USSD Retrieval (*346#) NIMC Portal NIMC Mobile ID App Enrollment Centres Network Providers Tips FAQs

The National Identification Number (NIN) is an 11-digit number issued by the National Identity Management Commission (NIMC). It is required for SIM registration, BVN linking, passport applications and many other official services. Below are the most common and official ways to check your NIN in 2025.

1. Check NIN via USSD (*346#)

How to use:

1. Dial *346# from the mobile number you used during NIN enrollment.
2. Choose the option labeled "NIN Retrieval" (or similar prompt).
3. Follow on-screen prompts — your NIN will be displayed if your number is linked.

Note: The USSD service typically charges a small fee (commonly around ₦20), which is deducted from your airtime. Charges and shortcodes can change — if the code doesn't work, try the other methods below or contact NIMC.

2. Check NIN via the NIMC Self-Service Portal

NIMC’s official website provides self-service options for checking and printing your NIN slip.

1. Go to the official NIMC website: https://nimc.gov.ng.
2. Find the Self Service Portal or NIN Retrieval section.
3. Log in with your registered phone number or email and follow the verification prompts.
4. Once verified, you can view, download or print your NIN slip.

Tip: If you don’t have a portal account, use the registered mobile number or enrolment details to create one, or proceed to an enrollment centre for assistance.

3. Use the NIMC Mobile ID App

NIMC provides a mobile app (often called Mobile ID or similar) that displays a virtual copy of your NIN and basic identity details.

1. Download the official NIMC Mobile ID app from Google Play or the Apple App Store.
2. Open the app and sign in with your NIN and the phone number linked to your enrollment.
3. After verification, your virtual NIN and identity summary will be visible on the dashboard.

Apps and names change occasionally — always verify you’re downloading the official NIMC app (check developer name and official links on nimc.gov.ng).

4. Visit a NIMC Enrollment Centre

If online or USSD options fail, visiting an official NIMC centre is a reliable fallback.

1. Locate the nearest NIMC office or accredited enrollment centre (NIMC website lists centres).
2. Bring your valid ID (passport, driver’s license, or birth certificate) and any enrollment slip or receipt.
3. Request assistance for NIN retrieval — an officer can search using your personal details and provide your NIN.

This option is recommended if you suspect errors in your enrollment or need physical documentation (NIN slip).

5. Contact Your Network Provider (Telecom)

Some mobile network operators provide NIN services or shortcodes for retrieval and verification.

1. Contact your telecom’s customer service via their official helpline, app, or website.
2. Ask if they support NIN retrieval using your registered SIM number — they may guide you through USSD or account checks.
3. Visit a network provider’s service centre if needed, with ID and proof of ownership of the SIM.

For security, telcos will verify that you own the number before sharing any NIN details.

Important Tips & Safety Advice

• Always use official channels: NIMC website, official NIMC apps, sanctioned USSD codes and accredited centres.
• Keep your NIN private: Treat your NIN like sensitive financial information — don’t share it unnecessarily.
• Verify domains and apps: Confirm URLs and developer names before entering personal data.
• Save records: Store your NIN slip (digital or printed) in a secure place for future use.
• Expect occasional changes: Codes, fees or apps may be updated — if something doesn’t work, check the official NIMC site or contact NIMC support.

Frequently Asked Questions (FAQs)

What if the USSD code *346# doesn't work?

USSD codes and services sometimes change. If *346# fails, try the NIMC portal or Mobile ID app, or visit an enrollment centre. Check nimc.gov.ng for updates.

Can I retrieve my NIN using someone else's phone?

USSD retrieval typically works only from the phone number linked to your NIN enrollment. For other phones, use the NIMC portal or visit a NIMC centre with ID.

How long after enrollment can I access my NIN?

Processing times vary; in many cases your NIN is available within a few days of enrollment, but some cases may take longer. If too much time has passed, contact NIMC or visit an enrollment centre.

This guide provides general instructions for checking your NIN. Procedures, USSD shortcodes, fees and apps can change — always confirm details on the official NIMC website (nimc.gov.ng) or by contacting NIMC support.
