Most publishers handle General Data Protection Regulation (GDPR) and Telephone Consumer Protection Act (TCPA) compliance the same way: a policy document, a checklist, maybe a clause buried in a vendor contract. That works fine until an actual dispute shows up. For TCPA, that’s usually a lawsuit from a plaintiff’s attorney. For GDPR, it’s a request from a regulator.
Either way, you need to show exactly how a specific lead's consumer consent was captured and whether their opt-out got processed across every system. A policy document can’t answer that with the precision required. You need to establish technical specifications that explicitly tell what event actually creates a consent record, how you store it, and how a user can revoke it.
Writing a spec is an engineering task as much as a legal one. This is the part of performance marketing compliance that keeps your business safe when someone finally asks the hard question.
TCPA regulations follow the recipient, not the caller. If a phone number belongs to someone in the US, whoever dials it falls under TCPA regardless of where that business is based.
Say your affiliate company is incorporated in Brazil. If you're dialing US phone numbers, TCPA applies exactly as if you were calling from Ohio or another US city. If a separate campaign targets German traffic, GDPR applies as if you had an office, for example, in Berlin.
GDPR requirements draw the line differently: the regulation reaches any organization that offers goods or services to, or digitally monitors, people physically located in the EU.
Nationality doesn't factor into GDPR. An American tourist browsing your site from a hotel in Berlin counts, while a German citizen doing the exact same thing from a beach in Miami doesn't. What matters is where the person is physically sitting when the data gets collected, not their passport.
Same company, same registration, two completely different regulatory exposures, each triggered by where the person on the other end is.
TCPA regulations treat each call or text as a separate violation. A campaign that reached 10,000 customers without proper consent is potentially 10,000 separate violations.
Now multiply that by statutory damages – the amount the law fixes in advance for a single violation without requiring you to prove real-world harm in court – ranging from $500 to $1,500 per instance. That’s where the seven-figure exposure comes from.
The Word file called "Our Compliance Policy," which states "we always get consent before calling," won't help you. A plaintiff's attorney or the consumer (TCPA gives them the right to sue directly) can ask you to prove that this exact person gave this exact consent on the exact day.
To ensure TCPA compliance, you need technical specifications instead. Here are the two most crucial things it has to define:
Vague technical specifications produce vague enforcement. When the developer decides what counts as the trigger event and failure path, it’s undoubtedly convenient for them, but it creates a compliance hole that can cost you a lot.
When you write technical specifications, you need to define the disclosure language, timing, placement, how the user consented, and which device was used. Also, ensure that the record ties back to the specific lead.
Each of those fields needs a defined source system and a validation rule. “We have consent” isn’t defensible if you can’t precisely point to all of the details.
Technical specifications also must define retention for the consent record itself, separate from the data retention policy for the lead data it authorizes.
Once a lead is generated inside the EU, the second law comes into play. GDPR requirements demand more than TCPA does:
The numbers explain why this level of detail is worth the engineering time. Under GDPR Article 83, infringements involving the basic principles of processing, including conditions for consent, and violations of data subjects’ rights carry administrative fines of up to €20 million, or up to 4% of total worldwide annual turnover for the preceding financial year, whichever is higher.
Consent isn't static. Someone gives it, and later they can revoke it. That revocation has to propagate to every system holding that lead's data within a defined window. Under the current TCPA standard, that revocation has to be honored within 10 business days of receipt.
That said, check the current FCC rule directly before you lock a number into your spec. These numbers shift constantly, and a deadline that held yesterday might not hold today.
Your technical specifications must treat consent management as a crucial system component. It should cover three lead states:
Each state should have defined triggers for every transition, and your technical specifications must name what happens after each event.
An opt-out text should trigger a suppression flag that reaches every downstream system. It should also include advertisers you already passed that lead to. Many affiliates use third-party consent platforms to automate this process. Technical specifications must name which tool will be used as the single source of truth for consent state.
Both TCPA and GDPR regulate the whole contact. The spec has to cover every channel separately:
If you communicate with leads via email, the spec needs to cover it in detail. Pre-approved templates for warm and cold emails keep the compliance burden off the individual sender. A marketer using an approved template doesn't have to remember whether this send needs an unsubscribe link or whether this audience segment has already opted out through another channel. The spec made those decisions in advance, and the template enforces them automatically.
A regulator or attorney typically asks about how you handle the data over time. Say your consent form had one version of disclosure language 2 years ago, and you changed it a few times over the last 24 months.
If a lead contacted two years ago comes up in a dispute and you don’t keep technical specifications history, you will never know which version of the disclosure text they saw, which may cause problems.
The second piece is audit export. If a specific lead gets challenged, you need the full picture on that record. If pulling all of that takes multiple scattered systems and a hope that the timestamps line up, you need to fix it as soon as possible.
Building technical specifications before a regulator or a plaintiff's attorney asks for them costs a few days or weeks of engineering time. Building them after costs a settlement, while you're scrambling data across systems trying to reconstruct what should have been documented from day one.
If you want peace of mind when asked hard questions about a specific lead, build your technical specifications adhering to the strictest reading of the law. Technical specifications that pass TCPA and GDPR compliance automatically clear the easier ones too.
