Claim Your Amateur Callsign Subdomain

This guide explains how to request a callsign-based subdomain under ampr.org (for example, ki5qkx.ampr.org).

Requirements

You must have a verified amateur radio callsign in the Portal.
Callsign-based subdomains are automatically approved once the callsign is verified.
Non-callsign subdomains can be requested, but they require manual review and are rarely approved without strong justification.

Verify Your Callsign

Sign in to the Portal.
Go to Account → Call signs.
Click Verify next to your callsign.
If there is no Verify button, that callsign is already verified.

Request the Subdomain

Go to DNS → My subdomains.
Click Request a subdomain.
Select ampr.org as the domain.
Enter your subdomain (usually your callsign, without .ampr.org). Example: ki5qkx.
Submit the request.

What Happens Next

If the subdomain matches one of your verified callsigns, it is approved and assigned to you automatically.
If it does not match a verified callsign, a ticket is created and a staff review is required.

Tip

If you are planning to add multiple DNS records, request a subdomain rather than claiming a single DNS record. Subdomains let you manage all records under your namespace.
