Note: Cancellations are not necessary if you are replacing an existing certificate. The replacing will automatically cancel the existing certificate.

Step 1 -- File number, service center number and the serial number of the certificate you wish to cancel. The file number is a 4-digit number that is preceded by either BP or an S, such as BP1234 or S0123.
Step 2 -- Fill in the correct alarm company information as well as the protected property information in the boxes. If the address is incorrect for either the alarm company or the protected property, the cancellation will be rejected and sent back.
Step 3 -- Sign and date the cancellation request. Requests without signatures will be rejected and sent back.
Step 4 -- Select the appropriate reason for canceling the certificate. For example, service discontinued or subscriber moved.
Step 5 -- Make a copy of the cancellation request for your records. Note: If you are still using the 2-page carbonless forms, please mail only the top copy to UL. The second page is for your records.
Step 6 -- Mail the request to UL at address listed below:

Underwriters Laboratories Inc.
333 Pfingsten Road
Department 3017M
Northbrook, IL 60062

Upon cancellation, a confirmation letter from UL will be mailed to both the alarm company and the protected property.
