Letter of Certification

A letter of certification (much like a letter of certificate) is written to verify information, usually in the context of applying for something. For example somebody applying for a visitor visa to a foreign country may obtain a letter of certification from their place of employment verifying their intent.


Somebody in the business world may use a letter to certify a percentage of ownership in a company, or a job applicant may use a letter from a friend or former employer as a reference – this is called a “Certification Letter of Knowing a Person.”


If there is something formal to certify, a letter of certification can be used.


If you were looking for a new job, you would request a letter of certification from your previous employer verifying that you did work for them in the past and in what capacity.


Starting to Write


Be specific with information, dates, and titles – for a certification to be of use it has to be accurate.


Include any relevant supporting documents as evidence that what is being certified is true.


Because these letter will invariably be used in a formal setting, write them in a formal manner.
