How to cancel IQScore by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at IQScore is the easiest one to set aside.
Write the cancellation request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – IQScore”: close the IQScore account, stop every charge and reply in writing.
Post it with proof of delivery
Use certified mail for the 19806 Wilmington address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
The receipt dates your request. Look at your next statement for any IQScore charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your IQScore cancellation letter goes
IQScore lists 1207 Delaware Ave #4549, Wilmington, DE 19806 as its mailing address.
ZIP code 19806 is in Delaware, so the letter stays inside the United States postal system.
Your name, address and email appear in a short block labelled Name, Address and E-mail, under the greeting “To Whom It May Concern,”.

Before you cancel IQScore, 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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
