The boundaries of Littleton's city limits, like many cities, are irregular and don't always follow landmarks such as paved streets. The Google Map below shows the approximate boundaries of the Littleton city limits. To check whether an individual address is in the city limits, use the Address Wizard.
Just because the mailing address says "Littleton" doesn't mean that the address is actually within the Littleton city limits. Check out the Littleton ZIP Codes page to find out why.
