When a tipster calls the Crime Stoppers telephone line, they are first given a code number and they are prompted not to disclose their identity at any time. The tipster then uses that same code number for all subsequent communication with Crime Stoppers. The program does not subscribe to call display anywhere in North America and the identity of the caller, beyond gender, is never known. In the Crime Stoppers file that is created, the caller is referred to as "the tipster" and not "he or she" which would then disclose the gender of the tipster to the police investigator. Should the caller share information with the call taker that would compromise identity in any way, that information is removed from the file that goes to the police investigator. Information such as "I live close enough to see what's going on" or "the suspect uses my phone to call their drug clients" is all removed by re-writing the summary of information. Through this method of screening and sanitizing the tip information, the caller can never, even accidentally, be recognized or identified by the nature of content of the tip information. The tipster remains, in terms of identity, only a number. Investigators are reminded, in each and every case, that all references to Crime Stoppers, whether it be fax or routine correspondence, be removed from the operational police file upon the arrest of the suspect or the conclusion of the case. All information is computerized, securely protected by passwords, and secured in a locked office accessible only to Crime Stoppers personnel.

Important Tips for Callers:

• DO NOT tell anyone that you have called Crime Stoppers. The only way to truly remain anonymous is if you do not tell anyone.
  
• You will be issued a confidential code number. You must keep this number a secret to ensure anonymity; the number is your only means of identification if you qualify for a cash award.
  
• Your code number should be treated like your PIN on your bank card. Keep your code number where no one else will find it.
  
• If you chose to deal directly with the police regarding the case you called Crime Stoppers about, you are no longer a part of the Crime Stoppers program and cannot be eligible for awards (because you are no longer anonymous).
