PCI DSS Call Recording
Most merchants will need to record phone calls between staff and customers for one reason or another. In fact, in many industries involving cardholder data, it’s necessary to record calls to be PCI DSS compliant.

PCI DSS Call Recording Requirements
Often, organisations will also use these calls for additional reasons, such as staff training and monitoring or customer service and complaints reviews.
However, when taking card payments from a customer over the phone, there are several challenges the company must consider in handling the data appropriately whilst recording the call.

PCI DSS call recording in brief
- Call recordings can capture vulnerable cardholder information, including PAN and CV2 numbers.
- Retaining that information in audio would put a company in breach of PCI DSS regulations.
- Merchants taking phone orders need to handle and dispose of cardholder data appropriately to remain PCI DSS compliant.

What are the PCI DSS call recording requirements?
For merchants that take product or service orders over the phone, it’s important to comply with PCI DSS call recording requirements.
When a customer reads out their card details to your customer service agent, vulnerable cardholder information including the PAN and CV2 numbers would be captured in the audio. Retaining this information through call recording would lead to your company being in breach of PCI DSS regulations, so it’s important to dispose of this information appropriately to remain compliant.
What are the best methods when call recording for PCI DSS compliance?
If your business needs to employ call recording whilst remaining PCI DSS compliant, there are a few methods you could use.
| Method | How it handles card data | Trade-off stated in the article |
|---|---|---|
| Tagging and masking | Record calls as usual, then tag payment calls and mask the card information afterward. | White noise can work, but the technique is time-consuming and needs care. |
| Pause and resume | Pause the recording while the customer gives card details, then continue after payment. | Manual use still leaves risk from human error or negligence. |
| De-scoping | Customers key card numbers directly through the telephone keypad so agents do not hear the data. | The keypad tone is often already masked, keeping data unidentifiable. |
| Avoid recording calls | Do not record calls, especially where a clean room environment prevents agents obtaining card details. | This removes review value for training and complaints, and may not fit regulated call recording. |

Call recording methods compared
- Tagging and masking conceals card information after payment, often by overlaying white noise.
- Pause and resume avoids capturing cardholder data in the recording, but manual handling can still fail.
- De-scoping lets customers key card numbers directly so agents do not hear or access the cardholder data.
- Avoiding recordings can help in clean room environments, but only where recording is not a regulatory requirement.

Tagging and masking
This method is fairly straightforward. Your customer service team will need to record all calls as usual, including when taking customer payments. However, immediately after taking payment on a call, you will need to ‘tag’ the call as such, so that you can go back into the recording afterward and conceal, or ‘mask’ the card information.
One of the most effective ways to mask the cardholder data over the phone is to overlay the audio with white noise so the information cannot be heard. Although proven to work, this is a somewhat time-consuming technique that would need to be done with care, as any human error or negligence could still leave you vulnerable to a breach.
Pause and resume
By using the ‘pause and resume’ approach, your team can record the call without capturing any cardholder data in the audio whatsoever. When taking the call, the agent will pause the call whilst the customer gives their card details. Once the payment has gone through, the recording can continue.
As a manual process, it’s still worth considering that the risk of a breach is still present through either human error or negligence. However, it is possible to automate this process, using compliance automation to reduce this risk. Additionally, with the audio missing, it would be hard to pinpoint what happened if something did go wrong.
De-scoping your call center and call recordings
De-scoping may be one of the most effective ways of disguising card data whilst still recording the call. This involves customers keying their card numbers directly using their telephone keypad, instead of reading them out. The sound of the keypad tone is often already masked, meaning that the agent will not hear or have direct access to their cardholder data information, rendering them completely unidentifiable.
Avoid recording calls
If your business is able, the easiest option is to not record calls at all. This is particularly effective if your customer service team operates in a ‘clean room’ environment – this means somewhere where there’s no possible way for the agents to obtain the cardholder information themselves.
Although this method will help you avoid a breach, the downside is that you wouldn’t have the advantage of being able to review staff training and the complaints service. ‘Clean room’ environments are also less common with the advent of home working. Additionally, this option is only available if you’re in an industry where call recording isn’t a regulatory requirement.

Hicomply's take
Hicomply recommends treating call recording as a scoping decision first and a technology decision second: reduce where cardholder data can appear, then collect evidence that the chosen process is followed every time. Teams that keep PCI DSS policies, call-handling procedures, and review evidence in one compliance resource set are better placed to stay audit-ready without relying on spreadsheets.
