Frequently Asked Questions
The country code for Tanzania is +255. This code is required when dialing Tanzanian phone numbers from outside the country. It uniquely identifies Tanzania in the global telecommunications network, ensuring calls are routed correctly.
Tanzanian phone numbers follow the E.164 international standard, with a maximum length of fifteen digits, and include a country code +255. Domestically, the national prefix is 0, while for international format the national prefix is omitted when dialing internationally. The structure looks like this: +255 [National Significant Number (9 digits)]
The article provides a JavaScript function using regular expressions to validate different Tanzanian number formats, including geographic, mobile, toll-free, premium, shared-cost, and emergency numbers. For production, using a dedicated phone number validation library or API is recommended for more comprehensive validation.
The article includes a Python function using regular expressions to validate various Tanzanian number types, including geographic, mobile, toll-free, premium, shared cost, and emergency numbers. For enhanced validation, consider using a specialized library or API, especially when dealing with user-supplied data.
Tanzania uses various number ranges for different services: geographic (landlines), mobile, toll-free, premium, shared cost, and emergency numbers. Each type has a specific format, detailed in the article's table, which is crucial for accurate validation and routing.
MNP allows subscribers to switch operators while keeping their number, which affects validation and routing. Systems handling Tanzanian numbers should use operator-agnostic validation and real-time operator lookup to ensure accurate call routing, as prefixes may not reflect the current operator.
The TCRA regulates the Tanzanian communications sector. They manage Mobile Number Portability (MNP) and set technical specifications for number handling. Developers should consult TCRA resources for compliance and accurate operator information.
As of June 2023, the major operators are Vodacom, Airtel, and Tigo (merged with Zantel). While prefixes typically indicate the original assigned operator, MNP means the actual operator might differ. Number portability databases or APIs are crucial for accurate routing.
Always consider MNP. Relying only on number prefixes to identify the operator can lead to incorrect routing. Real-time operator lookup through a database or API is crucial for accurate routing in applications handling Tanzanian phone numbers.
Key laws include the Tanzania Communication Regulatory Authority Act of 2003, the Electronic and Postal Communications Act (EPOCA) of 2010 (revised in 2022), and the Universal Communications Service Access Act, 2006. These laws regulate aspects like licensing and operations.
Due to Mobile Number Portability (MNP), prefixes don't reliably indicate the current operator. It's essential to integrate with a number portability database or API or utilize services provided by the Tanzania Communications Regulatory Authority (TCRA) to determine the actual operator for a given number.
Key technical considerations include scalability for the growing market, compliance with TCRA regulations, supporting both legacy and modern telecommunication protocols, and implementing real-time number status verification to manage changes like porting.
While prefixes traditionally indicate the original assigned operator, Mobile Number Portability (MNP) allows users to switch operators while retaining their number. Therefore, relying solely on prefixes isn't reliable for determining the current operator.

Tanzania Phone Numbers: Format, Area Code & Validation Guide
Introduction
Are you developing an application that interacts with Tanzanian phone numbers? This guide provides a deep dive into the structure, validation, and best practices for handling phone numbers in Tanzania, equipping you with the knowledge to seamlessly integrate Tanzanian telecommunications into your systems. We'll cover everything from basic number formats to advanced topics like Mobile Number Portability (MNP) and regulatory considerations.
Quick Reference
For quick access, here's a summary of key identifiers for Tanzanian phone numbers:
Understanding the Tanzanian Numbering System
Tanzania's telephone numbering system adheres to the international E.164 standard (defined in ITU-T Recommendation E.164), ensuring global interoperability. This standard, which you'll encounter frequently when dealing with international numbers, dictates a maximum length of fifteen digits and a structure that includes a country code and a national significant number. This structured approach facilitates clear communication and efficient routing of calls and messages across international borders.
Each Tanzanian phone number consists of:
Number Formats in Detail
Tanzania uses various number ranges for different services. Understanding these distinctions is crucial for accurate number validation and routing. Let's examine each type:
2[2-8]XXXXXXX
6[125-9]XXXXXXX
,7[13-9]XXXXXXX
80[08]XXXXXX
90XXXXXXX
840XXXXXX
,86[01]XXXXXX
11[12]
,999
Implementing Number Validation
Robust number validation is essential for any application handling Tanzanian phone numbers. It ensures data integrity and prevents errors in downstream processes. Here are examples in JavaScript and Python:
JavaScript Validation
This JavaScript function provides a basic validation check. However, for production environments, consider using a dedicated phone number validation library or API for more comprehensive validation, including handling edge cases and potential formatting variations.
Python Validation
Similar to the JavaScript example, this Python function provides a good starting point. For production systems, you should consider using a specialized library or API for more robust validation. This is especially important when dealing with user-supplied data, which can have unpredictable formats.
The Tanzanian Telecom Landscape
Understanding the key players in the Tanzanian telecom market is crucial for contextualizing your development efforts. Here's a brief overview:
As of June 2023, Vodacom, Airtel, and Tigo (now merged with Zantel) dominate the market, collectively holding the lion's share of mobile subscriptions. This information is valuable when considering market reach and potential integration with specific operators. Remember, these number ranges represent the original assigned operator. Due to Mobile Number Portability (MNP), a number might be used by a different operator than the one originally assigned.
Mobile Number Portability (MNP)
MNP allows subscribers to switch operators while keeping their existing phone numbers. This adds complexity to number validation and routing. When dealing with Tanzanian numbers, you should consider the following:
Technical Architecture Considerations
When designing systems for the Tanzanian market, consider these key factors:
Legal and Regulatory Framework
The Tanzanian telecommunications sector operates under a robust legal framework. Key legislation includes the Tanzania Communication Regulatory Authority Act of 2003, the Electronic and Postal Communications Act (EPOCA) of 2010 (revised in 2022), and the Universal Communications Service Access Act, 2006. These laws govern licensing, operations, and consumer protection within the sector. Understanding this framework is crucial for ensuring your applications comply with Tanzanian law. For instance, the Electronic and Postal Communications Act mandates local content/public shareholding requirements for certain license holders. This means that companies operating in the Tanzanian telecom market may need to have a certain percentage of their shares owned by Tanzanian citizens or entities.
Conclusion
This guide has provided you with a comprehensive overview of Tanzanian phone numbers, from basic formats to advanced considerations like MNP and regulatory compliance. By following the best practices outlined here, you can ensure your applications seamlessly integrate with the Tanzanian telecommunications landscape. Remember to stay updated on regulatory changes and industry best practices to maintain optimal performance and compliance.
