How to cancel NCSA by mail
Gather your account details
NCSA will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
The letter asks NCSA to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – NCSA”. Postbye fills it in from our English template.
Post the letter
Send it certified to Chicago, United States, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date NCSA was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your NCSA cancellation letter goes
NCSA can be reached by post at 1333 Floor 4 N Kingsbury St, Chicago, IL 60642.

Before you cancel NCSA, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
