I just came across this link that allows you to download and print your National ID using the NIMC app
Simply supply your NIN and registered phone number.
The mobile phone application identified as MWS: NIMC Mobile ID was credited as property of the Nigerian government.
Registered subscribers could retrieve private information about their Drivers License Number (DLN), Voters Identity Number (VIN), Bank Verification Number (BVN), National Passport Book Number (PPN), and Tax Identity Number (TIN).
“In fact, you only require your full National Identification Number (NIN), your Mobile Number and a PIN to access and protect the app,”
SIMPLE STEPS TO Download it
1) download the NIMC ( national identity management commission) mobile application on playstore or follow this simple link ( https://play.google.com/store/apps/details?id=com.nimcmobile&hl=en )
2) then supply your NIN and your registered phone number. ( Do not input your BVN )
3) your digital ID number will be displayed
4) you can print it out immediately.
