Your NIN provides access to data, so it’s essential to prioritize its security. Here are some practical tips and recommendations for keeping your NIN safe;

1. Safeguard Your NIN Like Other Personal Details

Handle your NIN similar to how you would protect your bank PIN or passwords. It’s information that should not be shared casually.

2. Exercise Caution When Sharing Your NIN

Only disclose your NIN when required and only to verified and reliable sources. Be cautious of requests for your NIN through calls, emails, or messages, as they might be phishing attempts or identity theft schemes.

3. Keep your documents and digital screenshots containing your NIN in a place. 

Ensure that digital copies are safeguarded with passwords or encryption, while physical copies should be stored securely away from any prying eyes of visitors or potential intruders.
