Hi,
The service certificate is a confirmation from the employer about the continuation of employment of the employee in that particular organization. Whenever the employee needs any loan or is applying for higher education, etc., the employee will submit a written application to the employer. Based on the application, the employer or his representative will issue the service certificate.
The experience certificate is the letter given after the submission of the resignation by the employee or after completing the notice period and required formalities like handing over, no-due certificate, and exit interview formalities. Then, after relieving, an experience certificate is provided by the employer.
The service certificate is issued during the course of employment with the organization, while the experience certificate is provided after the closure of the employment, i.e., upon termination of the employee-employer relationship.
Regards,
Kamesh
