| <4> | ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a community (such as Hyannis). When looking for a ZIP Code, whether Hyannis or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |

| <6> | If we found a location and have questions about the accuracy of our information, we will simply say that the marker is 'in the vicinity'. We are not confident about the location and the position of our marker is only a rough guide. If we have too many doubts about the location, we will not include it in our database. |
