Code to Check TIN Number Online Using Your Phone in Nigeria (2025 Guide)

Code to Check TIN Number ; In Nigeria, every individual and business registered with the Federal Inland Revenue Service (FIRS) or the Joint Tax Board (JTB) must have a valid Tax Identification Number (TIN). This number is essential for tax compliance, business registration, and official transactions.
But what if you’ve forgotten your TIN or want to confirm if you already have one? The good news is you can easily check your TIN number online using your phone without visiting a tax office.
Understanding the TIN in Nigeria
A Tax Identification Number (TIN) is a unique number issued to individuals and businesses for proper tax documentation. It is used to track tax obligations, confirm compliance, and identify taxpayers across Nigeria. As of 2025, all TIN registrations are managed by either:
- Joint Tax Board (JTB): Responsible for TIN registration for individuals not registered with the Corporate Affairs Commission (CAC).
- Federal Inland Revenue Service (FIRS): Issues TIN to registered businesses and companies in Nigeria.
If you want to check your TIN, you can do so conveniently from your mobile phone through different methods.
Why You May Need to Check Your TIN
Checking your TIN number online using your phone in Nigeria may be necessary if:
- You’ve forgotten your TIN number.
- You recently registered your business and want to confirm if a TIN has been generated.
- You want to verify if your TIN is valid before using it for banking, contracts, or government applications.
- You are applying for loans, government grants, or business opportunities that require proof of tax registration.
Code to Check TIN Number Online Using Your Phone
In 2025, the easiest way to check your TIN number in Nigeria is through the official TIN verification portal provided by the Joint Tax Board (JTB). The platform works on both mobile phones and computers, but since most Nigerians use mobile devices, here’s how to use your phone:
Step 1: Visit the JTB TIN Verification Portal
Open your phone’s browser (Chrome, Safari, Opera, or Firefox) and go to https://tinverification.jtb.gov.ng. This is the official website for checking TIN numbers online.
Step 2: Choose Your Search Criteria
The portal allows you to search for your TIN using:
- BVN (Bank Verification Number)
- NIN (National Identification Number)
- Registered Phone Number
- Corporate Affairs Commission (CAC) Registration Number for businesses
Step 3: Enter Your Details
Enter the relevant detail (e.g., BVN, NIN, or phone number) in the provided field and click the search button.
Step 4: View Your TIN
If you have a TIN, the system will display your Tax Identification Number along with your full name or registered business name.
Using USSD Code to Check TIN Number
As of 2025, the Joint Tax Board (JTB) and Federal Inland Revenue Service (FIRS) are gradually rolling out a USSD code service that allows Nigerians to check their TIN using a simple shortcode. The USSD service works without internet, making it convenient for people in areas with poor network coverage.
Here’s how it works (pilot stage in selected states):
- Dial *805# on your mobile phone.
- Follow the on-screen prompts to choose “TIN Verification”.
- Enter your NIN, BVN, or registered phone number.
- Your TIN will be displayed as an SMS message.
Note: This USSD service is still being tested and may not yet be active nationwide. Always confirm through the JTB verification portal.
Checking TIN Number via SMS
In addition to online and USSD methods, some states in Nigeria (like Lagos) allow TIN verification via SMS. For instance:
- Send TIN <Your BVN> to a designated number provided by your state’s tax authority.
- You will receive your TIN as a text message.
This option may vary depending on your location. It’s best to confirm with your State Inland Revenue Service.
Alternative Ways to Check TIN on Phone
- Through Your Bank: Some Nigerian banks now display your TIN when linking your BVN or NIN to an account. Check your bank’s mobile app or internet banking portal.
- Through FIRS Offices: You can also request your TIN details by visiting the nearest Federal Inland Revenue Service office.
- Through CAC Registration: If you registered your business via CAC, your TIN may already be attached to your company documents.
How Long Does It Take to Retrieve Your TIN?
Most online TIN verification checks are instant if your records are already in the JTB or FIRS system. However, if you recently registered, it may take a few days for your details to reflect. Always keep your NIN, BVN, or CAC registration number handy for quicker searches.
Common Issues When Checking TIN Number Online
Some users may experience issues while checking their TIN number online using their phone. Common challenges include:
- No record found: This usually means your TIN has not been generated or your details were entered incorrectly.
- Portal downtime: The JTB verification portal may sometimes be unavailable due to maintenance.
- Mismatch in details: Ensure your BVN, NIN, or phone number matches the one used during TIN registration.
Why TIN Verification is Important

- Ensures you are tax compliant in Nigeria.

- Necessary for government contracts, tenders, and loans.
- Helps confirm your business legitimacy to partners and investors.
