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.
The country code for Nauru is +674. This code is essential for international dialing and should always precede the 7-digit local number.
The E.164 format for Nauru phone numbers is +674XXXXXXX, where XXXXXXX represents the 7-digit local number. Storing numbers in this format ensures consistency and facilitates international communication.
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.
Yes, this guide provides a comprehensive overview of Nauru phone numbers, including format, validation, best practices, and information about the underlying telecommunications infrastructure.

Nauru Phone Numbers: Format, Area Code & Validation Guide
This guide provides a comprehensive overview of Nauru's phone number system, equipping you with the knowledge to confidently handle Nauru numbers in your applications. We'll cover the format, validation, best practices, and even delve into the underlying telecommunications infrastructure.
Nauru Telephone Number Format
Let's start with the basics. Nauru uses a streamlined 7-digit numbering system, making it relatively simple to work with.
Quick Reference
Understanding the Structure
Nauru's closed numbering plan reflects its compact telecommunications infrastructure. This standardized approach simplifies number validation and processing for developers like you. Here's a breakdown of the core components:
Service-Specific Prefixes
Prefixes distinguish between service types. Understanding these prefixes is crucial for accurate number routing and validation.
Implementing Nauru Phone Number Handling
Now that you understand the structure, let's explore how to implement this knowledge in your projects.
Validation
Robust validation is crucial. It prevents invalid data from entering your system and ensures smooth operation. Consider these validation patterns:
This code first removes any non-digit characters, then checks the cleaned number against the appropriate regular expression. Notice the inclusion of test cases to demonstrate usage and potential pitfalls. You should always test your validation logic with various valid and invalid inputs.
Formatting
Consistent formatting improves user experience and data consistency. Here's a function to format Nauru numbers:
This function provides both local and international formatting options. Remember, storing numbers in a consistent format, such as the international E.164 format (+674XXXXXXX), is a best practice.
Best Practices for Your Applications
Here are some key considerations for working with Nauru phone numbers:
With these best practices in mind, you can create robust and reliable applications that handle Nauru phone numbers effectively.

method.Nauru's Telecommunications Landscape
Understanding the underlying infrastructure provides valuable context for developers. Nauru's telecommunications landscape is characterized by its streamlined infrastructure, designed for its unique island environment. The network employs a closed numbering plan with the international code +674, creating a simplified dialing experience.
Network Architecture
The telecommunications backbone consists of two primary components:
Mobile Infrastructure: Managed by Digicel Nauru, the digital GSM network provides 3G/4G services in major settlements, with redundant systems for increased reliability. As noted in external sources, Digicel offers a variety of prepaid data packages and roaming options. You should consider these options when developing applications that might utilize mobile data.
Fixed-Line Infrastructure: Operated by the Nauru Utilities Corporation (NUC), the copper-based landline network is supported by a fiber optic backbone for institutional connections and emergency services. The NUC also plays a key role in regulatory compliance and quality of service monitoring.
Coverage and Quality
Nauru boasts impressive coverage across the island:
Service quality metrics are also noteworthy, with average voice service availability at 99.5% and a network reliability target of 98% uptime. However, data speeds can be variable based on location. As a developer, you should consider incorporating fallback mechanisms for areas with variable coverage and implement robust error handling for network transitions.
Future Considerations and the Evolving Landscape
While the current numbering plan is stable, staying informed about potential changes is crucial. The Nauru government, through the Department of ICT, is actively investing in and developing the nation's ICT infrastructure. This includes initiatives to improve service delivery, upgrade infrastructure, and expand coverage. Furthermore, the planned submarine cable connection, funded in part by the Australian Infrastructure Financing Facility for the Pacific (AIFFP), will significantly enhance Nauru's international connectivity. You should monitor NUC announcements for any updates and design your applications with flexibility in mind to accommodate future changes.
Conclusion
This guide has provided you with a deep dive into Nauru's phone number system. By understanding the format, implementing robust validation and formatting, and considering the broader telecommunications context, you can effectively integrate Nauru phone numbers into your applications. Remember to stay informed about future developments and prioritize best practices for a seamless user experience.
