To verify a Certificate of Employment, start by checking that the document is on the company’s official letterhead and includes the authorized signature or seal. 

Make sure the employee’s name, job title, and employment dates match the information on their resume. It’s also a good idea to contact the HR department of the issuing company directly to confirm the details.
