After learning about Equifax's failure to keep sensitive financial data of over 100 million Americans secret, I am considering a security freeze on my credit record. I found the relevant pages of the three main credit reporting agencies websites, but they are only suitable for US residents. I can find no information on their websites about freezing credit records from overseas. Additionally, the forms all contain "State" and "ZIP Code" as mandatory fields, and do not permit entering a foreign country as part of the address.
Can US citizens living overseas place a security freeze on their credit records back in America, and if so, how do we do that please?
