Hotel mail order forms: how to take card details and how not to
A signed form is evidence, not permission. Learn when to use a mail order form versus a payment link, how to secure card data, and what proof helps in disputes.

Key takeaways
- A signed form is evidence of what the cardholder agreed to, not permission to charge: permission comes from your agreement with the acquiring bank.
- A payment link removes the card number from the hotel entirely, so it should be the default and the form the exception.
- The security code on the back of the card is never written down, never photographed and never stored, even for a minute.
- Every booking should keep its authorization evidence next to it, so a dispute months later is answered from one file, not from a search through a mailbox.
A mail order form is a signed instruction that lets a hotel charge a card the guest is not present with, and only your bank agreement can allow that. The safer default is a payment link, where the guest types the card on the bank's page and the hotel never sees the number. Never record the security code.
At 22:40 the reservations inbox receives a photo of a bank card, front and back, with the guest's name written on a piece of paper beside it and the words "please charge the deposit". The booking is real, the guest is waiting, and the hotel now holds something it was never designed to hold. This guide is the procedure for that moment and for everything around it: where card numbers end up in a hotel, when a hotel credit card authorization form is allowed at all, what it must contain, what to do the day a number arrives by email, who may see it, how long it stays, how it is destroyed, and what proof helps if the charge is disputed later.
Where do card numbers actually end up in a hotel?
In more places than the reservations team expects, and almost none of them were built to hold card data. The first job is to find them, because a rule you cannot enforce is not a rule.
The shared reservations inbox is the most common one. One address, several staff, automatic forwarding rules nobody remembers writing, and a synced copy on every phone that opened it. Chat apps on personal phones are worse: a guest's WhatsApp message with a card photo lands in a personal backup the hotel does not control and cannot clean up. Paper still exists too, signed forms in a drawer at the front desk, sometimes scanned later into a folder nobody remembers.
Screenshots and spreadsheets are the quiet ones: a deposits sheet with card numbers typed into a column, or a photo saved to a desktop "just for today". The OTA extranet holds virtual cards issued by an agency, which are still card data with their own rules about when they may be charged. The printer and the scanner each keep memory: a form printed and left in the tray, a scan that stays in the scanner's own storage. Even the notes field of a property management system gets used, because it accepts anything.
The practical step is a walk-through. Take one real booking from first enquiry to check-out and write down every place the number appears. That list is your starting point, not a general policy document. For how agency-issued cards differ from the guest's own card, see OTA payment terms explained: hotel collect, OTA collect and virtual cards.

What is a mail order form, and does your bank allow it?
A mail order form is the hotel's record that the cardholder authorized a charge on a card that was not present at the desk. The form does not grant permission to charge anyone: your agreement with the acquiring bank does.
Mail order, also called MOTO (mail order / telephone order), means the hotel types card details the guest gave remotely into the bank's payment screen or the hotel system's payment screen. It is a card-not-present charge: no card in hand, no chip, no PIN. When a guest later says "I did not authorize this", the money is usually recovered from the hotel first and argued about afterwards.
The bank agreement decides whether you may take mail order at all, which fields you must keep, whether the signed form must be sent to the bank, and by when. The extra confirmation step the bank runs in a browser, 3D Secure, normally does not apply to a card the hotel types in, so the protection it gives on your own website is not there. Ask your bank whether it prefers its payment link or your virtual POS for this case. Ask the question directly: is mail order allowed for us, and under which conditions.
Get the answer in writing and check it with your accountant. Nothing in this article makes a form legally valid, and bank rules differ from bank to bank and change. For the vocabulary around this, see hotel payment technology terms: virtual POS, 3D Secure, tokens and chargebacks.
Watch outA signed form is not permission
Permission comes from your acquiring bank's agreement; the form is only evidence of what the cardholder agreed to. Confirm in writing with your bank before the first mail order charge, and confirm again whenever your contract is renewed.
Which should you use: a form, a payment link or a virtual POS?
