Cook County alone contains 167 of the state's 1,396, more than four times the next county.

Sources: ZIP boundaries and codes from the U.S. Census Bureau 2020 ZIP Code Tabulation Areas (public domain). Place names from GeoNames, licensed under CC BY 4.0. Census geography has been simplified for display. This is not an official Census Bureau product, and the Census Bureau does not endorse it.
About these boundaries: ZIP Code Tabulation Areas approximate the area a ZIP code covers, but a ZIP code is a set of delivery routes, not a shape. Around 4,800 delivery ZIP codes have no boundary at all, being PO-box-only, single-building or military codes. Shaded ZIP areas and outlines are approximate geographic references. They are not legal property boundaries, municipal boundaries, tax districts, voting districts, school zones, emergency response areas, or official USPS delivery boundaries.
One city, then everyone else. Chicago's 56 ZIP areas are 6.2 times the next largest place, the steepest drop-off of any large state. Peoria and Rockford follow with 9 each, Springfield has 8, East Saint Louis 6 and Aurora 5. That shape does not show up in the usual measure. The five biggest places hold just 6.3% of Illinois between them, which reads as a dispersed state. But the gap between first and second is what actually defines the map.
Cook County is the real centre. With 167 ZIP areas, Cook County holds nearly 12% of the state on its own. DuPage follows with 37, Will with 30, Champaign with 29 and Lake with 28. Illinois has 102 counties, and 34.7% of its ZIP areas cross a county line, so the table's primary county column shows the county holding most of each area's land rather than its only one.
Numbering. Illinois uses 29 three-digit prefixes, running 600 to 620 and then 622 to 629. Only one prefix inside the range, 621, has no ZIP areas anywhere in the country. That is the mark of numbers used entirely for PO boxes, single-building addresses or military mail, none of which the Census draws.
Size. The largest Illinois ZIP area is 61944 around Paris at 263 square miles. The smallest is 61331 at Lee Center, twenty-eight thousandths of a square mile. The median is 31.5 square miles, and the state's ZIP areas cover 55,490 square miles of land in total. Of the 1,257 place names on the map, 1,218 hold exactly one ZIP code.

Frequently Asked Questions
Illinois has 1,396 ZIP code areas on this map, fifth most in the country behind Texas, Pennsylvania, New York and California. The figure counts ZIP Code Tabulation Areas, the Census Bureau's drawn approximation of each ZIP code, and it is the number of shapes you can click, sort and color here. The number USPS quotes is higher, because its count includes ZIP codes with no area to draw: those used only for PO boxes, those assigned to a single large building, and military mail codes. Roughly one delivery ZIP code in eight nationally has no boundary for that reason, so it exists in address databases but appears on no map.
Illinois ZIP codes use 29 three-digit prefixes: 600 through 620, then 622 through 629. The first three digits identify the mail processing facility serving everything beneath them, so the prefix is a rough regional guide. 606 is Chicago proper, 600 to 605 the suburbs, 615 Peoria, 617 Springfield, 620 the Metro East across from St Louis and 629 the far south. The single missing prefix, 621, has no ZIP areas anywhere in the country, not just none in Illinois. With 1,396 areas across 29 prefixes, Illinois averages about 48 ZIP codes per prefix. The range itself is narrow, 60002 to 62999, so Illinois packs 1,396 areas into fewer than 3,000 consecutive numbers.
Chicago, with 56 ZIP code areas, 6.2 times as many as Peoria or Rockford, which tie for second with 9 apiece. That ratio is the widest of any large state: for comparison, Houston leads Texas by only 1.6 times and Los Angeles leads California by 1.6. Springfield has 8 ZIP areas, East Saint Louis 6 and Aurora 5. Despite the dominance, Chicago is only 4% of the state's 1,396 areas, because Illinois has 1,257 distinct place names and most of them hold a single ZIP code each. At county level the concentration is starker still: Cook County holds 167 ZIP areas, nearly 12% of Illinois, and more than four times DuPage County's 37.
Illinois ZIP codes run from 60002 to 62999. The low end is in Lake County near the Wisconsin border and the high end in the far south near the Ohio River, so sorting the table on this page by ZIP code walks the state roughly north to south. The range is almost continuous. Only prefix 621 is missing, and it carries no ZIP areas anywhere in the country. Sorted by land area instead, the same 1,396 rows run from 263 square miles around Paris down to twenty-eight thousandths of a square mile at Lee Center. The state's 1,396 ZIP areas cover 55,490 square miles of land, spread across 102 counties.
Because a USPS ZIP code is a set of delivery stops along carrier routes, not an area, and some have no meaningful area at all. A ZIP assigned to a single office building, one used only for PO boxes at a post office counter, or a military APO or FPO code has no territory to draw, so the Census Bureau creates no ZIP Code Tabulation Area for it and it appears on no map, this one included. Illinois shows the effect at prefix level: the whole 621 block sits inside the state's range with no drawable ZIP areas in it. Nationally about one delivery ZIP code in eight has no boundary.
No, and no ZIP code boundary anywhere is official. The Postal Service does not publish ZIP codes as polygons, because it does not maintain them as areas. They are routing paths. Illinois's 1,396 shapes are Census Bureau ZIP Code Tabulation Areas, as are those on every other ZIP map: groups of census blocks sharing a dominant ZIP code. The fit is close inside Chicago and looser across the central and southern farmland. Use these boundaries as a geographic reference, never as a legal one: they are not property lines, city limits, tax districts, school zones, voting districts, emergency response areas or official USPS delivery boundaries.
Yes. Open all 1,396 areas in the Ultimaps editor, color them, then export. The free file is a watermarked PNG. SVG, PDF or a clean image need Pro. What this page deliberately does not offer is a printable reference sheet with all 1,396 codes labelled, and that is a limit of scale rather than of file format: five-digit numbers cannot be placed legibly at state size when 167 of them fall inside Cook County alone. For a printable overview of the same geography, the three-digit prefix map is the readable version. Illinois has 29 prefixes, and they label cleanly at any print size.
Click any ZIP area on the map to select it, or open the map in the editor to work with all 1,396 at once. There you can fill areas by category (sales territories, service areas, delivery zones, franchise regions) or by value, which shades each area on a scale from a number you supply. Data keyed by ZIP code matches straight onto the map with no geocoding step. Bear in mind that 34.7% of Illinois ZIP areas cross a county line, so a territory defined by counties will not translate cleanly into one defined by ZIP codes. ZIP codes with no drawn boundary cannot be shaded, so PO-box-only or single-building codes in your list are reported as unmatched rather than dropped silently.
