In Ghana, the journey to link every mobile SIM card to a verified identity has been a transformative step toward a secure and inclusive digital economy. At the heart of this initiative is the Ghana Card, a biometric national identity card that ties together various identification systems, including the Tax Identification Number (TIN), passport number, and digital residential address. This blog post explores the history, mechanics, and recent developments of Ghana’s SIM card registration process, revealing how it’s shaping the nation’s future.

A Brief History: Building a National Identity System

Ghana’s quest for a robust identification system began in earnest in the early 2000s. In 2002, a Technical Committee laid the groundwork for the National Identification System (NIS), aiming to cover all citizens and legally resident foreigners. The goal was ambitious: to enhance public services, combat crime, and streamline transactions like passport acquisition and banking. By 2003, the National Identification Secretariat was established, and in 2006, the National Identification Authority (NIA) was formalized under the NIA Act (Act 707).

Initial attempts at issuing national ID cards faced challenges. In 1973, cards were issued in border regions, but logistical issues halted the project. A 2008 mass registration exercise also struggled, with many Ghanaians not receiving their cards due to technical limitations. These setbacks underscored the need for a modern, biometric-based system, leading to the introduction of the Ghana Card in 2011.

The Ghana Card: The Backbone of SIM Registration

The Ghana Card, issued by the NIA, is a biometric ID in ID1 format, equipped with features like a Dual Interface Chip, UV printing, and an E-passport symbol. It serves as proof of identity, citizenship, and residence for Ghanaians and legally resident foreigners. Its mandatory use for transactions—ranging from banking to voter registration—made it the ideal tool for SIM card registration.

In 2021, the Ministry of Communications and Digitalisation, led by Minister Ursula Owusu-Ekuful, launched a nationwide SIM card registration exercise, effective October 1, 2021. The directive required all SIM holders to link their cards to their Ghana Card, aiming to curb fraud, track criminal activities, and build accurate telecom demographics. Unlike previous attempts, this exercise leveraged the Ghana Card’s biometric verification, ensuring robust authentication.

How SIM Registration Works

• Individuals: Ghanaians and foreign residents staying over 90 days must use their Ghana Card PIN. Foreign visitors (staying less than 90 days) can use passports or ECOWAS cards, but SIMs deactivate after 30 days unless a Non-Citizen Ghana Card is obtained.
• Process: Users dial *USSD code 404# to submit their Ghana Card PIN and date of birth. Mobile Network Operators (MNOs) verify details with the NIA, followed by biometric capture (fingerprints, photo) at a service provider’s office.
• Limits: Individuals can register up to 10 SIMs across networks; foreigners are capped at 3. Businesses link SIMs to a director’s Ghana Card.

Connecting the Dots: TIN, Passport, and Digital Address

The Ghana Card’s Personal Identification Number (PIN) is the linchpin that integrates multiple systems, creating a unified identity framework.

• Tax Identification Number (TIN): Since April 1, 2021, the Ghana Card PIN has replaced the TIN for individual tax purposes, following a collaboration between the Ghana Revenue Authority (GRA), NIA, and Registrar-General’s Department. A transition period allowed both identifiers until December 31, 2021. Taxpayers can link their TIN to their Ghana Card PIN via the GRA’s self-service portal, streamlining tax-related transactions.
• Passport Number: The Ghana Card is mandatory for passport applications, with its PIN captured on passports to verify citizenship. This ensures only eligible Ghanaians receive passports, reducing identity fraud. For SIM registration, passports serve as an alternative for foreigners or Ghanaians abroad lacking a Ghana Card.
• Digital Residential Address: The GhanaPostGPS system assigns a unique digital address (e.g., GA-543-0125) to every 5m x 5m grid in Ghana. This address is required during SIM registration and Ghana Card applications, enhancing location accuracy for services like banking and emergency response. Users can obtain their digital address via the GhanaPostGPS app or website.

This integration ensures that a single, verified identity can be used across government and private sector services, from tax filing to mobile connectivity.

Recent Developments: Progress and Innovations

The SIM registration exercise, initially set to conclude on March 31, 2022, faced extensions due to logistical challenges and the need for broader Ghana Card adoption. The deadline was first extended to July 31, 2022, and later to May 31, 2023. By June 2023, Minister Owusu-Ekuful announced that 28 million SIM cards had been successfully registered, a significant milestone.

Key developments include:

• Shortcode for Verification: On May 1, 2023, the National Communications Authority (NCA) introduced **USSD code 4021#**, allowing users to check SIMs linked to their Ghana Card. After entering their PIN and date of birth, users receive an SMS listing registered numbers, enabling them to delink unauthorized SIMs.
• Newborn Registration: In July 2023, a pilot program led by Vice President Dr. Mahamudu Bawumia began issuing Ghana Card numbers to newborns, integrating them into the NIS from birth.
• Penalties for Non-Compliance: Unregistered SIMs faced barring from voice and data services, with enforcement starting September 5, 2022, as announced by MTN Ghana.
• Business and Foreigner Provisions: Businesses undergo due diligence, linking SIMs to a director’s Ghana Card, while non-resident foreigners use passports or ECOWAS cards, with strict validation via global databases.

Challenges and Criticisms

Despite progress, challenges persist. Some Ghanaians, especially in rural areas, faced difficulties obtaining Ghana Cards due to limited registration centers. The cost of Non-Citizen Ghana Cards (USD 120) has drawn criticism, particularly from ECOWAS nationals who argue it contradicts regional treaties. Technical issues, like verification failures, also prompted users to visit NIA offices for resolution.

Looking Ahead: A Digital Future

Ghana’s SIM card registration, anchored by the Ghana Card, represents a bold step toward a secure, digitized society. By linking SIMs to biometric identities and integrating TIN, passport numbers, and digital addresses, the government is building a robust ecosystem that enhances governance, reduces fraud, and fosters economic inclusion. As of 2025, the focus remains on ensuring universal Ghana Card coverage and refining verification processes to address lingering challenges.

If you haven’t linked your SIM to your Ghana Card, dial *USSD code 404# or visit your service provider today. For those without a Ghana Card, NIA offices and mobile registration services are expanding access. Join the millions shaping Ghana’s digital future—one verified identity at a time.
