The addresses we hold
One place for Sonic Boom Net's mailing addresses: the Headingley delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.
Where the letter goesMailing address
Sonic Boom NetInglenook Road 260R4H 1C8 HeadingleyCanadaThe Canada address on file for Sonic Boom Net. Postal code R4H 1C8.
How to address the envelope
Use the address letter for letter
The envelope reads Inglenook Road 260, R4H 1C8 Headingley, Canada. Match the spacing and the box or street line exactly as printed.
Put your own address on it
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Ask for certified mail
Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Headingley is traceable from the article number until it is signed for.
File the receipt with your copy
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.
