PCI Compliance Levels: A Guide to Requirements and Best Practices

PCI compliance levels are a crucial aspect of ensuring the security of credit card transactions. There are four main levels of compliance, each with its own set of requirements.

Level 1 merchants are required to undergo annual on-site assessments, which can be a costly and time-consuming process. This is because they process over 6 million transactions annually.

Level 2 merchants, on the other hand, are required to submit quarterly network security scans, which can help identify vulnerabilities before they become major issues.

To determine your PCI compliance level, check your card transaction volume for the most recent 52-week period. This will give you a clear idea of your business's payment activity.

Communicate with your acquiring bank or customers to understand their PCI requirements for your business. Each card payment brand has its own standard criteria, but they're generally similar.

Calculating your annual transaction volume accurately is crucial for choosing the correct compliance level. Start by looking at your records for credit and debit card transactions from the previous year.

A PCI SAQ, or Self-Assessment Questionnaire, is a merchant's statement of PCI compliance, validating that the merchant is taking the necessary measures to secure cardholder data.

There are different types of SAQ, and the type you need to submit depends on your level and how you process payment card data. You can outsource your card data processing to third parties, in which case you'll need to submit an SAQ A.

SAQ A is for organizations that completely outsource their card data processing to third parties, including eCommerce transactions and mail/phone order merchants.

For eCommerce merchants that only outsource their payment processing, you'll need to submit an SAQ A-EP. This type of SAQ is specifically for eCommerce merchants.

If you're an eCommerce business that doesn't obtain cardholder data but controls the way it's forwarded to third-party payment processors, you'll need to submit an SAQ B.

Here are the different types of SAQ:

Each type of SAQ has its own specific requirements and guidelines, so it's essential to choose the right one for your business.

To determine your PCI compliance level, you need to check your card transaction volume for the most recent 52-week period. This will give you a clear picture of your business's transaction activity.

You can get this information from your acquiring bank or customers, who may have specific requirements for your business. Card payment brands also have their own standard criteria for compliance levels.

It's essential to calculate your annual transaction volume accurately, breaking down the volume by type, especially if you handle both e-commerce and in-person payments. This will help you choose the correct compliance level.

Partnering with PCI-compliant vendors can make achieving compliance much easier, as they already have security measures in place. By working with them, you can leverage their compliance measures while maintaining your own standards.

If you have trouble accessing your transaction volume information or want confirmation on your compliance level, you can contact the card payment brand(s) you accept, your acquiring bank, customers, or whichever organization is requesting PCI DSS compliance from your business.
