What locale are you using with Bogus?

en_US

What's the problem?

I am getting a lot of invalid zip codes generated by Bogus. I have my locale set to en_US. I am wanting a 5 digit zip so I have "f.Address.ZipCode("#####")" but I have also tried it without any args or even with #####-#### but am still getting a lot of invalid zip codes. The zip codes seem to just be random numbers. As an example, the last zip generated was 95266 which is not a valid US zip code. I have verified the zip codes with the USPS to be sure.
