*Account checks say whether an account exists. They never say whose it is.*


The Netflix check indicates whether a Netflix account is associated with a phone number. It runs in real time and in bulk jobs, for numbers from any country, and answers `registered: true`, `false` or `null` (unknown) with the time of the check. It never returns profiles, viewing history or plan details.

## What does the Netflix check tell you?

It tells you whether a phone number is linked to a Netflix account. Netflix accounts are paid subscriptions held by one member and shared within a household. A phone number can be added for sign-in and account recovery, but most accounts are created with an e-mail address.

- `registered: true`: a Netflix account is associated with the number.
- `registered: false`: a conclusive "no". Common, because many accounts have no phone number and many people use someone else's account.
- `registered: null`: no conclusive answer. Not charged.

Netflix reported more than 300 million paid memberships in its fourth-quarter 2024 shareholder letter (January 2025). Accounts are spread across most countries, but one account usually covers a whole household. So `true` says something about the account holder's number, not about each person who watches.

## Who uses it, and why?

A paid subscription is harder to fake than a free sign-up, so a number linked to one is a useful signal that the number is established and in everyday use.

- **Trial and promotion abuse.** Subscription businesses see repeated free-trial sign-ups from freshly obtained numbers. A number with no history on large consumer services can be routed to extra verification, and one with history can pass straight through. See [OTP and sign-up fraud](/use-cases/otp-and-signup-fraud).
- **Account security.** When a recovery number changes, history on other paid services is one mild reassurance.

Netflix tightened account-sharing rules in 2023, which pushed more people to hold their own accounts. That trend may make the signal slightly more useful over time, but it is not a reason to rely on it alone.

## What do you get back?

Each number gets one result under `checks["netflix.registered"]`, with no extra attributes.

| Field | Type | Meaning |
|---|---|---|
| `registered` | boolean or null | `true` account associated, `false` none, `null` unknown |
| `status` | enum | `completed`, `pending`, `unknown`, `unsupported_country` or `failed` |
| `confidence` / `confidence_score` | enum / 0–1 | How sure the answer is |
| `checked_at` | timestamp | When the answer was obtained |
| `cached` / `billed` | boolean | Served from cache; charged or not |
| `reason` | string or null | Why an answer is not conclusive |

## How is it billed?

You pay per number checked, only for conclusive answers. You're not charged for inconclusive results (unknown, unsupported country, timeout, invalid, duplicate). Real-time and bulk checks are priced separately. See [pricing](/pricing). Cache hits are free, and `max_age: 0` forces a fresh, billed check.

## What are the limits?

- Real time (`POST /v1/lookup`, up to 100 identifiers) and bulk jobs (`POST /v1/jobs`, up to 50,000 per job), for numbers from every country.
- Up to 20 checks per request. Numbers × checks is capped at 2,000 per lookup and 100,000 per job.
- Requests that look like sequential number ranges or generated e-mail lists are rejected.
- A daily cap per account applies (`GET /v1/limits`).

## How do I use it responsibly?

Use the answer to protect sign-ups and offers, only for numbers you have a lawful basis to process. Don't use it to infer how people spend their money or to decide on eligibility for anything. The [acceptable use policy](/legal/acceptable-use) forbids profiling and unsolicited messaging. People can object at [/opt-out](/opt-out).

## Example request

With a test key, `+447700900001` answers "registered". See [test mode](/docs/test-mode).

## Frequently asked questions

### Does the check say who in a household uses Netflix?

No. A Netflix account is shared by a household, and the check only indicates whether an account is associated with the number. It returns no names, profiles, viewing history or plan details.

### Why is this useful outside the streaming business?

A paid subscription account linked to a number suggests a long-used, everyday number. Subscription and promotion businesses use it as one signal against sign-ups from throwaway numbers.

### Can I check an e-mail address instead?

Yes. The netflix.email service answers the same question for an e-mail address, in real time.

### Is a number without a Netflix account suspicious?

No. Most accounts are created with an e-mail address, and many households share one account. On its own, false says very little.

### Which countries are covered?

Numbers from any country can be checked. Netflix is available in most countries, though not all.
