Also called: Call center authorization, Manual authorization
What voice authorization is
Voice authorization is a manual way to request approval for a card transaction by phone. You use it when your payment device cannot connect for electronic authorization or when a transaction response directs you to call. The person or automated system you reach checks the request and, if approved, gives you an authorization code.
That code is approval to proceed with the transaction, not proof that the sale has been captured or settled. You still need to follow your processor’s instructions to submit the approved transaction for settlement. If you take the payment details but never enter the code and complete that step, the sale might not be paid.
A phone approval is only one step: record the code, then complete the transaction for settlement.
How it works
Have your merchant ID and the customer’s payment details ready before calling. The authorization process differs by payment setup, so use the phone number and prompts provided for your account. If the request is approved, record the authorization code and enter it with the transaction when you complete the sale.
A phone authorization is also used for some additional verification, including an address verification service (AVS) check. A match result is not the same as approval of a sale. Keep the authorization code and transaction details with your business records so you can reconcile the transaction against your sales and settlement reports.
What it means for your costs
Voice authorization does not have one standard fee across providers. A published American Express guide lists a 0.65% voice-authorization fee, while another published fee guide reports charges starting around $0.50 per authorization. Those figures are undated examples, not a confirmed current rate or a universal price. The fee for your account depends on its pricing terms.
On your statement, look for descriptions such as “voice auth” or “manual auth.” Compare the count of those charges with your records of phone-authorized transactions. If a fee appears repeatedly, confirm that each charge matches a real call. A working terminal and connection reduce the need to use this manual fallback, but they do not change fees already set out in your pricing.
What to watch
A voice approval does not remove the need to complete the transaction correctly, keep the approval code, or follow your normal procedures for verifying the sale. During an outage, write down each approved amount and code, then enter the transactions as soon as your payment system is available. That gives you a record to compare with your batch and funding totals.
What you can actually change
- Keep the details ready. Store your merchant ID and the correct authorization phone instructions where staff can find them. Record the approval code and amount for every call.
- Complete approved sales. Enter the authorization code using your processor’s capture or settlement process. Reconcile the sale against your batch and funding records.
- Audit the fee lines. Search your statement for “voice auth” and “manual auth.” Compare each charge with your call log and your account’s listed fee.
Frequently asked questions
Does voice authorization guarantee that I will receive payment?
No. It provides an approval code for the card transaction. You still need to complete the required capture or submission step and reconcile the sale against your settlement records.
When should I use voice authorization?
Use it when your payment device is unavailable or when the transaction response instructs you to call for approval or additional verification. Follow the process and phone instructions for your payment setup.
How much does voice authorization cost?
There is no single standard fee. Published examples include a 0.65% fee and a charge starting around $0.50 per authorization, but those figures are undated and are not a current price guarantee. Look for “voice auth” or “manual auth” on your statement.
