Good question. The problem with the FCC ID search page is that the
search is broken. I haven't figured out exactly how it's broken, but
it often fails to find a known valid FCC ID, even when inscribed
completely. I assume you want to find something where you do not know
the FCC ID and only have the manufacturer and the model number. That's
a common problem for everyone which is aggravated by various vendors
not bothering to supply the FCC ID number on any of their literature
or web pages.
You can sometimes get lucky with a Google search using:
<http://www.google.com/help/features.html>
FCC equipment IDs example search: "fcc B4Z-34009-PIR"
Remember to put the word "fcc" before the equipment ID.
Even the example doesn't work, but it's worth a try.
Otherwise, start at:
<http://www.fcc.gov/oet/fccid/>
which will eventually lead you to:
<https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm>
There are really only 3 items of interest on this page that need to be
found. The "Grantee Code" which is the first 3 characters of the FCC
ID, and the "Product Code" which is the rest of the line. The last is
the "Show XX records at a time" at the bottom of the page. Change
that to 100.
If you don't know the 3 character Grantee Code, then go to:
<https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GranteeSearch.cfm>
For example, plugging in Cisco (for Linksys) will yield prefixes of:
LDK Cisco
PKW Cisco-Linksys
Q8G Cisco-Linksys
Q87 Cisco-Linksys
Most of the older Linksys stuff is under PKW and the newer stuff under
Q87. I think Q8G is dead.
Now, we go back to the search page and try PKW for the "Grantee Code".
<https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm>
Don't forget to set the "Show xx records..." to 100.
That yields 227 hits for Q87 (Linksys). Go down the FCC ID column
until you find the model number of the product. In most cases, the
model number will be obvious, but not always. A few vendors use
really obscure FCC ID numbers, which will require a model by model
search for the correct FCC ID. You will also find more than one hit
for a given model number.
Now, here's the part where the FCC ID search absolutely sucks. You
can't do a partial search by model number. For example, if you use
Q87 for the "Grantee Code" but insert just "WRT54G" for part of the
remaining "Product Code", the search finds nothing. The help page
shows that it should do a left justified substring search as in:
* Wild Card Right - When the search is performed the characters
entered into this field will be compared to the database using
a wild card on the right. For example, if the letter "A" is
entered then all records that start with the letter "A" in this
field will be returned (ABC, Apple, Able...).
However, it usually doesn't not work unless you know the tricks.
One trick is to put a "-" in front of the search. That's because the
"-" is significant and part of the FCC ID number. The problem is that
not every company uses the "-" so this trick doesn't work for
everyone. Using Q87 for the "Grantee Code" and "-WRT54G" for the
"Product Code", yields 32 hits. However, because of the left
justified nature of the search, manufacturers that imbed the model
number in the product code prefixed with some random garbage, cannot
be found in this manner.
The rest is just a matter of looking down the list and reducing the
number of hits to manageable size. There are a few other tricks but
this will do for now. I'll also spare you my opinion of the FCC and
it's general inability to do anything correctly.
