Frequently Asked Questions

Nauru uses a 7-digit phone number system. Landlines typically start with 444, while mobile numbers begin with 555, 666, or 88X. The full international format includes the +674 country code before the 7-digit local number.
Use regular expressions to validate Nauru phone numbers. A general pattern is /^(?:444|555|666|88\d)\d{4}$/. For service-specific validation, use /^444\d{4}$/ for landlines and /^(555|666|88\d)\d{4}$/ for mobile numbers. Always clean the input by removing non-digit characters before validation.
Format Nauru numbers as XXX XXXX locally. For international format, prepend +674 followed by a space and the local format (e.g., +674 444 1234). This ensures consistency and readability.
Nauru's 7-digit system reflects its compact telecommunications infrastructure and closed numbering plan. This standardized approach simplifies number validation and processing.

Using the provided NauruPhoneNumber class offers a structured approach to managing Nauru phone numbers within your applications. This class encapsulates validation, formatting, and number type determination, providing a cleaner and more maintainable solution.
Always validate for length and correct prefixes, handle both international and local formats, store in E.164 format (+674XXXXXXX), clean input before validation, maintain updated prefix mappings, and implement robust error handling.
Nauru's telecommunications infrastructure consists of a mobile network managed by Digicel Nauru and a fixed-line network operated by the Nauru Utilities Corporation (NUC). The network employs a closed numbering plan under the international code +674.
Nauru has high coverage across the island, ranging from 90% in interior regions to 98% in urban areas. Voice service availability averages 99.5%, but data speeds can vary depending on location, so developers should consider fallback mechanisms.
The Nauru government is actively investing in ICT infrastructure improvements. The planned submarine cable connection, funded partly by the AIFFP, will significantly boost international connectivity. Stay informed about these developments and design adaptable applications.
You can implement Nauru phone number validation using the provided Javascript regular expressions. Ensure to remove non-digit characters first. Consider using the example NauruPhoneNumber class for a more structured approach.
Mobile prefixes in Nauru include 555, 666, and the 88X range. The 88X prefix was introduced to accommodate increased demand for mobile services.
