The Region field is on the MPD Tab, and the Regions Tab is in

The Regions Tab:

Defining Regions
| 1. | You can define a region as you work with individual contacts. As you add contacts, if you associate any of them with a region, TntMPD will automatically associate with that region all existing and new contacts who share that city and postal code. |
| 2. | You can also manually create—or modify—regions in the area. |
Associating a city, state/province, and/or postal code with a Region
| • | In the Options dialog box (), select the Region to which you want to add a city, state and/or postal code. |
| • | Press . Enter the city, state, and postal code. If you do not specify a postal code, all contacts in that city will be in the same region. |

Dividing One City into Multiple Regions
A city/postal code combination can only be in one region. However, the same city and different postal code could be in a different region. In New York City, for example, you could have a region for Brooklyn, Queens, Manhattan, etc., all of which are addressed to “New York, NY”, but have different postal codes.
Region quick notes
| • | If you use zip codes to define regions, you can choose how many digits to broaden that lookup. (For example, zip/postal code “starts with” 84; all communities whose zip codes start with 84 will be associated with that region.). This will also work with alpha zip codes (common in British Commonwealth countries). |
| • | A city/zip code combination can only be in one region. If you are working with a contact and change that contact’s region, all other contacts who live in that city will automatically be reassigned to the new region (after you confirm the region change). |
| • | If you add a new contact whose city & postal code matches an existing region, the new contact will automatically be assigned to that existing region. |
| • | If you try to add a city to a region and that city is already assigned to a different region, TntMPD will ask you if you want to change the region. |
| • | You cannot assign a contact to a Region if they do not have a city. |
| • | You can assign a city/state (with no postal code) to a region and assign that same city/state (with a specific postal code) to another region. |
| • | The Region field is intended to help you group multiple contacts from one city—or even one section of a city—to facilitate visits to those contacts. |
| • | Regions are created automatically as you add them to the region field. |
| • | Once a region is created, adding a new contact with the same postal code will cause that contact to be associated with that region. |
| • | Another option is to break them down by useful geographic areas that are relevant to you such as states or provinces. |
| • | A contact can only have one Region. |
