How to Verify Your Downers Grove, IL ZIP Code

To ensure you are using the correct ZIP code for any given address in Downers Grove, IL, it's always best to verify. The most reliable methods include:

The Role of ZIP+4 Codes

Beyond the standard five-digit ZIP code, the USPS also utilizes ZIP+4 codes. These consist of the original five digits followed by a hyphen and four additional digits (e.g., 60515-XXXX). The ZIP+4 code provides a more granular level of detail, further refining mail delivery to specific blocks, buildings, or even individual mail routes. While not always necessary for standard mail, using the full ZIP+4 can further improve delivery efficiency, especially for businesses with high mail volumes. — JuJu Smith-Schuster: Stats, News & Career
