How to cancel Blue Cross by mail
Start with your account details
Start with the member or policy number, the full name of the policyholder and the date you want the plan to end, so the request to Blue Cross names the right account the first time.
Prepare the letter
Ask Blue Cross to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Mail it with tracking
Send it certified to Toronto, Canada, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
File the receipt with the letter. A Blue Cross charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Blue Cross, check these
- Plans often end on the last day of the month. Ask which end date applies to a request sent today.
- List every dependant on the plan. Ending the policyholder's cover can end theirs too.
- Claims for care received before the end date can still be processed. Ask how to submit them after you cancel.

Cancelling a health insurance plan
Health plans end on set dates and often cover a whole household, so the request has to name the plan, every person on it and the date cover should stop, with new cover lined up first.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
