Click the start menu button. Click settings. Then click accounts. On the left hand side, click sign-in options, then on the require sign-in drop-down menu, set it to never. Although, I wouldn't really recommend doing this as it is not secure. Thanks. Logged as an Admin and the above process works.
In 1983, the USPS changed its ZIP Code system to include the new ZIP+4. A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a small delivery segment such as a street, a city block, a group of apartments, or even an individual address that receives a high volume of mail.
1 If you are on the ZIP code field, only numerical values can be entered. If you try to enter a letter in the ZIP code field, it will not be entered as a value. ZIP code should be entered as a 5-digit number.  Phone numbers must be entered with three-digit area code, three digit prefix, and 4-digit number.
