What is a FCC ID?
An FCC ID validator checks whether a given FCC equipment authorisation ID follows the structural format defined by the US Federal Communications Commission. The FCC ID is the unique identifier assigned to wireless devices, smartphones, routers, Bluetooth headphones, remote controls, smart home devices, that have been tested and authorised for use in the United States.
Every device that intentionally transmits or receives radio frequency signals must obtain FCC equipment authorisation before being marketed in the US. The FCC ID appears on the device label and in device settings, allowing regulators, consumers, and compliance engineers to identify the device and look it up in the FCC's public database.
The FCC ID has a two-part structure: a grantee code of 3–5 characters identifying the manufacturer (assigned by the FCC), followed by a product code of 1–14 characters identifying the specific device model (assigned by the manufacturer). The characters I, O, and Q are excluded from grantee codes to prevent visual confusion with digits. This validator checks that structure: correct grantee code length, no forbidden characters, and a present product code.
This is a format check only. A structurally valid FCC ID is not automatically a confirmation that the device is listed in the FCC Equipment Authorisation database, that requires a query to the FCC's public search system. Use this validator to confirm format correctness before making an API call, or to catch obvious transcription errors in device labels.
Why Use an FCC ID Validator?
Compliance and procurement workflows often involve verifying that a batch of devices carries valid FCC authorisation. An FCC ID with a forbidden character or an invalid grantee code length is immediately suspicious, it may indicate a counterfeit device, a transcription error, or a label applied to the wrong product. Catching this at the format-check stage is faster than querying the FCC database for every ID.
For developers building device inventory or compliance systems, the validator provides a quick client-side check before submitting to backend lookup services.
Who Should Use This Validator?
Compliance engineers at companies importing or distributing wireless devices in the US need to confirm that every device in their inventory has a valid FCC ID before sale. A format check is the first step in that process.
Procurement teams purchasing bulk electronics need to verify that quoted devices have real FCC authorisation. An invalid FCC ID format on a product sheet is a red flag for counterfeit or grey-market goods.
Developers building device registration or asset management platforms can use the format validator as a client-side input check before querying the FCC API.
Consumers who want to verify that a second-hand device they purchased carries genuine FCC authorisation can check the format here and then look up the full ID in the FCC database.
What Insights Does the FCC ID Validator Give You?
A valid result shows you the grantee code and product code separated, confirming the structure was parsed correctly. The grantee code identifies the manufacturer, you can look it up in the FCC's grantee database to confirm which company it belongs to.
An invalid result tells you exactly what is wrong: the grantee code is too short, a forbidden character was found, or the product code is missing. This points directly to the source of the problem, whether it is a data entry error, a label issue, or a potentially non-authentic device.
How to use this FCC ID calculator
- Find the FCC ID on your device, look in Settings > About, or on the back or bottom label.
- Enter or paste it into the FCC ID field. You can include or omit the hyphen separator.
- The result shows immediately: Valid with the parsed grantee and product codes, or Invalid with the specific format issue.
- If valid, use the grantee code to look up the manufacturer in the FCC's public grantee database.
- For a full device record, search the complete FCC ID in the FCC Equipment Authorisation database.

Formula & Methodology
The validator applies the following rules to the FCC ID (after stripping hyphens and spaces): 1. Length: Total length must be between 4 and 19 characters. 2. Grantee code: First 3–5 characters must be alphanumeric. Characters I, O, and Q are not permitted. The validator tries 5-character, then 4-character, then 3-character grantee codes and takes the longest valid match. 3. Product code: The remaining characters after the grantee code must be at least 1 character, containing only letters (A–Z) and digits (0–9). Valid examples: -PY317334A, grantee PY3, product 17334A -BCGA2HBCGA, grantee BCG, product A2HBCGA Invalid examples: -IO3PROD1, grantee code contains O (forbidden) -AB, too short, no product code -1234567890123456789, exceeds maximum length