Use the payment link first, the virtual POS for your own website, and the form only where the bank agreement allows it and the guest genuinely cannot complete a link.
A payment link means the bank or payment provider hosts the page, the guest types the card, and the hotel receives a result rather than a number. A virtual POS is the checkout on the hotel's own website: same principle, the card is entered by the guest, and the bank's confirmation step can apply. Mail order means the hotel types the card. It is the fastest option on the telephone and the one that puts the number in your hands.
| Payment link | Virtual POS | Mail order form | |
|---|---|---|---|
| Who types the card | The guest | The guest | Hotel staff |
| Hotel holds full number | No | No | Yes |
| Bank's extra confirmation can apply | Yes | Yes | Usually not |
| Typical use | Deposits, prepayments | Website bookings | Phone bookings without a link |
| Main risk | Guest does not act, link expires | Guest abandons checkout | Number leaks, disputes |
The decision rule is simple. Can the guest open a link within the time you need the money? If yes, send the link. If no, ask whether mail order is allowed, and whether the amount and the guest's identity are verified well enough for the risk. If not, offer a bank transfer or payment on arrival.
Each method has trade-offs. A link needs a channel the guest reads and a guest who acts, and links expire. A form needs storage, access control, a retention period and a destruction step, which is real work every month. Whatever you choose, the number of people who can see a full card number should be as close to zero as the process allows. That target does not change with the method. For how deposits and prepayments fit into the booking, see direct booking payments: prepayment, deposits and installments.
What must a mail order form contain, field by field?
Enough to prove who authorized what, on which card, for which reservation, for how much and when, and nothing beyond that.
The cardholder section needs the full name as printed on the card, and a signature. If the person staying is not the cardholder, say so on the form and record the relationship. The card section needs the card type and the last four digits. If your bank requires the full number on the form, then the form is card data and must be stored, restricted and destroyed like card data, not filed with ordinary paperwork.
The amount and currency must be stated, and what the charge is for: a deposit, a prepayment, a full stay, or a no-show charge. The reservation reference ties it to arrival and departure dates, room type, number of nights, and the guest name if it differs from the cardholder. A plain statement of consent covers what the guest agrees to be charged, under which cancellation conditions, with a line confirming they are the cardholder. Record the date and time the authorization was given, and the channel it came through: email, telephone, or an agency.
Checklist
- Cardholder name as printed on the card
- Signature
- Card type
- Last four digits
- Amount and currency
- Purpose of the charge (deposit, prepayment, stay, no-show)
- Arrival and departure dates
- Room type and number of nights
- Guest name if different from cardholder
- Cancellation conditions accepted
- Date and time of authorization
- Channel: email, phone or agency
- Staff member who processed it
ChecklistNever on the form
- The security code from the back of the card
- A photograph of the card
- A copy of an identity document stapled to it
A labelled sample helps staff. For example, a filled form for a three-night stay with a one-night deposit, marked clearly as an illustration rather than a real booking, pinned next to the reservations desk as the model to copy.
A card number just arrived by email. What do you do that day?
Contain it, stop it spreading, move the guest to a payment link, and write down what happened. The same five steps work for a chat message, a photograph or a fax.
Do not forward the message, do not reply quoting it, and do not download the attachment to a shared drive. Every copy you make is a new place to clean up. Move the booking forward in a restricted place: the reservation record, with the number redacted, so the guest is still served and the number is not carried along.
Send the guest a payment link with one plain sentence: for your security we do not keep card details, please use this link. If the guest objects, move to the fallback options below. Record the event in a small log: date, who saw it, which mailbox or phone, what was done. One line per event is enough, and the log is what shows a pattern later.
Remove the message and any attachment from the mailbox and from the copies you control, on a schedule your adviser confirms, and do the same on the phone it reached. If the guest refuses the link, offer a bank transfer or payment on arrival rather than accepting the number. A booking lost is cheaper than a card number kept badly. Tell the guest once, calmly, that they may wish to speak to their bank. Whether to cancel the card is their decision, not the hotel's.
