To reach Social Security, you would want to dial +1 8007721213 on your phone. If you use TTY equipment, then you would want to call +1 8003250778. Note that Social Security will never call you without letting you know ahead of time. If you get a phone call with the CID showing one of these two numbers, and they want your Social Security Number – Do NOT give your SSN. Instead, tell them that you will call back, and call the numbers located on https://www.ssa.gov/agency/contact/phone.html. This is the location I received the above two numbers.
