How to cancel Telstra by mail
Find your account details
Telstra will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.
Prepare the letter
Your Postbye letter to Telstra asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 3000 Melbourne. Keep the tracking number it gives you.
File the delivery record
Delivery confirmation is your evidence that Telstra was asked. Watch the next statement or two for any further Telstra charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Telstra cancellation letter goes
Telstra takes its post at Exhibition Street 242, 3000 Melbourne, Australia, which is where a cancellation letter belongs.
The postcode 3000 belongs to Victoria, Australia, so this is where the envelope is delivered.
Your name, address and email appear in a short block labelled Account holder, Billing address on file and Email on file, under the greeting “To Whom It May Concern,”.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
