Glossary and Definitions ...
- Area Code Overlay
- An Overlay refers to the situation in which two (or more) area codes (eg- 410, 443, 667) serve the same geographic area. In the case of Andora Acres, area codes (443, 667) are the Overlays for (410, 443, 667).
The Overlay is necessary when the geographic area requires (or in the future will need) more phone numbers than can be provided by a single area code.
When an Overlay is present, 10-digit dialing becomes necessary for all calls. There are different types of Overlays, with each type having its own characteristics and dialing requirements.

- GNIS Codes
- The function of the U.S. Board on Geographic Names (BGN) is to establish uniform names for geographic features (eg- communities, mountains, lakes, rivers, streams, etc). The BGN was created to address the problems caused by spelling and naming variations. BGN–accepted names are kept in a database called the Geographic Names Information System (GNIS), which is operated and maintained by the U.S. Geological Survey (USGS).
A unique and permanent identifier has been assigned for each feature in the GNIS database. These names and identifiers are definitive.
Andora Acres has been given the GNIS Feature ID of '589062'. Click here to see the GNIS Record for Andora Acres.
