Other members have their handle and one alias and that's it.  I  went to "My TER" to check and found no number associated with my account.

....but it's of no real use. If you have a VIP membership that you pay for and decide to cancel you will be asked for your "member number".  I believe that's what it's called.  If you have written reviews then when you go to My TER and click on "My Reviews" then click on "View" your TER number will be at the top of the review and it will be labeled as your member number or ID  number. Not the provider's number. There will be a number for you.

I believe in "Classic:" TER you can find your TER number when you go to account manager. For some reason it's not listed in "Account Manager" on the newer version of TER. (The newer version is most likely the one you are using.)

Hope this is helpful.

I hear that you can use this number to reveal secrets of the universe.

Take my number, for instance:  It is 524719.

Now, summing those six digits brings me to the number 28, a very significant number for me, by the way.

Summing the digits of 28 = 10, another very auspicious number, and then summing those two digits equals 1, which makes me the number 1 person in the universe, which also makes sense since I am Jewish.

Who said that the membership ID didn't have any meaning?

Got It

Thanks to one and all.
