At TxtDrop we care about your privacy. If you wish to block your number from TxtDrop.com users and our network of free text messaging sites, please enter your 10 digit mobile number below. You should receive a text message within a few seconds that contains your 5 character confirmation code. On the next page you will be asked to enter this confirmation code. If you do not receive a text message, that means we are having problems sending messages to your phone, so you should already not be able to receive messages from our users. Once your number is blocked you can confirm by trying to send yourself a message.
