Primary One Internet System (P1-IS) Online Registration

Parents who intend to use the P1-IS in Phase 2C / 2C Supplementary are required to set up their SingPass 2-Step Verification (2FA). Parents are advised to set up their SingPass 2FA early if they have not done so.

For more information on the 2FA setup, please visit the SingPass website.

Parents who wish to familiarise themselves with the details of online registration can refer to the P1-IS Guide.


The Primary One Internet System (P1-IS) serves as a channel to facilitate the registration of children during Phase 2C and Phase 2C Supplementary. Parents who register online will need to produce the original of each required document to the school that the child is successfully registered into, when requested by the school or upon reporting to the school. 

Online Registration via P1-IS

Parents may register online if,

  • your child is eligible for registration in Phase 2C or 2C Supplementary
  • your child’s birth is registered in Singapore and the child holds a Singapore-issued Birth Certificate
  • both parents have valid SingPass with 2FA setup
  • both parents are Singapore Citizens or Singapore Permanent Residents at the time of your child’s birth

In addition, single parents may register online via the P1-IS if (i) only that parent’s particulars are reflected in the child’s Birth Certificate, or (ii) one parent is deceased.

The P1-IS is accessible 24 hours during the following periods:

  • Phase 2C
