The addresses we hold
The address a cancellation letter to Exelon needs, and every other address we hold, starting in Warrenville: copy the lines exactly and the envelope sorts itself.
Where the letter goesMailing address

How to address the envelope
Use the address letter for letter
The front of the envelope carries 4300 Winfield Road, Warrenville, IL 60555 and nothing else in the address block. Check the 60555 digit by digit before it goes in the post.
Add your return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Buy the certified service
At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.
Keep the records
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The cancellation letter
A plain, dated letter to Exelon asking for the cancellation, the end of every charge and written confirmation. Have the name and email on the account and, if you have one, an account or customer number to hand; our letter template fills the same shape in on screen.
