History of the 845 Area Code

Understanding the history of this telephone code helps explain why it exists today.

Creation of the Area Code

Before the mid-1990s, much of this region used the 914 area code.

As population growth increased and demand for telephone numbers expanded, telecommunications authorities determined that additional numbering resources were needed.

The 845 code was introduced in 2000 through a geographic split.

Why the Split Happened

Several factors contributed to the change:

• Growing population
• Increased business activity
• Expansion of mobile phone usage
• Internet and fax line growth
• Demand for additional telephone numbers

The split allowed sufficient numbering capacity for future growth throughout the region.

Introduction of Overlay Code 329

As telecommunications needs continued to expand, an overlay area code was later introduced.

This means both 845 and 329 can serve the same geographic region. New phone numbers may receive either area code depending on availability.

What Time Zone Does the 845 Area Code Use?

The entire coverage area operates within the Eastern Time Zone.

Standard Time

During standard time periods, the region follows:

• Eastern Standard Time (EST)
• UTC -5 hours

Daylight Saving Time

During daylight saving periods, the region observes:

• Eastern Daylight Time (EDT)

Business Communication Considerations
