The True Origin: International Use and Placeholders
The number 10000 is far more likely to be an active postal code in a different international postal system than in the US.
- Placeholder Use: In some databases, ‘10000’ is used as a generic, non-specific placeholder for the state of New York, similar to how ‘90210’ is sometimes used for the Los Angeles region.
- International Postal Codes: In several countries, the postal code 10000 is an actual, active code. For example, 10000 is the postal code for the central or downtown area of Prague, Czech Republic.
Why Your ZIP Code is a Security Concern
While the ZIP code itself is considered public information, scammers often try to steal it because it can be used for financial fraud.
- Credit Card Verification (AVS): Gas pumps, online retailers, and other self-service merchants use your ZIP code to perform an Address Verification Service (AVS) check on your credit card. If a fraudster steals your card number, they need the correct ZIP code to bypass this security layer.
- Neighbor Phishing: Scammers might use a generic ZIP code to run a localized online scam (phishing texts or fake delivery notices) that targets a broad area around a major city.
Safety Tip: Never give out your full address, phone number, or ZIP code in response to an unsolicited text message (Smishing) or phone call, especially if it asks you to click a link to verify a purchase or delivery.
