To find out your ZIP code, simply visit a website such as WhatIsMyZip.com, which uses GPS to identify user ZIP codes or postal codes. You can also type in a street address to find out that location's ZIP code.
You can also visit the US Postal Service or Canada Post website to learn ZIP codes for residential and corporate addresses. Alternatively, you can use Google Maps on your smartphone to pinpoint your current location and bring up your ZIP or postal code, as well. If you do not have access to a computer or smartphone, you can check the address on physical mail that has been delivered to your home.
