A Verification To Whom It May Concern Letter is a formal document that verifies a specific individual and supports the reputation of the person being verified. The letter, addressed to whom it may concern, should outline the details of the person’s identity and other relevant information. This includes the name and contact information of the signed off letter writer, their relationship or association with the verified individual, their qualifications to make such attestation and any other information provided in regards to the verification. Ultimately, this type of letter serves as proof of a person’s identity and is an invaluable tool for verifying credentials, providing background checks and referrals.
