Guangzhou social security has two numbers. What about the provincial and municipal levels?

Can be merged. According to the relevant regulations for inquiring about social security in Guangzhou, people with provincial and municipal social security numbers can merge their social security numbers, but only if they are not registered in Guangzhou, they can transfer part of the provincial social security to the municipal social security and apply for retirement in Guangzhou. If it is a household registration in Guangzhou, it can be transferred without the above restrictions.
