Introduction
The global nature of the Internet‑of‑Things (IoT) means that a single connected device may be sold in multiple regions with very different regulatory frameworks. Wireless trackers, smart sensors and embedded modules emit radio signals and connect to cellular networks, so they must satisfy safety, electromagnetic‑compatibility and network‑interoperability requirements before they can legally be sold. In this guide we summarise the major certification schemes relevant to IoT developers—FCC for the United States, CE under Europe’s Radio Equipment Directive (RED), PTCRB for the North American cellular ecosystem, and the Global Certification Forum (GCF). Understanding the purpose and scope of each scheme helps developers plan certification early and avoid costly redesigns.
FCC certification – avoiding interference and protecting consumers
The U.S. Federal Communications Commission regulates all electronic equipment that may emit radio frequency energy. The goal of FCC approval is to protect consumers and prevent radio frequency (RF) interference【555984708578607†L27-L35】. The FCC distinguishes between devices that unintentionally radiate RF energy (such as IT equipment and power adapters) and devices that intentionally transmit radio signals (such as Wi‑Fi or Bluetooth modules)【555984708578607†L45-L53】. Unintentional radiators can often be authorized via a Supplier’s Declaration of Conformity (SDoC), whereas intentional transmitters require full certification【555984708578607†L45-L53】. To obtain a Grant of Equipment Authorization for an intentional radiator, manufacturers must submit test reports from accredited laboratories along with application forms, an FCC ID label, photographs and technical documentation【555984708578607†L65-L77】. Once approved, the device can legally be marketed in the United States.
Developers should note that the FCC defines two classes of digital devices. Class A equipment is intended for commercial and industrial environments, while Class B equipment is intended for residential use and therefore must meet stricter RF emission limits【555984708578607†L31-L43】. Early pre‑compliance testing helps identify emissions issues before formal certification, saving time and expense.
CE marking and Europe’s Radio Equipment Directive
Within the European Economic Area, most electronic and radio‑enabled products require a CE mark to indicate conformity with European Union legislation. For radio equipment, the applicable law is the Radio Equipment Directive (Directive 2014/53/EU). According to a 2024 BSI briefing, the RED is an EU directive covering requirements related to the CE marking of radio equipment, including safety, electromagnetic compatibility and use of the radio spectrum【224987799204817†L5-L10】. Manufacturers must perform or commission testing and compile a technical file demonstrating compliance. Once the essential requirements are met, a manufacturer can self‑declare conformity or use a Notified Body if harmonised standards are not applied in full.
Cybersecurity is also becoming part of CE compliance. Commission Delegated Regulation (EU) 2022/30 introduces three new essential requirements for Internet‑connected radio equipment: network protection, protection of personal data, and fraud prevention【224987799204817†L19-L31】. These requirements take effect on 1 August 2025, after which CE‑marked radio equipment will need to address cybersecurity to remain compliant【224987799204817†L39-L44】. Developers of IoT devices should therefore design secure update mechanisms, data encryption and authentication from the outset.
PTCRB – meeting North American cellular network requirements
While the FCC and CE schemes verify RF emissions and safety, cellular operators in North America require an additional certification called PTCRB. The PCS Type Certification Review Board (PTCRB) was established in 1997 by select North American cellular operators【635861400895227†L141-L143】. Its purpose is to provide the framework for device certification on member networks, including the determination of test specifications and methods【635861400895227†L146-L149】. PTCRB certification is based on standards from the 3rd Generation Partnership Project (3GPP), the Open Mobile Alliance (OMA) and other standard‑development organisations【635861400895227†L164-L168】. In some cases it also accommodates requirements from the FCC, Canada’s ISED and other regulatory agencies【635861400895227†L167-L170】.
Achieving PTCRB certification ensures that a device complies with cellular network standards within PTCRB operators’ networks, and operators may block devices that are not certified【635861400895227†L176-L179】. PTCRB covers multiple device categories—including smartphones, IoT modules and connected tablets—and validates both the radio and protocol behaviour to ensure devices interoperate correctly across LTE‑M, NB‑IoT and 5G New Radio networks. For developers, PTCRB is typically required in addition to FCC approval before a cellular carrier will allow a device on its network.
GCF – global interoperability for mobile devices
To market an IoT device beyond North America, manufacturers often seek GCF certification. The Global Certification Forum (GCF) is a London‑based partnership between mobile network operators, device manufacturers and the test industry【944650013492184†L117-L121】. Founded in 1999, its members created an independent certification programme to ensure global interoperability between mobile devices and networks【944650013492184†L117-L121】. GCF certification is based on test specifications from 3GPP, 3GPP2, OMA, IMTC and the GSM Association【944650013492184†L123-L129】. Devices are evaluated by Recognised Test Organisations (RTOs) for conformance, field trials and interoperability【944650013492184†L130-L148】.
A GCF‑certified device is more likely to perform well on networks worldwide. Because certification tests replicate the “DNA” of different networks, potential issues can be resolved before product launch, enhancing the device’s commercial success【944650013492184†L139-L144】. For IoT developers planning to sell devices into multiple regions, GCF provides assurance to carriers and customers that the product will operate correctly across 4G, 5G and NB‑IoT networks.
Bringing it all together – a developer’s checklist
Consider a hypothetical asset‑tracking device with LTE‑M connectivity and GNSS positioning. To sell this tracker in the United States, you must obtain FCC certification for the intentional transmitter and ensure the device meets Class B emission limits. If you plan to sell the same device in Europe, you must meet the essential requirements of the RED and affix the CE mark, including cybersecurity provisions from 2025【224987799204817†L19-L31】. To connect to AT&T, T‑Mobile or Bell networks in North America, the device will need PTCRB certification【635861400895227†L176-L179】. For sales into Asia‑Pacific, Latin America or other regions, obtaining GCF certification can simplify operator approvals and prove global interoperability【944650013492184†L117-L121】.
Beyond these four core certifications, many IoT products also need to comply with:
- Environmental directives: The EU’s Restriction of Hazardous Substances (RoHS) directive and Waste Electrical & Electronic Equipment (WEEE) directive limit harmful substances and set end‑of‑life recycling requirements.
- Battery safety standards: Lithium batteries must pass UN 38.3 transport tests and may require UL 2054 certification for safety.
- Quality management standards: Manufacturers often maintain ISO 9001 and IATF 16949 quality systems to ensure consistent production and traceability.
By planning for these requirements early—selecting pre‑certified modules, designing for RF performance and documenting materials—developers can streamline the approval process.
Conclusion
As the IoT market matures, regulatory compliance is not a bureaucratic obstacle but a foundation for trust. The FCC protects the U.S. spectrum by limiting interference【555984708578607†L27-L35】, the CE mark signifies conformity with European safety and spectrum rules【224987799204817†L5-L10】, PTCRB ensures devices behave correctly on North American cellular networks【635861400895227†L176-L179】, and GCF certification guarantees interoperability across networks worldwide【944650013492184†L117-L121】. Understanding these programs helps developers build devices that are legal, reliable and scalable. Whether you are launching a consumer wearable or an industrial tracker, investing in certification expertise early will pay dividends when you expand into new markets.
