Example Community Support Letter:


Dear Representative, 

I am a resident or stakeholder of Frederick and am writing to express my utmost support for the Town of Frederick to have its own independent Zoning Improvement Plan (ZIP) Code. Specifically, I sincerely request that Congress provides favorable consideration for H.R. 3095, which would grant Frederick and several other jurisdictions across the nation independent ZIP codes if the bill is passed.

We acknowledge that the Town of Frederick currently shares ZIP Codes 80504, 80516 and 80530 with neighboring jurisdictions. However, the Town of Frederick has quickly expanded to one of the fastest-growing Towns in Northern Colorado. Establishing an independent ZIP code for the Town is vital to Frederick’s growth. Towns and cities without their own unique ZIP Codes often face a range of negative consequences.

These include reduced economic development opportunities, loss of sales tax revenue, elevated insurance premiums, and complications with tax remittance and commercial licensing. Additionally, public safety is often compromised, as emergency responders may experience delays or confusion, leading to slower response times. This is a particular concern for our community, as there have been instances where first responders have mistakenly gone to the wrong streets due to ZIP Code issues.

In Frederick, over 4,000 households are assigned to the Longmont ZIP Code (80504), and more than 2,000 households have the Erie ZIP Code (80516). This situation has the potential to cause a conservative estimate of $1.5 million in lost sales tax revenue, as purchases made by Frederick residents are allocated outside our town.

The lack of an independent ZIP code also causes confusion with voter registration and elections, impacts Frederick efforts to build a community identity, and interferes with emergency response and public safety activities.

Understanding that the lack of a definitive ZIP code impacts the Town of Frederick identity, economic culture, and quality of life, I sincerely request Congress to provide favorable consideration for the bill.
