Chicago's post office listings spread across the city rather than clustering in one spot. The 60625 zip leads with seven locations, followed by 60615, 60618, and 60643 with five each, then 60609, 60614, 60647, and 60649 with four apiece. That pattern shows up across 159 total listings for this category, so wherever you are in the city, a branch usually sits close by.

Most entries here list a phone number, and the majority also link out to a website, so you can typically call ahead or check hours online before making a trip. Sponsored tags would mark any paid placement in this category, and none currently appear, so the order you see reflects plain directory data rather than promotion. If you run a post office location and notice a wrong number or a dead website link, you can claim the listing and correct it yourself, which helps the next person searching a busy zip like 60625 reach you on the first try instead of hitting a bad number.
