The Town of Lansing, including the Village, is divided by into five Zone Improvement Plan (ZIP) Codes, including the ones for Lansing, Ithaca, Locke, Groton, and Freeville. While most people consider their mailing address to be the same as their actual address, that isn't necessarily the case. As far as the United States Postal Service (USPS) is concerned, you only live in Lansing if your ZIP code is 14882.
The largest number, 1,400, of tax parcels in Lansing are assigned the Ithaca ZIP code (14850). The Lansing ZIP code (14882) follows with 1,130 parcels. 260 are in Groton (13073), 73 in Freeville (13068), and 66 in Locke (13092). While it might make sense to at least fold Lansing households with Groton, Locke, and Freeville addresses into 14882, Ithaca Postmaster William C. Hrynko, Jr. says doing so would be difficult. "That is minimal as far as impact on the number of employees," he says. "The biggest issue would be territorial. When the ZIP codes came out in 1983, their purpose was basically for efficiency. It didn't have any boundaries on maps for counties and townships."
