(CNN) The federal government hasn't issued a single stimulus check yet, but scammers are already trying to steal the money from Americans.

These criminal efforts are prompting the Federal Bureau of Investigation, multiple state attorneys general and other agencies to warn Americans not to fall for phone calls, texts, emails or websites that ask for personal or financial information in order to receive the $1,200 federal payment.

"If someone claims to be from the government with a check for you, it may be a phishing scam that is illegally trying to obtain your bank account or other personal information," New York Attorney General Letitia James said in a statement Saturday.

"Do not pay anyone who promises that they can expedite or obtain a payment or a loan for you," James continued. "If you are eligible for relief, you will not need to make any up-front payment or pay any fee to receive a stimulus payment."

Most Americans will receive up to $1,200 per person in coming weeks, as part of a historic $2 trillion stimulus package President Donald Trump signed into law Friday. Parents will receive up to another $500 for each child under age 17.
