Data Standards

How We Source & Verify 4D Results

Every 4D result on this site follows strict data standards. Here is how we source, validate and verify every draw record.

Required Before Publication

Every record must include:

• Operator name (Magnum 4D, Sports Toto, Da Ma Cai, etc.)
• Draw date and draw ID
• First, second and third prize numbers
• Special and consolation prize numbers
• Source URL pointing to the operator's official result
• Verification timestamp

Validation Process

Each record goes through automated validation:

• Date format and validity checks
• Number format checks (four-character strings to preserve leading zeros)
• Duplicate record detection
• Source URL accessibility verification

Corrections

If a record contains an error, the corrected entry must be checked against the original source and re-imported with an updated verification timestamp. Historical records are displayed by draw date, not by the date the page was generated.

Coverage

The archive covers Magnum 4D, Sports Toto, Da Ma Cai, Singapore Pools, Sabah 88, Sarawak Cash Sweep, GD Lotto and Perdana 4D. Each filter is a browsing category for easy navigation.
