Solutions to Issues in Sending NIN to 55019 & 66019 for JAMB Profile Code Registration

As the 2025 Unified Tertiary Matriculation Examination (UTME) approaches, one of the first steps for candidates in Nigeria is to generate their JAMB profile code by sending their National Identification Number (NIN) to the shortcodes 55019 or 66019. This profile code is essential for completing the registration process. However, many candidates have faced challenges when attempting to send their NINs and generate their profile codes. These issues have sparked confusion and frustration among candidates who are eager to complete their registration and ensure their participation in the 2025 UTME.

This comprehensive guide explains the common problems candidates encounter during this process and provides step-by-step solutions to resolve them. Whether you are dealing with SMS failures, incorrect formats, or network-related issues, we’ve got you covered.

Common Issues and How to Resolve Them

1. SMS Sending Failure: Why It Happens and How to Fix It

One of the most frequently reported issues is the failure of the SMS to go through when candidates attempt to send their NIN to the shortcodes 55019 or 66019. The reasons behind these failures can vary, but here are the most common causes and their solutions:

1. Insufficient Airtime: The most straightforward cause of an SMS failure is insufficient airtime. Without at least N50 worth of airtime, the message cannot be processed. Always check your balance before sending the message to ensure it meets the required amount.
2. New SIM Cards: Many candidates who have recently switched to new SIM cards experience difficulties because the SIM has not yet been registered or validated in the system. If your SIM card is new, make sure it is properly registered with your mobile network provider. You can confirm registration by visiting your network provider’s office or checking online.
3. Network-Specific Problems: Some mobile networks, notably Airtel and 9mobile, have been reported to have consistent issues when sending the NIN to the JAMB shortcodes. If you’re using either of these networks, we recommend switching to MTN or Glo to avoid the problem. These networks are more likely to successfully process the message.
4. SIM Restrictions: Some SIM cards may be blocked from sending profile code requests if they have previously been used for generating codes for other individuals. If you suspect this is the issue, consider using a different SIM card.
5. Phone Settings and SMS Configuration: Ensure your phone is capable of sending SMS messages, and check that no settings are blocking your outgoing messages. Additionally, verify that the phone number you are using is linked to your NIN.
6. Special Packages and Services: If you are using special packages, such as postpaid plans, promo bundles, or have enabled the Do Not Disturb (DND) feature, these could block outgoing SMS messages. Disable these services temporarily and try again.

Solution: Ensure you have sufficient airtime, your SIM is properly registered, and you are using a supported network like MTN or Glo. Also, ensure that the SMS settings on your phone allow for outgoing messages.

2. The “Invalid Character Found” Error: How to Correct the Formatting

Some candidates encounter the error message “Invalid character found” after sending their NIN to the JAMB shortcode. This typically happens when the SMS format is incorrect. It’s crucial to follow the exact format required by JAMB.

1. Correct Format: Your SMS should follow the format: [NIN 00123456789], where “NIN” is followed by your 11-digit National Identification Number (without any dashes or special characters).
2. Spacing: Ensure there is only one space between the word “NIN” and the NIN number itself. Do not use double spaces or other separators. A common mistake is including extra spaces or characters which lead to the error.

Solution: Carefully type your NIN in the correct format with the proper spacing and no special characters.

3. The USSD Option: A Reliable Alternative

For candidates who are still facing difficulties with SMS-based registration, JAMB has provided an alternative method for generating a profile code using USSD codes. This method can bypass some of the issues experienced with SMS.

1. To Use the USSD Option: Dial 550191NIN# or 660191NIN# on your phone.
2. Follow the prompts to input your NIN and generate your profile code. This method has proven to be effective for many candidates experiencing SMS-related problems.

Solution: If SMS continues to fail, try the USSD method for profile code generation.

4. Temporary Network or System Issues: Patience is Key

Some candidates may encounter persistent problems due to temporary issues such as poor network connections or technical glitches with JAMB or the National Identity Management Commission (NIMC) systems. These issues are typically resolved over time as the systems are updated or the network connection improves.

If you’ve tried all the solutions above and the issue is still not resolved, the best course of action is to wait. Keep checking back after some time, as these types of issues usually correct themselves.

Solution: If you are facing persistent issues that cannot be resolved immediately, it may be a temporary system or network issue. Be patient and try again later.

5. Lost SIM Card: What to Do if You Cannot Retrieve Your Profile Code

For candidates who have lost the SIM card previously used to generate their profile code, JAMB has set up a solution. Since JAMB strictly prohibits the use of a different SIM to generate a profile code for the same NIN, candidates in this situation must visit a Computer-Based Test (CBT) centre.

1. JAMB’s Provision: JAMB has set up a feature at CBT centres to help candidates who have lost their original SIM card. At the CBT centre, you can verify your identity and have a new profile code generated using your current SIM.

Solution: If you’ve lost the SIM you used for registration, head to the nearest CBT centre to resolve the issue and generate a new profile code.

Conclusion: Complete Your JAMB Registration with Ease

The process of creating your JAMB profile code by sending your NIN to the shortcodes 55019 or 66019 is essential for the 2025 UTME registration. However, technical glitches, network failures, and incorrect formatting can make the process frustrating for candidates. By following the solutions outlined in this guide, you can troubleshoot and resolve common issues to ensure a smooth registration process.

Remember, if you encounter any difficulties, check your airtime, confirm your SIM card registration, use the correct format, and consider using the USSD option. If you’re still experiencing problems, give it some time as network issues or system glitches can be temporary.

Ensure your registration is completed on time, and take advantage of the resources available to help you succeed.
