All officially made garments worldwide carry RN Registration Numbers on a small label with a bar code.
I have found a website which allows the public to find American manufacturers from RN's and vice versa but it do not apply outside the USA, this site is:
http://www.dir.ca.gov/databases/dlselr/garmregCMS.ASP
From this I determined that Speedos made in USA may carry the RN 43168 or New #: 19846.
These other numbers taken from my Speedos may help someone somewhere:
Thailand..........00300 85080
Sri Lanka.........00463 68321
China..............00420 63092
If anyone has any more genuine Speedo RN's they would like to add please contribute....
The RN's also relate to employee pay, conditions and health and safety, you may find this article relevant and interesting, re the Pakistan Garment factory Fire Investigation. (there is no suggestion that Speedos were made in this or any other factory involved).

I don't fully understand this subject, it is a crucial part of tracing fakers; if anyone knows more about it than me please teach us all.....
