Yes. This website displays the standard 5-digit base postal codes. For actual mailing, a hyphen followed by a 4-digit extension (e.g., 90001-1234) can be appended to identify specific street segments, buildings, or post office boxes.
Can the phone numbers generated here be used for real calls?
No. The numbers use real regional area codes, but the subscriber numbers are randomly generated mock sequences. They are intended for developers to test input validation and UI formatting in application workflows. They cannot make or receive actual calls.
How frequently is the postal database updated?
Our database is periodically synchronized with official postal releases (like the USPS directories) to ensure that base codes and local district mapping rules remain accurate and up-to-date.
