- Area Code Overlay
- An Overlay refers to the situation in which two (or more) area codes (eg- 587, 780) serve the same geographic area. In the case of Akinsdale, area code (587) is the Overlay for area code (780).
The Overlay is necessary when the geographic area requires (or expects to 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, even if local. There are different types of Overlays, with each of the different Overlays having its own characteristics and dialing requirements.

- Canadian Postal Code (FSA & LDU)
- The Canadian Postal Code is a 6-character alpha-numeric code that is used to improve the efficiency and aid the automation of mail sorting and delivery.
The first three characters are called the 'Forward Sortation Area' (or the 'FSA') and indicates a geographical area within Canada. The first and last characters are 'A' through 'Z' and the middle character is always numeric ('0' through '9'). The FSA for Akinsdale is 'T8N'.
In an urban area (such as Akinsdale), the LDU can indicate a city block, a single building, a complex of buildings or a high-volume mail receiver (such as a payment processor). Since there are so many possibile LDUs, we only show the 'FSA'.
