NRIC and FIN format explained

        

          Every NRIC and FIN has nine characters: a prefix letter, seven digits and a check
          letter, for example S1234567D. The prefix tells you which
          series the number belongs to.

NRIC checksum algorithm

        
    
          
  1. Multiply the seven digits by the weights 2, 7, 6, 5, 4, 3, 2 and add the results.
    2. 
          
  2. Add 4 if the prefix is T or G.
    3. 
          
  3. Divide by 11 and keep the remainder (0 to 10).
    4. 
          
  4. 
            Look the remainder up in the check-letter table:
            J Z I H G F E D C B A for S and T, or
            X W U T R Q P N M L K for F and G.
          
    5. 
        

        

          Worked example. For S1234567:
          1×2 + 2×7 + 3×6 + 4×5 + 5×4 + 6×3 + 7×2 = 106.
          106 divided by 11 leaves a remainder of 7, and position 7 in the S table is
          D, so the full number is S1234567D.
        

      


      

        

          
What this tool is good for

          

            Use it for registration forms, regex checks, validation messages, API fixtures,
            spreadsheet samples, demos, and automated tests that need realistic Singapore
            NRIC or FIN-shaped values.
          

        

        

          
What it does not do

          

            A checksum-valid value is not a real-world identity check. This tool cannot
            verify issuance, personhood, citizenship, residency, pass status, or ownership.
          

        

        

          
Safer by design

          

            Numbers are generated and checked by plain JavaScript in your browser. The values
            you generate or paste are never sent to Aivoryx, AI services, or a validation
            server. We only collect anonymous page-visit statistics.
          

        

      


      

        
Frequently asked questions

        

          What is a Singapore NRIC generator?
          
A Singapore NRIC generator creates random numbers that follow the NRIC or FIN format and pass the checksum, so developers and QA testers can fill in forms, seed databases and write automated tests without using a real person’s identity number.

        

        

          Are the generated NRIC numbers real?
          
No. Every number is random, synthetic test data. A value that passes the checksum only has the right structure; it does not prove that the number was ever issued or that it belongs to anyone.

        

        

          What is the format of an NRIC or FIN?
          
Nine characters: one prefix letter (S or T for NRIC; F, G or M for FIN), seven digits, and one check letter calculated from the prefix and digits. Example: S1234567D.

        

        

          How is the NRIC checksum calculated?
          
Multiply the seven digits by the weights 2, 7, 6, 5, 4, 3, 2 and add the results. Add 4 if the prefix is T or G. Take the remainder after dividing by 11 and look it up in the check-letter table: J Z I H G F E D C B A for S and T, or X W U T R Q P N M L K for F and G. For S1234567 the sum is 106, the remainder is 7, and the check letter is D.

        

        

          What is the difference between NRIC and FIN?
          
An NRIC (National Registration Identity Card number) is issued to Singapore citizens and permanent residents and starts with S or T. A FIN (Foreign Identification Number) is issued to foreigners holding long-term passes and starts with F, G or M. Both share the same nine-character layout.

        

        

          Why is the M-series FIN handled differently?
          
M-series FINs were introduced on 1 January 2022. The format is public, but the official checksum rule has not been published, so this tool generates and checks M-series values by format only instead of claiming checksum verification.

        

        

          Is generated or validated data uploaded?
          
No. Generation, validation, copying and exports all run locally in your browser. The numbers you generate or paste are never sent to a server.

        

        

          Is this NRIC generator free?
          
Yes. It is free, has no sign-up, and has no limit on how many numbers you generate.

        

        

          Can I use these values in production?
          
No. Use them only as synthetic test data. Do not use generated NRIC or FIN values for authentication, account recovery, KYC, or any workflow involving a real person.
