How to search the FDA 510(k) database and read a record
A field-by-field guide to FDA's 510(k) Premarket Notification database, the De Novo and PMA databases next to it, and the openFDA API.
Updated · Sources: FDA and openFDA, linked below
FDA's 510(k) database is at accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm. If you have a number such as K250507, type it in the 510(k) Number box and search. If you don't, search by Applicant Name or Device Name, then use the three-letter Product Code to find every device of the same type.
For PPG, pulse oximeter and wearable devices you can also filter our FDA database of 459 records by company, product code, year and Rx/OTC, and share the filtered link.
Which database to search
| Database | Numbers | Use it for |
|---|---|---|
| 510(k) Premarket Notification | K + six digits | Cleared devices: most Class II and some Class I and III |
| De Novo | DEN + six digits | New device types granted without a predicate |
| Premarket Approval (PMA) | P + six digits | Approved Class III devices |
If you are not sure which pathway applies, read FDA cleared vs approved first. FDA also offers downloadable 510(k) files for bulk work.
The search fields
The form fields, in the order FDA shows them:
| Field | What to enter | Tip |
|---|---|---|
| 510(k) Number | The full number, for example K250507 | Fastest route. It opens the record directly. |
| Type | Traditional, Special or Abbreviated | Special 510(k)s are usually changes to the company's own device. |
| Product Code | Three letters, for example DQA or QDB | The best way to list every device of one type. |
| Applicant Name | Part of the company's legal name | Search a short distinctive word. Suffixes and typos vary. |
| Device Name | Part of the name on the submission | This is the submitted name, which can differ from the retail name. |
| Panel | The review panel, for example Cardiovascular | Useful with a date range to scan a specialty. |
| Decision | For example SUBST EQUIV (SESE) | Leave blank to see every decision. |
| Decision Date | A from and to date | Combine with a product code to see what is new. |
| Third Party Reviewed, Clinical Trials, Predetermined Change Control Plan Authorized | Check boxes | Narrow a result list once it is already small. |
| Sort by | Decision date, device name, applicant or 510(k) number | Decision date (descending) puts the newest first. |
Applicant names are the legal entity on the submission, written the way the company filed them. FDA's records, for example, list the same pulse oximeter maker as both "Beijing Choice Electronic Technology" and "Beijing Choice Electronic Technololgy". A search for "Beijing Choice" finds both.
Reading a 510(k) record
Opening a number shows one record page. Here is what each line means, using K250507, Apple, Inc.'s Hypertension Notification Feature (HTNF), as the example.
| Field on FDA's page | Meaning | K250507 |
|---|---|---|
| Device Classification Name | FDA's name for the device type behind the product code | Hypertension Machine Learning-Based Notification Software |
| 510(k) Number | The submission number | K250507 |
| Device Name | The name on the submission | Hypertension Notification Feature (HTNF) |
| Applicant | The company that submitted it, with its address | Apple, Inc. |
| Regulation Number | The 21 CFR section that classifies this device type | 870.2380 |
| Classification Product Code | Three-letter code for the device type | SFR |
| Date Received / Decision Date | When FDA received the submission and when it decided | Feb 21, 2025 / Sep 11, 2025 |
| Decision | The outcome, with its code | Substantially Equivalent (SESE) |
| Summary / Statement | Link to the 510(k) summary PDF, or a 510(k) statement | Summary PDF |
| Type | Traditional, Special or Abbreviated | Traditional |
| Reviewed by Third Party | Whether an FDA-recognized third party did the review | Shown on FDA's page |
| Predetermined Change Control Plan Authorized | Whether FDA authorized a plan for specified future changes | Shown on FDA's page |
The record page does not list the predicate or the full indications for use. Those are in the summary PDF: the indications usually appear on an "Indications for Use" page, and the summary names the predicate device and compares it with the new one. A 510(k) statement replaces the summary with a certification, under 21 CFR 807.93, that the submitter will provide the information within 30 days of a written request.
