12 FCC ID: AAAnnnnnnnnnnnnnn AAA: is Grantee Code from FCC. Need to get the Grantee Code from FCC:nnnnnnnnnnnnnn: is from ManufacturerGet grantee code from web site“https://gullfoss.fcc.gov/prod/oet/index.html”Cost: $50 (one time only)The FCC ID number must be on all Certified DevicesThe FCC ID is a string of characters that may be from 4 to 17 characters long.It may contain any combination of capital letters, numbers, or the dash/hyphen character. Characters 4 through 17 are completely up to the applicant.The first three characters, however, are the "grantee code," a 3-character code assigned by the FCC to a particular applicant (grantee).Any application filed with the FCC must have an FCC ID that commences with an assigned grantee code.
13 Obtaining an FCC Grantee Code Procedures regarding online grantee code assignments and payment information:Go to: https://gullfoss2.fcc.gov/prod/oet/cf/eas/index.cfmFor first-time filers, go to Miscellaneous on the left side of the page.Click on GET FRN. Follow Directions. WRITE DOWN FRN!Go back to: https://gullfoss2.fcc.gov/prod/oet/cf/eas/index.cfmGo to Filing Options > Grantee Registration. Follow Directions. WRITE DOWN GRANTEE CODEThe client should retain the grantee code assignment page. This page provides the date that the grantee code was assigned.Payment (one-time $50.00 fee) via online credit card is recommended as the quickest payment procedure. The payer should retain a copy of the acknowlegment of the payment. If for some reason the online payment fails, the payment (via check; money order; wire transfer; or credit card) and Form 159 should be submitted to Mellon Bank AS SOON AS POSSIBLE - within a day or two of the date the code was assigned, and certainly NO LONGER THAN 15 days after the code assignment. It is important to allow enough time for the payment to clear through Mellon Bank before the 30-day time limit.
