Things to Know
If you accidentally provide the wrong inmate ID number and another inmate happens to have the ID you used, that inmate will get the package. MyCarePack.com will not refund the money. Be sure of the ID number before completing an order. (If you are unsure and the site does not provide it, ask the inmate what it is when he calls or writes).
You are allowed to send one package per week to each inmate.
If an inmate is prohibited from having certain items, MyCarePack.com will refund the amount of that item back to your card. This refund typically appears five to seven business days later.
If an item is not available the company tries to match it with a similar item. If one cannot be found your card is refunded the amount of that item. You are not given the choice between a substitute item or a refund for the item.
Prepaid debit cards might be rejected because an address has to match up before the order can go through. Many pre-paid cards do not require an address on file, therefore MyCarePack.com’s anti-fraud steps might reject the card due to invalid address.
Do not use spaces or dashes when entering your credit/debit card number.
Each facility details spending and account limits. The button is in lower left area of the page after you select the facility and press “Enter”. If you don’t comply with the stated limits your order will be rejected.
You will notice a $1.00 pending charge on your statement. This charge is used to verify the pre-authorizing of the card and will not actually be withdrawn from the account. It will be released back to the account a few days after it happens.
Inmates typically receive their care packages two to seven days after they are purchased.
