General information
TIN and BRN (Business Registration Number) validation will be added to the Validate Taxpayer's TIN API starting on August 1, 2026, according to HASiL's SDK 1.0 release notes. This will improve buyer data accuracy for e-invoice submissions.
Field validations have also been tightened by recent SDK updates: Scientific notation is no longer accepted in amount fields; all values must use conventional numeric format; State Code 17 is now limited to consolidated e-invoices issued in Malaysia or transactions outside of Malaysia.
Operational action: Clean up buyer master-data right away. Prior to the August production change, gather precise BRNs, match buyer records with HASiL data, and validate validation logic.
