Circle is measured from where you first press; Lasso follows your outline. The switch under Add and Remove decides which ZIPs count: Touching (any ZIP the shape touches), Center in (the ZIP's center point is inside) or Fully in (the whole ZIP is inside). For an exact distance, type a ZIP above and press Radius.
To leave out PO Box or single-organization ZIPs (a company, university or government office), or to keep only those, uncheck the others under ZIP types in the list panel.
The dotted grip on each box moves it: click or tap the grip to fold the box away, drag it to put the box somewhere else.
About ZipZoomer: what it does, the data it uses, and answers to common questions.
ZipZoomer is a quick first step for a USPS Every Door Direct Mail (EDDM) mailing: see the ZIP codes around your shop on one map, check how many people live in them, and settle the area before you pick carrier routes. EDDM works route by route inside each ZIP code, so a ZIP list is your checklist for the USPS tool.
The map above opens on a 5-mile radius around 64105 in Kansas City. Search your own ZIP code, or draw the neighborhoods you want to reach.
The EDDM tool shows routes for the place you search, which makes it slow to compare areas or see where one ZIP code ends and the next begins. ZipZoomer shows every ZIP code in the area at once, with outlines, county lines and the population total, and lets you try a 3-mile and a 5-mile area side by side in seconds. Once the area is settled, the list tells you which ZIP codes to open in the USPS tool, and the 5,000-piece-per-ZIP Retail limit tells you which ones might need two days.
A carrier route is one mail carrier’s set of addresses inside a ZIP code. ZipZoomer’s outlines are the Census Bureau’s 2020 ZIP Code Tabulation Areas, which follow ZIP codes closely but are not USPS route maps. Use ZipZoomer to choose the ZIP codes and the general area, and the EDDM tool for the final route choice and exact counts.
The population in ZipZoomer’s panel counts people (2020 Census), not mailboxes. Households are fewer than people, and the EDDM tool counts residential and business deliveries on each route. Use the population to compare areas, and the route counts to order prints.
You choose routes, and selecting every route in a ZIP code covers it. With EDDM Retail, a mailing can be 200 to 5,000 pieces per day per ZIP code, so a large ZIP code may need to be split across days or sent through EDDM BMEU.
Not for EDDM Retail, which uses a USPS.com account. EDDM BMEU, for larger mailings, needs a bulk mailing permit and a Business Customer Gateway account (checked October 26, 2026).
PO Box and single-organization ZIP codes, which cover post office boxes, companies or campuses rather than neighborhoods. Uncheck them under ZIP types and every radius and drawing skips them.
No. It counts people. Each household gets one piece, so the delivery counts in the EDDM tool are what to print and pay for.
No. ZipZoomer has no link to USPS. Use the list as a checklist while you choose routes in the EDDM Online Tool.
