Mapping Illinois
Illinois runs from the Chicago metropolitan area in the northeast to smaller cities and rural areas farther south. Springfield and Carbondale provide reference points away from Chicago, helping make a statewide map useful for more than one market.
The three-digit PDF is a clear starting point for a statewide overview. Use the five-digit tool when you need to distinguish Chicago-area ZIPs, central Illinois sales patches or southern service coverage. You can group ZIP areas into your own territories without suggesting that those colours represent counties or city limits.

Illinois ZIP map questions
Is the free Illinois ZIP code map 3-digit or 5-digit?
The free PDF and the map preview show three-digit ZIP prefixes, main roads and place names. A prefix groups codes by their first three digits. To colour individual five-digit ZIP areas, open the separate Illinois map in our online colouring tool.
Can I try the five-digit map before buying?
Yes. Load the map and try colouring areas, adding a key and changing the labels before buying access. Saving and downloading your finished map require the relevant map access. The free three-digit PDF download on this page is separate and does not require colouring-tool access.
Can I edit the map artwork?
The free PDF is a vector map for a clear view at different sizes. For supplied editable artwork and other formats, follow the editable-artwork section on this page. Check the available files and licence before buying; map files are separate from access to the online colouring tool.
Can I combine Illinois with other states?
Yes. Open the state chooser and select up to three states that form a connected group. Each state must connect to the group, but does not have to touch every other selected state. Load and customise the combined map before buying. You can buy the selected states together, one state or access to all 50. Alaska may be added separately within the same three-state limit.
How should I prepare ZIP codes in a spreadsheet?
Keep the ZIP column as text with all five characters. Some US ZIP codes start with zero: for example, 02108 must not become 2108. Keeping the column as text prevents a spreadsheet from removing a leading zero before you import your codes into the colouring tool.
Are ZIP areas the same as counties or town boundaries?
No. ZIP codes are used for mail delivery; counties and municipalities are different geographies. Our colouring-tool dataset contains 1244 mapped ZIP areas for Illinois. That is a count of areas in this map, not a total of every USPS delivery code, PO Box or unique organisation code.
