FCC Call Sign Districts — U.S. Mail Forwarding Addresses

U.S. Mailing Addresses for International Applicants

The following list provides U.S. mail forwarding services for international amateur radio examination applicants who do not have access to a U.S. mailing address.

These providers advertise international mail forwarding services. Applicants must register with their selected provider and obtain their own mailbox number before using an address.

What Is an FCC Call Sign District Number?

The district number refers to the numeral in a U.S. amateur radio call sign. For example, in K0RVE, K4ABC, and W6XYZ, the district numbers are 0, 4, and 6, respectively.

When the FCC initially assigns a call sign through the Sequential Call Sign System, the district number is determined by the geographic region associated with the applicant's registered FCC mailing address.

For example, if you would like a call sign containing the number 0, such as our VE team's call sign K0RVE, using a valid mailing address in Denver, Colorado (District 0) will result in an initial sequential call sign containing 0.

However, after receiving your initial call sign, you may apply for a Vanity Call Sign containing your preferred district number, regardless of your mailing address within the contiguous United States. The requested call sign must be available and meet the FCC's eligibility requirements.

Note: The prefix and suffix letters are assigned separately, and applicants cannot select an exact call sign through the initial sequential assignment process.

FCC Mailing Address Requirements

Under 47 CFR § 1.5 — Mailing Address Furnished by Licensee, FCC licensees are required to provide a mailing address for official correspondence.

In particular, 47 CFR § 1.5(b) places responsibility on the licensee to make any necessary arrangements to ensure that FCC documents and correspondence delivered to the registered address promptly reach the licensee or a person authorized to act on their behalf.

Accordingly, applicants and licensees should understand that:

• Providing a U.S. mailing address does not automatically guarantee successful delivery of FCC correspondence.
• Applicants must independently verify that their chosen mail forwarding provider can receive and forward official FCC correspondence.
• Licensees are responsible for maintaining appropriate arrangements to ensure the timely receipt of official communications.
• Using a third-party mail forwarding service does not transfer these regulatory responsibilities to VE Team Korea.

Applicants should also ensure that they provide a valid email address and comply with any applicable FCC contact information requirements.

Please review the FCC regulations carefully before selecting or registering a mailing address.

Third-Party Service Disclaimer

You must register directly with your chosen provider, obtain your own mailbox or suite number, and independently confirm that the provider can receive and forward official FCC correspondence to your country of residence.

VE Team Korea does not guarantee the accuracy, availability, reliability, delivery performance, or suitability of any third-party forwarding service.

Before using any of these services, applicants are strongly advised to carefully review all applicable terms of service, mailing restrictions, identity verification requirements, fees, international forwarding policies, and other conditions.
