How to cancel ComEd by mail
Get your account details together
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to ComEd is only as good as the details it quotes.
Set out the request
Ask ComEd 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: Subscription termination – ComEd”.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 60680-5398 Chicago. Keep the tracking number it gives you.
Save the tracking record
The receipt dates your request. Look at your next statement for any ComEd charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your ComEd cancellation letter goes

With ZIP 60680-5398, the address sits in Illinois and the letter never leaves the United States postal system.

Before you cancel ComEd, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
