There is a check # 9999 that cleared my account, I didn’t write a check # 9999. What is it and why?
If you set up an automatic payment with a company they may print a physical check on your behalf. Also, if you happen to overdraft an item with a business, that business may have an affiliate company charge your account a fee for the overdraft with that business. That business will typically have a written notice stating that they may charge you this fee, should you bounce a check with them.
