In case of repeated purchase: when the insured person's domicile is the same as that of the last insured person, he/she shall go through the formalities of receiving benefits at his/her domicile and enjoy the basic old-age insurance benefits; Where the domicile is inconsistent with the last insured place, those who have been insured at the last insured place for 10 years will receive treatment at the last insured place; Those who have been insured for less than 10 years in the last insured place shall be pushed forward in turn to the insured places with 10 years to go through the formalities for receiving benefits; Those who have been insured for less than 10 years in various places shall go through the formalities for receiving benefits at the place where their household registration is located. In short, every insured person who has paid more than 15 years should receive a basic pension in one place. In addition, according to the old-age insurance policies of many provinces and cities in China, employees who work in this city and are not registered in this city have already participated in the local old-age insurance at the place where they are registered, and will no longer participate in the old-age insurance in this city; At the same time, if you participate in the old-age insurance in two places, the old-age insurance relationship of the repeated insured part is invalid.
