How to find the right ZIP
- Look up by full address. The USPS “Look Up a ZIP Code” tool is the authoritative source.
- Don’t rely on city names. Dallas ZIPs cover parts of several suburbs, and suburban ZIPs often cross city and county lines, so a mailing address can say “Dallas” even when the property sits in another city.
- Use ZIP+4 for accuracy. The extra four digits help route mail precisely.
- Check PO Box and unique ZIPs. These aren’t for street delivery to homes.
