How Sri Lanka ID Card Verification Works
Every Sri Lankan National Identity Card (NIC) issued by the Department for Registration of Persons (DRP) follows a mathematical standard. Because identity information is directly encoded into the number sequence, authentic ID numbers can be verified instantaneously in your browser without contacting government databases.
Format & Length Audit.
The verification engine checks for 10 characters (9 digits + V or X)
for pre-2016 issues, or exactly 12 numeric digits for modern cards.
Demographic Day Code Extraction.
The 3-digit day-of-year code (001–366 for males, 501–866 for females)
is extracted and mapped against Sri Lankan calendar algorithms to verify valid birth date and leap year status.
Format Mapping & Checksum.
Old format IDs are cross-mapped to 12-digit numbers by inserting the century prefix (19)
and departmental zero-padding, allowing seamless cross-system verification.

Official Privacy Law & DRP Database Clarification
Can you check a Sri Lanka ID card number by full name online? No. Under Sri Lanka's Personal Data Protection Act No. 9 of 2022 and confidentiality regulations administered by the Department for Registration of Persons (DRP), citizen names, residential addresses, and photos are not publicly searchable.
NIC Info executes mathematical and structural validation entirely inside your web browser. No identity card numbers or personal demographic queries are ever transmitted to any external server.

No. The Sri Lanka Department for Registration of Persons (DRP) does not publish an open online directory linking names or addresses to NIC numbers due to citizen privacy safeguards under the Personal Data Protection Act. NIC Info performs algorithmic format verification without storing or transmitting personal data.
In the old 9-digit format, 'V' designates an eligible voter registered on electoral lists at the time of issue. 'X' designates a non-voter or person exempt from voting. In the modern 12-digit format, letters are omitted in favor of a final numeric check digit.
For male citizens, the 3-digit day code is the calendar day of the year from 001 (January 1) to 366 (December 31).
For female citizens, 500 is added to this value, resulting in a day code between 501 and 866.
