferred countries appear above the divider line of the dropdown. The configuration format accepts codes like us,gb,ca,au entries.

• Max recommendations suggest limiting to 5-10 countries. Display order follows the entered code sequence.

4. Advanced Configuration Options

The Custom Input IDs feature targets the initialization of non-standard fields. Developers target specific telephone inputs using unique identifiers. Several IDs stay separated with commas like phone1,phone2,emergency-contact.

Configuration applies to these specific Magento pages:

• Customer Registration at customer/account/create

• Customer Account Edit at customer/account/edit

• Address management pages for new and existing entries

JavaScript Initialization Details:

• The module uses RequireJS for dependency management systems. Initialization triggers through data-mage-init attribute configurations. Custom parameters pass via JSON format structures.

• Example initialization: data-mage-init='{"intlTelInput": {"preferredCountries": ["us", "gb"]}}'

Validation Rule Customization:

The validate-phone-intl rule checks compliance with the international format. Custom validation messages support multi-language translations. AJAX web forms receive validation without page reloads.

5. Plugin Behavior Configuration

Dropdown Behavior Settings: Container positioning adapts to available viewport space. Dropdown width matches the input field dimensions. Outside clicks or the Escape key closes selection menus.

Number Formatting Behavior: As-you-type formatting transforms input during entry. Paste operations apply proper formatting to copied numbers. Backspace navigation respects established format boundaries.

Error Handling Configuration: Invalid country codes trigger visible error state indicators. Network failures activate fallback interface displays for continuity. Validation messages appear below affected telephone fields.

RELATED QUESTION "Should developers limit country list or keep all available?"

Limit countries to actual shipping destinations for experience. Customers prefer shorter, relevant lists over comprehensive options. Shorter lists improve selection speed and user satisfaction.
