Why Retailers Ask For Your Zip Code

Eye-opening post from the New York Times about why retailers ask for your zip code.Ask a merchant why they need your zip code, and they usually say “It’s for ‘marketing purposes.'”Indeed, it turns out your zip code, when combined with other purchase data, is quite revealing!
Stores want your ZIP code because, combined with your name from your credit card, they can use it to find out other information about you from commercial databases, like your full mailing address. They may even sell the information to data brokers, who sell it to other marketers.Clearly zip codes are useful data for retailers in planning new store openings and hirings. But providing this five-digit data also comes at the risk of receiving future junk mail campaigns!Even if you do not end up landing on direct mail lists or see personal targeting, the likehood of receiving bulk junk mail increases.Given a high enough density of existing customers in a zip code, a retailer will more readily consider launching a bulk mail campaign.Bulk mail campaigns (aka EDDM, or Every Door Direct Campaigns) are distributed to every address in a zip code (literally)! They are extremely cost-effective for marketers since they come with a huge discount per piece vs. first-class mail.Unfortunately, zip-code marketing remains a force to be reckoned with. Even though saturation campaigns are inherently wasteful and often end up annoying prospective customers.
But don’t forget … the power is in your hands
- It’s your choice! Don’t provide a zip code if you don’t want to.
- You can always ask whether a zip code is really needed to complete the transaction.
- If asked for your address, simply decline or say “Don’t put me on any postal marketing lists.”
