United States Post Office Postal Information

Postal information

Many of the cases private detectives are involved with involve address searches, telephone number lookups, and reverse searches.  Having knowledge of post information will help speed up the search process. Following is information related to postal matters:

Canadian Postal Service – Information on Canadian postal rates, services, area codes, zip codes, post office locations and more. In English and French

Canadian Postal Code Lookup Service – Using the form to enter the full Street Address, City, and Province for the Canadian mailing address you want to find.
