Can AT&T look up an old phone number
I need to find an old phone number i had in 2007. i know thats a long time ago but i need this phone number so that i can recover my federal employer id number. the IRS has to have the phone number to look up the business that was associated with it. i really need to find out what my FEIN is because you are only given one in your life and i now own my 2nd company but i dont have my FEIN to link which i need to get business loans and bank accounts. is there any way AT&T can tell me what my number was if i give them all identifying info, the address, and the area code with first 3 numbers?
