Used stamps exchanges.

I received a letter with 100 stamps signed "regards from Chile" posted on August 8 2022 with an ID number of CL-265. When I tried to register it I get an "ID is not Correct" message. Please help

I have recreated and registered CL-265

I am sure it has expired Mark. I guess this one will too

Hi Sharon, unfortunately I don't have the answer for you, just interesting that I received CL-247 a couple of days ago for which I also get an incorrect ID message. Mine seems to have been posted in January (!) though, so it's probably expired on the system.
Cheers,
Mark
