🔢 Structure of the new unit code

The employer code has 3 joined components: ĐD + ĐT + LH.

• ĐD - unit identifier – Meaning: Companies: enterprise code issued by the business registration office. Budget-related units: budget relationship code; Length: 10 characters (company) / 7 (budget code)
• ĐT - participant type code – Meaning: Participant type managed in the social insurance database; Length: 2 letters
• LH - business type code – Meaning: Per Vietnam's economic sector classification (Decision 27/2018/QD-TTg); Length: 3 characters

💡 Example: old code TD0001D may become 0123456789DNA03 - 0123456789 is the enterprise code, DN the participant type and A03 the business type. Each unit's ĐT and LH codes follow the appendices to Letter 1804.

⚠️ After syncing

1. Reconcile the employee list: Compare headcount and contribution bases with HR records and payroll; contact your local social insurance office about any mismatch.
2. Update employees' personal ID numbers: Citizen ID data must match the national population database, since it replaces the social insurance number.
3. Update the code in your filing software: If you file through an I-VAN service or accounting/HR software, update the new unit code to avoid rejected submissions.
4. Check your digital signature: Electronic social insurance filings require a valid company digital signature.