Key pointThe office rule
A card number is never written down, never photographed, and never stored with its security code. If it arrives anyway, it is contained the same day.
Who may see card data, how long does it stay, and how is it destroyed?
The fewest named people, the shortest period your bank, your accountant and the law allow, and a destruction step you can prove afterwards.
Name people, not roles. A list of two or three names, kept current, with access removed on the day someone leaves or changes shift pattern. Store card data apart from everything else: a locked cabinet for paper, a restricted folder for files, never the general reservations inbox or the shared drive.
There is no single retention period that fits every hotel. Your bank agreement, tax record rules and personal data rules each set something, and they differ; under the personal data law (KVKK, kişisel verilerin korunması kanunu) retention must also be justified and limited. Ask your accountant and your adviser, write the answer down, and follow it. Destroy on a schedule: cross-cut shredding for paper, secure deletion for files, and a one-line destruction log with date, what was destroyed and who did it.
The security code is never stored at all, even briefly. The card schemes' security rules and your bank's agreement treat keeping it after authorization as a serious failure. Test once a year: pick one booking and try to find every copy of its card number. What you cannot find is either destroyed or invisible, and you need to know which.
Checklist
- Named access list exists and is current
- Access removed on the day of departure
- Card data stored separately from ordinary files
- Retention period written down and approved by accountant and adviser
- Destruction schedule set
- Destruction log kept
- Security code never stored
- Annual search test completed
What proof helps if the charge is disputed later?
The evidence that helps is a chain showing the cardholder authorized this amount for this stay, and that the stay actually happened.
Keep the authorization evidence with the reservation, not in a separate folder: the signed form or the payment link result, and the correspondence where the guest asked for the charge. Show the stay: registration details, the check-in record, the guest bill with the guest's signature, and the departure record.
A payment link result carries the bank's own confirmation, which is stronger than a form the hotel filled in and the guest signed. A form alone is weak if the guest says they never authorized it and never stayed. The stay record is what closes that gap.
The list of accepted evidence and the deadlines for answering are set by the card schemes and your bank, and they change. Ask for the current list before you need it. File everything so it can be retrieved by reservation number, not by date. A dispute answered in a day looks very different from one answered in a week. For the full procedure, see card chargebacks at hotels: answering a dispute with the right evidence.
What to do next
Write the one-page rule for the reservations office today: the payment link is the default; a card number that arrives by email is contained the same day; the form is used only where the bank agreement allows it, and is stored and destroyed on a written schedule; every booking keeps its authorization evidence beside it. Then send your bank one written question, whether mail order is allowed for your hotel and on which conditions, because that answer decides which of these procedures you are actually allowed to run.
Frequently asked questions
Is a mail order form legally valid in Türkiye?
The form is evidence, not a legal instrument that creates a right to charge. Whether a charge is valid depends on your agreement with the acquiring bank and on the general rules that apply to the transaction. Ask your bank in writing and take advice from your accountant or legal adviser on your own case; do not treat a hotel credit card authorization form template found online as approval.
Can a guest send their card details by WhatsApp?
They can, and some will, but the hotel should not invite it and should not keep it. The message lands on a personal phone with a personal backup, outside any access control the hotel has. Reply with a payment link and one sentence explaining why.
What is the difference between a mail order form and a payment link?
Who types the card. With a form, the hotel types the number and therefore holds it; with a link, the guest types it on the bank's page and the hotel receives only a result. The link also lets the bank's extra confirmation step apply, which a typed card usually does not.
How long should we keep signed mail order forms?
There is no single number that fits every hotel, because your bank agreement, tax record rules and personal data rules each set something and they differ. Decide with your accountant and your adviser, write the period down, and destroy on schedule with a log. Keeping forms forever is a decision too, and a costly one.
The guest cannot use a payment link. What else can we offer?
A bank transfer to the hotel's account, payment on arrival, or a virtual card issued by the travel agency that made the booking. All three keep the card number out of the hotel's mailbox. If none is possible and the bank allows mail order, use the form, store it as card data and destroy it on schedule.
