Private Reference, Not a Custodian. Concord Residents Directory cannot retrieve records, certify copies, confirm who lives at a location, or change an office roll. Requests for those actions belong with the agency that keeps the record. For an emergency, call 911. If you believe someone is stalking or harassing you, contact local police.
