This is likely what they meant by snail mail, this is the welcome letter I received today from Carolina Co-op.
Welcome! You are just a few steps away from obtaining account membership with Carolina Cooperative Federal Credit Union. You will be receiving a packet in the mail that contains important documents that will need to be reviewed, completed, and returned. Instructions are included to help guide you through the paperwork. Your initial account opening is unavailable electronically, so please watch your USPS mail delivery for your packet.
If you are applying for a loan, it takes an average of 5 business days once your savings account is open with its deposit. With Carolina Cooperative FCU, you must have at least a savings account to be able to apply for any of our loan products. A copy of your valid driver’s license(required for auto loan applicants) or valid state issued ID is required for your account opening and must have the correct address where you currently live, or we must have address verification. Our lending options do not stop at auto loans. We also offer personal loans, Visa credit cards with exceptional rates, secured loans, and recreational vehicle loans!
If you are looking to refinance your current auto loan or are at your end of lease buy out time period, please note that we are only able to refinance auto loans for those who reside in North Carolina or its connecting states, and private vehicle sales are only obtainable within the state of North Carolina.
Once you have completed the documents in your account opening packet, if you wish to expedite the process, you may do so at your expense with the express courier of your choice.
