How to cancel 54d by mail
Start with your account details
Have your membership number, the home club you joined at and the name on the membership agreement to hand. The details in the letter need to match what 54d has on file.
Put the request in writing
Your Postbye letter to 54d asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – 54d”. It comes from our English template.
Mail the letter with a receipt
Take the letter to the post office and ask for certified delivery to 33146 Coral Gables. Keep the tracking number it gives you.
Hold on to the receipt
File the receipt with the letter. A 54d 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.
Where your 54d cancellation letter goes
54d can be reached by post at Ponce de Leon Boulevard 4210, Coral Gables 33146.
ZIP code 33146 places the address in Florida, in the United States.
The database also lists Buitenkant Street 54, 7925 Cape Town, South Africa for 54d. Use the first address above unless your agreement names this one.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Name, Address and E-mail.

Before you cancel 54d, check these
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
