Are CDCFIB Application Number and Examination Number the Same?
Short answer: No.
Your CDCFIB Application Number and Examination Number are usually issued at different stages of the recruitment process.
The Application Number is generated when you successfully submit your CDCFIB recruitment application, while the Examination Number is issued later to candidates who are shortlisted for the CBT examination.
If you are being asked to provide your Application Number for screening, you should not automatically use your Examination Number unless CDCFIB specifically instructs candidates to do so.
The safest approach is to retrieve your original Application Number from your registration confirmation email.

Where Can I Find My CDCFIB Application Number?
Your CDCFIB Application Number can be found in the confirmation email sent to you immediately after completing your recruitment application. Remember that confirmation email sent to the email address you used during registration?
To find it:
1. Open the email address you used during registration.
2. Search for CDCFIB or the recruitment confirmation message.
3. Open the email confirming successful application.
4. Look for your Application ID or Application Number.
For example, candidates who applied for the Nigeria Immigration Service (NIS) may see an application number similar to:
NIS/2025/XXXXXXXX
This is the number CDCFIB is currently asking shortlisted candidates to provide.
Applicants for other agencies such as:
- Nigeria Security and Civil Defence Corps (NSCDC)
- Nigeria Correctional Service (NCoS)
- Federal Fire Service (FFS)
will have application numbers that correspond to their selected service.
If you still have access to the email you used during registration, this is usually the fastest way to recover your application number.

Where Can I Find My Examination Number?
Your examination number was issued much later when CDCFIB shortlisted candidates for the Computer-Based Test (CBT).
To find it:
- Check the CBT invitation email sent to you.
- Open your examination slip.
- Review any CBT notification messages you received.
The examination number is the number you used during the CBT stage and is different from the original application number issued during registration.
5 Proven Ways to Find the Right CDCFIB Number
If you’re unsure whether you’re looking at your CDCFIB Application Number or Examination Number, here are five proven ways to identify the correct number.
1. Check Your Registration Confirmation Email
The easiest way to find your CDCFIB Application Number is to open the confirmation email you received immediately after submitting your application.
This email usually contains your Application ID, registration details, and the service you applied for.
For example, applicants who applied for the Nigeria Immigration Service (NIS) may find an application number that begins with:
NIS/2025/
If you’re looking for your Application Number, this should be your first stop.
2. Check Your CBT Shortlisting Email
If you were shortlisted for the Computer-Based Test (CBT), CDCFIB would have sent you another email containing your examination details.
This email usually contains your Examination Number, examination venue, date, and instructions for the CBT exercise.
If the number appears in a CBT invitation email, it is most likely your Examination Number rather than your Application Number.
3. Review Your Examination Slip
Candidates who participated in the CBT can also check their examination slip.
Your slip may contain:
- Examination Number
- Reference Number
- Candidate details
- Examination centre information
Carefully compare the details on the slip with those in your registration confirmation email to determine which number is which.
4. Search Your Email Using CDCFIB Keywords
If you have hundreds of emails in your inbox, use the search function and try keywords such as:
- CDCFIB
- Application Successful
- CBT Invitation
- Recruitment
- Immigration Service
- NSCDC
- Fire Service
- Correctional Service
Many applicants have successfully recovered both their Application Number and Examination Number using this method.
5. Compare Both Emails Side by Side
The most reliable way to identify the correct number is to compare your registration confirmation email with your CBT shortlisting email.
In most cases:
- The registration email contains your Application Number.
- The CBT email contains your Examination Number.
Comparing both messages side by side can quickly help you determine which number CDCFIB is requesting for the next stage of the recruitment process.
I Can’t Remember Either Number. What Should I Do?
If you can’t remember your CDCFIB Application Number, don’t panic. You’re not alone.
Many applicants completed their registration more than a year ago, and since then some have changed phones, lost access to email accounts, deleted screenshots, or misplaced their registration slips.
The good news is that your Application Number can usually be recovered if you still have access to the email address you used during registration.
Start by checking:
- Your email inbox
- Spam or Junk folder
- Promotions folder (for Gmail users)
- Archived emails
- Screenshots saved on your phone or cloud storage
- Downloaded registration documents
When searching your inbox, try keywords such as:
- CDCFIB
- Application Successful
- Recruitment Application
- Nigeria Immigration Service
- NSCDC
- Federal Fire Service
- Nigeria Correctional Service
Your original registration confirmation email should contain your Application Number.
If you are still unable to locate it, we’ve created a detailed step-by-step guide that explains all available recovery options:

The guide covers how to search for your registration details, recover lost application records, and what to do if you no longer have access to the email address used during registration.
What About the Reference Number on My Slip?
Another question many applicants are asking is whether the Reference Number shown on their CBT slip is the same as their CDCFIB Application Number.
The confusion is understandable because some candidates can only find a Reference Number on their examination documents and are wondering if they can use it for screening instead of their Application Number.
At the moment, CDCFIB has not issued any official statement confirming that the Reference Number and Application Number are the same.
For that reason, we recommend locating your original Application Number rather than assuming the Reference Number will be accepted.
The easiest way to verify this is to check the confirmation email you received when you first submitted your CDCFIB application. That email should contain your Application Number and other registration details.
If you can no longer access your registration email or cannot find your Application Number, read our guide on How to Retrieve Your CDCFIB Application Number for step-by-step instructions on recovering your details.
Until CDCFIB provides further clarification, candidates should avoid replacing their Application Number with a Reference Number during screening or verification processes.
Can I Use My NIN Instead?
A lot of applicants have suggested that CDCFIB should allow candidates to verify their records using their NIN.
However, there is currently no official announcement stating that NIN can replace the application number during screening or verification.
For now, your best option is to recover your application number from your registration email.

Final Thoughts
If you’re struggling to remember your CDCFIB application number, the first place to check is the confirmation email you received immediately after registration.
If you’re looking for your examination number, check the email and documents sent when you were shortlisted for the CBT examination.
The two numbers are issued at different stages of the recruitment process, so you should not assume they are the same.
Before the physical screening begins, take a few minutes to search your email inbox and save copies of both numbers for future reference.
