Got a letter from 92799?
Many people look up 92799 after receiving mail postmarked or return-addressed there. In the reference dataset 92799 is a Santa Ana, California ZIP code in Orange County. A ZIP code identifies where mail is processed or delivered, not who sent it, so the ZIP alone cannot tell you the sender.
How to identify the sender safely
- Read the return address, company name and any account or reference number printed on the letter.
- If it claims to be from a bank, government agency or court, contact that organisation using a phone number or website you find independently, not one printed in the letter.
- Be cautious about letters that ask for payment or personal details. The U.S. Postal Inspection Service investigates mail fraud and explains how to report suspicious mail.
