People registering a birth can, at the same time, apply for an IR number to be allocated to the child using the information provided to DIA during the birth registration application process.
In near real time, DIA send by secure online file transfer information extracted from the birth registration form including the child’s full name, sex, citizenship status and birth registration number. Additionally, the full name, address and date of birth of both mother and father are provided.
The transferred information is held by IR in a secure network folder. IR compares the child’s surname, first name and date of birth provided by DIA against its own records. Where there is no match IR staff will create an IRD number record for the child.
The IRD number registration process requires recording the reference number of the identity document used to verify the identity of each new person record. In the case of children, the birth registration record is the only identity record available for them.
At the point of creating a new IRD record, if the identity reference number is a duplicate of one used previously, the record will not be created.
