New FCC ID format could make searching IDs difficult

Starting tomorrow, May 1st, 2013, the FCC will begin issuing new grantee codes as five character codes. Existing 3 character codes will still be valid, but new codes as of tomorrow will be in the 5 character format.  An earlier post describes why the change to the 5 character system. See FCC running out of Grantee codes.

Now that grantee codes could be both 3 character and 5 character, for those who use the Equipment Authorization Database search to lookup FCC IDs, it could be difficult at first getting use to the new system. How do you know if it’s a 3 character code or a 5 character code just by looking at the ID?




Here’s a tip.

3 or 5 character grantee code? To tell;

1. if it starts with a number, it’s a 5 character code

2. if it starts with a letter, it’s a 3 character code.

The use of 1 and 0 is excluded, to avoid confusion with the letters i and o.

I don’t know if this visual would work the same for you, but what I do is picture a telephone keypad, it kind of looks like a # symbol with the number 5 in the middle;



# = Number so 5 starts with number. Silly, but it works for me.

So for the example above; 2AA56 is the 5 character code (starts with a #) and G77 is the 3 character code (starts with a letter).

Jamming employee cell phones can cost

The FCC issued several notices of apparent liability, in amounts exceeding $120,000 for illegal cell jammer use.

In the referenced Notice of Apparent Liability (NAL), anonymous complaints resulted in immediate investigation of companies employing cell jammers to block cellular communications. Upon investigation by FCC field agents, the companies were found to be using broadband cell signal jammers, illegally shipped from overseas. In one case it was noted the jammers had been installed following a "near miss" potential for an industrial accident, attributed to employee phone use on the job. The managers at the work sites confirmed that the jammers were installed to prevent employees from using cell phones while working.

The problem is noted that these jammers don't discriminate, blocking all cell traffic in and around the area including necessary emergency communications such as 9-1-1 calls.

In each of the cases, the jammers were surrendered to the FCC agents, along with any spare backup jammers. The FCC agents confirmed that the cell band interference had ceased after the jammers were removed.

In each case, the maximum forfeiture amount allowable by statute was proposed, however, the total amount was revised downward by 25%, due to the immediate voluntary surrender of the illegal jammers. It was acknowledged that the Commission has authority to confiscate illegal devices, however, the Commission recognizes the benefits of the voluntary cooperation, and would like to encourage similar conduct in the future.
