Zip Codes Unofficial
This file was originally based on the 2010 Census TIGER file of Maryland Zipcodes. Subsequent investigation found that the zipcode boundaries were mostly incorrect. The IT department used the publicly available USPS online zip code lookup tool to look up individual addresses along the suspected zip code borders. Using the results from the USPS, the boundary lines were adjusted to reflect current zipcode boundaries to the best degree possible.It is important to note that the county government is not responsible for assigning Zip Codes. USPS does not publish official Zip Code maps. Becuase of Zip Codes importance to so many county and citizen functions though, the IT department has created this layer to be used only as a reference. The USPS may make changes to boundaries at any time with no notice to the county, rendering this map out of date.This layer was created in July of 2019 and has not been updated since.
