Drug Enforcement Administration (DEA) is warning pharmacists and doctors of fraudsters impersonating DEA agents and demanding sensitive information or payment. Legitimate DEA agents will only communicate with individuals about investigations or legal actions in person or via an official letter. Scam tactics may include using an urgent and aggressive tone, threatening arrest, referencing National Provider Identifier numbers and/or state license numbers, and more. Individuals receiving a call from someone claiming to be with DEA are encouraged to report the incident to the Federal Bureau of Investigation.
