29 CFR § 1626.8 - Contents of charge; amendment of charge.
(a) In addition to the requirements of § 1626.6, each charge should contain the following:
(1) The full name and contact information of the person making the charge except as provided in § 1626.8(d) below;
(2) The full name and contact information of the person against whom the charge is made, if known (hereinafter referred to as the respondent);
(3) A clear and concise statement of the facts, including pertinent dates, constituting the alleged unlawful employment practices;
(4) If known, the approximate number of employees of the prospective defendant employer or members of the prospective defendant labor organization.
(5) A statement disclosing whether proceedings involving the alleged unlawful employment practice have been commenced before a State agency charged with the enforcement of fair employment practice laws and, if so, the date of such commencement and the name of the agency.
(b) Notwithstanding the provisions of paragraph (a) of this section, a charge is sufficient when the Commission receives from the person making the charge either a written statement or information reduced to writing by the Commission that conforms to the requirements of § 1626.6.
(c) A charge may be amended to clarify or amplify allegations made therein. Such amendments and amendments alleging additional acts which constitute unlawful employment practices related to or growing out of the subject matter of the original charge will relate back to the date the charge was first received. A charge that has been so amended shall not again be referred to the appropriate State agency.
(d) A charge that any person has engaged in or is engaging in an unlawful employment practice within the meaning of the ADEA may be made by or on behalf of any person claiming to be aggrieved. A charge on behalf of a person claiming to be aggrieved may be made by any person, agency, or organization. The written charge need not identify by name the person on whose behalf it is made. The person making the charge, however, must provide the Commission with the name and contact information of the person on whose behalf the charge is made. During the Commission investigation, Commission personnel shall verify the authorization of such charge by the person on whose behalf the charge is made. Any such person may request that the Commission shall keep his or her identity confidential. However, such request for confidentiality shall not prevent the Commission from disclosing the identity to Federal, State or local agencies that have agreed to keep such information confidential. If this condition is violated by a recipient agency, the Commission may decline to honor subsequent requests for such information.
(e) The person claiming to be aggrieved has the responsibility to provide the Commission with notice of a change in contact information so that he or she can be contacted when necessary during the Commission's consideration of the charge.