Search by product code
The product code is the most reliable way to find comparable devices, because it reflects how FDA classified the device instead of what the company calls it. Codes that matter for PPG and wearables:
| Code | FDA name | Records in our database |
|---|---|---|
| DQA | Oximeter | 151 |
| QDB | Photoplethysmograph Analysis Software For Over-The-Counter Use | 5 |
| QDA | Electrocardiograph Software For Over-The-Counter Use | 9 |
| SFR | Hypertension Machine Learning-Based Notification Software | 1 |
| QZW | Over-The-Counter Device To Assess Risk Of Sleep Apnea | 3 |
The full list of codes we cover, with FDA's definitions, is on the FDA database page.
Search with the openFDA API
For repeatable lookups, the openFDA device 510(k) endpoint returns JSON with fields such as k_number, applicant, device_name, product_code, date_received, decision_date and decision_code. A single record:
https://api.fda.gov/device/510k.json?search=k_number:K250507Every record under one product code, newest first:
https://api.fda.gov/device/510k.json?search=product_code:QDB&sort=decision_date:desc&limit=100The endpoint also carries De Novo (DEN) numbers. It does not include predicates, indications or Rx/OTC status, which come only from the PDFs. openFDA updates roughly weekly and lags FDA's website, so a brand-new decision may show on accessdata.fda.gov before it reaches the API.
Common mistakes
- Searching by brand. The applicant is a legal entity, and one brand can file under more than one name.
- Treating one clearance as covering every feature. Each software feature on a watch can have its own number.
- Looking for a De Novo in 510(k) results. Use the De Novo database or search the DEN number.
- Reading "cleared" as "approved". They are different FDA decisions; see cleared vs approved.
- Assuming no record means a device is sold illegally. Many devices are exempt from 510(k).
A filtered view for PPG and wearable devices
Our FDA database pulls the PPG, pulse oximetry, wearable ECG, blood pressure, sleep and monitoring records into one table, with filters FDA's form doesn't have: claim, sensor type and Rx/OTC. Some starting points:
- Pulse oximeters and SpO2 devices
- Wrist PPG devices and features
- De Novo grants
- Records with OTC use stated in FDA documents
- Photoplethysmograph analysis software (QDB)
Every row links to its FDA record. Indications, predicates and Rx/OTC there are parsed from FDA PDFs and labelled that way, so check the PDF before you quote them.
Questions
- What is the FDA 510(k) database?
- It is FDA's public, searchable list of premarket notification (510(k)) decisions, hosted on accessdata.fda.gov. Each entry shows the 510(k) number, applicant, device name, product code, regulation, dates and decision, with a link to the summary or statement when FDA has posted one.
- How do I look up a 510(k) number?
- Type the full number, a K followed by six digits, into the 510(k) Number box on FDA's search page and press Search. The record page opens directly. Numbers that start with DEN are De Novo requests and live in FDA's separate De Novo database.
- Why can't I find a device in the 510(k) database?
- Common reasons: the device is exempt from 510(k); it was authorized through De Novo or PMA, which have their own databases; it is filed under the applicant's legal name rather than the brand; or the decision is newer than the data you are searching. Tools built on openFDA lag FDA's website by days to weeks.
- What does SESE mean on a 510(k) record?
- SESE is FDA's decision code for "substantially equivalent". The search form lists other decision codes too, such as SESU (substantially equivalent with limitations) and SESK (substantially equivalent, kit).
- What is the difference between a 510(k) summary and a 510(k) statement?
- A summary is a public document describing the device, its predicate and the testing behind the submission. A statement is a certification under 21 CFR 807.93 that the submitter will provide the submission's safety and effectiveness information within 30 days of a written request.
- Is there an API for the 510(k) database?
- Yes. openFDA's device 510(k) endpoint (api.fda.gov/device/510k.json) returns the same core fields as JSON and also carries De Novo numbers. Our database uses it; its data currently runs through Oct 26, 2026.
