When working in Vietnam for multiple companies, many foreign workers worry that their social insurance contributions will be "divided" and difficult to process when they want to withdraw them. In reality, this is one of the most common misconceptions, especially among those preparing to leave Vietnam or who have already quit their jobs. So, how does the Vietnamese social insurance system actually operate? And when withdrawing social insurance contributions in a lump sum, are the periods of employment at multiple companies combined?

Conditions for Foreigners to Withdraw Social Insurance Benefits in a Lump Sum

According to Decree 143/2018/ND-CP, foreign workers can receive a lump-sum social insurance benefit upon termination of their employment contract or expiration of their work permit without renewal.

However, for the application to be processed quickly, the social insurance agency needs to confirm that you are no longer participating in social insurance at any unit and that the entire process has been fully updated in the system. If the data is incomplete or not synchronized, the processing may be delayed.

According to the 2014 Social Insurance Law, each employee is only issued one unique social insurance number throughout their working life in Vietnam. This number acts as a legal identifier, helping the social insurance agency track your entire participation history, regardless of how many companies you work for. This means that, in essence, social insurance is not managed on a company-by-company basis, but on an individual employee basis. Each time you change jobs, the new contributions will continue to be recorded in the same system, not creating a completely independent record.

When withdrawing a lump-sum social insurance payment, are the periods of contributions combined?

The answer is yes, but with one important condition: the data must be complete and validly verified. When you submit your application for a lump-sum social insurance payment, the social insurance agency will not process each company separately, but will calculate the benefit amount based on your entire period of participation. This means that all periods of social insurance contributions at multiple companies will be combined into a single total.

This is a very important point, as it helps prevent employees from being disadvantaged even if they have changed jobs multiple times.

Why are there cases where contributions cannot be combined in practice?

Although the principle is to combine contributions, in reality, many applications still encounter difficulties during processing. The reason is often not due to legal regulations, but rather to the data status.

If one of the companies has not completed the finalization of your social insurance records when you leave, the system may not have fully recorded your contribution period. Furthermore, discrepancies in personal information between different periods, or the existence of multiple different social insurance numbers due to inconsistent registration, can also prevent data from automatically linking. In these cases, the social insurance agency will need time to check, adjust, or merge the data before processing your benefits.

Is it necessary to merge social insurance books before withdrawing benefits?

In many cases, merging social insurance books is almost mandatory before submitting your claim.

If you have multiple books or scattered data, the social insurance agency will require you to merge them into a single code. This step ensures that your entire contribution history is accurately recorded and free from duplication or omissions. Merging books is not overly complicated legally, but if not done beforehand, your social insurance withdrawal application may be delayed or require additional information.

If you have returned to your home country, merging data and withdrawing social insurance can still be done through authorization. However, in cases involving multiple companies and inconsistent data, remote processing will often take longer. The authorization document must be properly prepared and, if signed abroad, must be notarized and legalized by the consulate. This is a crucial factor for the application to be accepted and processed correctly.

A common mistake is only checking your social insurance records after you've left your job or are about to leave Vietnam. At that point, if problems arise, such as missing data, incomplete records, or duplicate numbers, you won't have much time to resolve them. Proactively checking early helps you detect and address issues from the start, especially if you've worked for multiple companies. This is crucial to ensuring that all information is ready and there are no interruptions when you submit your application.
