Need a quick link to the FCC's RENEWAL and MODIFICATION site

https://wireless2.fcc.gov/UlsEntry/licManager/login.jsp

The requirements are that you MUST have:

Your 10-digit FCC Registration Number (FRN). (It's printed on the bottom of your existing license.)

A valid password for the FCC site (there's a link on the page to initiate a password reset, but it's usually a delayed response via email.)

Once logged in, you're presented with a list of the FCC licenses affiliated with your FRN.

Click on the one that needs to be modified or renewed.

On the next page, the details for the selected license are listed. On the far right side is a link to click for MODIFICATION or, if you're within the renewal period, a RENEWAL.

When you're done, be sure to log out (log out link usually in upper left corner) and exit the browser.

Modifications & Renewals usually take 24-48 hours for processing before the updates appear on the website.
