Facts about short codes go stale quickly. A code passes to a new company, a carrier stops supporting a kind of program, a lease price moves. If a page gets something wrong, name the page and the detail, and say where the correct version can be seen, ideally a CTIA document, a carrier notice or the sender’s own help page. Once an error is confirmed, the page is fixed.
A few requests cannot be handled from here. The site cannot tell you who sent a text you received, block a number on your line or take your number off a sender’s list. Replying STOP to the code ends the messages from any legitimate program, and your carrier can block a number for you. The major U.S. carriers also take suspected spam forwarded to 7726.
