So the old Sri Lankan NIC has a 3-digit serial number. And currently, on average there are 900 childbirths that happens a day (correct me if I’m wrong). And these numbers are vastly depleted compared to several decades before.
So statistically, there had to be a 4-digit number of childbirths per day a couple of decades back. How did they manage to issue NIC numbers just with 3-digit serial numbers?
Old format: YYDDDSSSCA
Y – Last 2 digits of the birth year
D – No of days until the birthday if it was in a leap year.
S – Serial number
C – Check Digit
A – Character to denote if the individual is eligible to vote (V) or not (X)
Note: The new format that’s been issued since 2016-01-01, doesn’t have this issue as it has a 4-digit serial number. Also, note that the new format has the full year in 4-digits to remove the clash between 1900+ and 2000+ birth years, and dropped the vote eligibility character. (New format: YYYYDDDSSSSC)
Or is there something going on, the statistics won’t say?
